Everything You Ever Wanted To Know About Wheel Spacers

Why Use Wheel Spacers?

-Appearance. You want to push the wheels out for a better stance and more aggressive look. This is totally subjective to your personal tastes. And we can’t tell you what to like…

-Clearance. Many wheels are not compatible with big brake kits. The spoke of the wheel will scrape the new brake caliper and you need a wheel spacer to push the wheel spoke away from the caliper.

-Correction. You may have bought a set of wheels that don’t have the correct offset for your car. The offset may be too high, resulting in the wheels sitting too far inward. This is both ugly and incorrect as the tire can now rub on the inside wheel well, or on suspension components, etc. A wheel spacer will push the wheel out and ‘correct’ the offset.

-Handling. By spacing the wheels further apart, you can make the car more stable and corner better. You can gain a similar effect as adding a wider wheel without the added weight and expense.

Driving dynamics and sporting performance are substantially enhanced. Luxury and presence are further refined.

All-new V8 engine
Improved performance
Refinement of the outstanding chassis and suspension
Refinement in design
New equipment and features
Woodcliff Lake , NJ – January 27, 2005… The most successful 7 Series in the history of BMW will set a new standard in the luxury performance class once again as it enters the 2006 model year. A significant improvement in performance along with enhancements to the chassis and suspension reaffirm the BMW 7 Series as the driver’s car in the segment. Refinement in design, in turn, expresses the car’s enhanced driving dynamics and sportiness at very first glance while retaining the unmistakable presence that gives the BMW 7 Series its elegant and charismatic character.

BMW 750i and 750Li: Powered by an all-new VALVETRONIC V8.

The 2006 750i and 750Li will feature a new 4.8 liter VALVETRONIC V8 engine capable of 360 horsepower (SAE net) and 360 lb-ft of torque. The new models are even more responsive than their predecessors, with a 0–60 mph time of just 5.8 seconds.

BMW 760i and 760Li: Twelve-cylinder engine with a unique combination of direct fuel injection and VALVETRONIC.

Launched in 2003, the BMW 760i/Li V12 remains unchanged, with engine output of 438 horsepower (SAE net) and maximum torque of 444 lb-ft. With its combination of four-valve technology, VALVETRONIC, double-VANOS and direct fuel injection, the BMW 760i/Li remains unique in the marketplace. VALVETRONIC ensures the engine’s very high level of fuel economy under partial load. Direct fuel injection, in turn, serves to increase both torque and output.

New engines reflect BMW’s ongoing commitment to the ultimate driving experience: More power, greater efficiency, lower emissions.

Together with its ongoing model initiative, BMW’s recent engine initiative ensures that BMW will continue to deliver the ultimate driving machine.

Recent examples of this commitment include the new 3.0-liter inline-six with its composite magnesium/aluminum crankcase, and, of course, the 5.0-liter V10 high-speed power unit in the BMW M5.

In the development of new engines, BMW’s engineers carefully consider all parameters and components for their potential, at the same time questioning virtually all conventional principles. The result is innovative materials, new machining processes and optimized procedures in production. The BMW customer, in turn, receives far more powerful, lighter and cleaner engines that offer a significantly higher standard of fuel economy.

Efficient Dynamics: Overcoming conventional conflicts of interest.

Increasing engine output and torque while reducing fuel consumption, enhancing agility and nimble performance, and intensifying the experience of driving dynamics enjoyed by the customer: This is what BMW refers to as “Efficient Dynamics”, the guiding principle underlying all of BMW’s development and innovation. This applies equally to engine construction as it does to chassis development.

In a nutshell, Efficient Dynamics means consistently solving and eliminating conflicts of interest. In conventional terms, more power also means more fuel, more comfort means more weight, which again means more fuel, and so on. Particularly in the case of large luxury-performance sedans like the BMW 7 Series, solving such conflicts of interest is an especially great and demanding challenge.

BMW is able to escape this continuous loop through the use of intelligent materials and systems – for example, aluminum helps give the chassis and suspension of the 7 Series its light-footed, nimble behavior.

Chassis and suspension have been refined to improve both handling response and ride comfort.

The BMW 7 Series features an aluminum suspension which offers outstanding steering precision, exceptional agility and well-balanced driving characteristics. As a result, the chassis and suspension of the 7 Series combine superior agility and sporting performance on the one hand, with superior comfort on the other. In other words, it offers the best of both worlds.

The chassis and suspension of the 2006 BMW 7 Series has been updated and enhanced. The rear track is wider by 14 millimeters or 0.55 inches. Combined with enhanced suspension kinematics and BMW’s revolutionary Active Roll Stabilization, the 7 Series will continue to offer an unparalleled driving experience. For those seeking an even sharper edge, the Sport Package will again be offered with its unique suspension calibrations.

As a result, BMW offers the widest choice of suspension control systems in the luxury sedan segment, naturally also including enhanced brakes reflecting the higher level of power and performance.

Refinement in design: Even more sporting and dynamic, but with unmistakable presence and elegance.

The enhanced performance and dynamic qualities of the BMW 7 Series ensured by the new engines are appropriately reflected by suitable refinements in design. Apart from the new, striking powerdome in the hood, the kidney grille, headlights and front air dam have all been discreetly revised. The rear, in turn, is characterized by surfaces and body panels with even clearer contours, a new chrome trim strip, modified tail lights and the redesigned rear air dam. At the side, the more pronounced light contour in the sills emphasizes the enhanced sportiness and dynamic character of the BMW 7 Series.

In all, BMW’s luxury performance sedan preserves its powerful presence and clearly stands out on the road through its charismatic, elegant and truly unique appearance.

Inside the car, the unique feeling of luxury and peaceful tranquility has been further refined by the choice of materials and colors, with the control elements following the main lines of the instrument panel. So again, the interior of the 7 Series is now even more luxurious and sophisticated than before.

The iDrive control concept: Refined in its details, even more user-friendly.

BMW’s iDrive control concept, the ergonomically sensible combination of single-button control and display monitor introduced in 2001 and much copied since then, has now been further refined.

Optimized menu guidance in the Control Display, the upgraded presentation of menus, and direct access to the various entertainment functions – for example , one can now directly select audio source and radio frequency band – are essential elements of the updated iDrive system in the BMW 7 Series.

New features for extra safety, comfort, and individual style.

As of spring 2005, the BMW 7 Series is available with an even higher standard of series equipment and individual options for customizing the car:

All BMW 7 Series now feature BMW’s two-stage Adaptive Brakelights: Whenever the driver applies the brakes harder than usual, motorists following behind are warned by the larger brake light area.
The optional CD changer is now MP3 CD-capable.
The standard BMW Assist telematics service now includes Bluetooth hands-free phone capability.
Last but not least, the updated BMW 7 Series offers the customer a choice of four new paint colors, four new upholstery colors, as well as new 18-inch wheels on the 750i and 750Li.
The most successful BMW 7 Series ever.

Accounting for almost 160,000 units delivered to customers worldwide, the fourth-generation 7 Series is the most successful prestige luxury performance sedan in BMW’s history. Since its introduction to the world in 2001, the current 7 Series has already outsold the former model by almost 8 percent. And with customer deliveries of 57,899 units worldwide in its most successful year so far, 2003, the current BMW 7 Series outperformed its predecessor in that model’s best year (1997) by almost 14 percent.

In Germany, the BMW 7 Series became the sales leader in the luxury sedan market in 2004. Sales have shown impressive growth in Asia, the Middle East, Eastern Europe, Oceania and Africa where, compared with the former model, sales of the current 7 Series have more than doubled after 38 months in the market. Sales volumes in those regions are catching up with the markets where, by tradition, the BMW 7 Series has always had a strong position – in particular, Europe and North America.

In the United States, the success of the current 7 Series is unparalleled. In its first three years, it outsold its predecessor’s three best years by a significant seven percent.

Accounting for more than 50 percent of total sales, the BMW 745i/Li with its large V8 power unit has been the best-selling model worldwide. The long-wheelbase version, in turn, accounts for more than half of all BMW 7 Series sold.

The BMW 7 Series combines two cars in one: On one hand, it is a genuine BMW offering those typical BMW virtues such as driving pleasure, agility and nimble handling for the customer who enjoys driving. On the other hand, it is a highly prestigious luxury sedan offering generous space and comfort for the driver and passengers.

More than any other car on the market, the BMW 7 Series offers that Sheer Driving Pleasure so typical of BMW not only in the classic sense, but also in the extended sense of being driven. It is indeed this perfect combination of two worlds that the BMW customer opting for this luxury performance sedan appreciates so much, making this model the most successful 7 Series ever.

The J.D. Power & Associates 2004 APEAL Study (Most Appealing Premium Luxury Car) and the Strategic Vision Total Delight Index (Best Luxury Car, two years in a row) affirm that 7 Series owners love their cars. The 2006 BMW 7 Series will give them more to love.

New V8 engines combined with numerous other enhancements will ensure that success of the BMW 7 Series will continue with the 2006 model.

BMW.Williams F1 Team 2005 Stats and Facts


On a Grand Prix weekend, the race team is around 100-strong, with 70 staff from WilliamsF1, 20 from BMW and another ten or so responsible for tasks such as catering.
The test team for two cars fielded in a GP event averages 60 people (40 from WilliamsF1, up to 15 from BMW, plus five catering staff).

WilliamsF1 takes around 25 tonnes of material to each Grand Prix, including spare parts, tools, wheels and pit equipment. In addition there are at least three chassis and, for exceptional circumstances, the team is even equipped to assemble a fourth racing car. For European races, the freight is distributed between two transporters and two trucks which remain in the paddock, as well as a motorhome.

BMW packs up around six tonnes of equipment for a Grand Prix event. This included six engines as well as tools and spare parts. BMW has one transporter, a truck for the technicians and a motorhome.

The team uses 16 large HP computers at the track along with 26 HP notebooks and 100 radio sets with headphones.
500 meters of data cables and 300 meters of electric wiring are hooked up for the BMW WilliamsF1 Team at each race.
A team consumes up to 1,200 liters of fuel per GP weekend, between 60 and 80 liters of engine oil, and up to 30 liters of gear oil.
At a hot race, counting set-up and dismantling, the team and its guests consume some 3,300 liters of mineral water and soft drinks.
In 2005, eleven sets of tires will be available for each car over the entire race weekend.


250,000 working hours are needed for the design of the chassis.
A further 250,000 hours are required for its manufacture.
It takes two days to build an FW27 from a bare chassis to a fully rolling car.
Approximately 4,500 drawings have been generated by WilliamsF1 in the initial design of the FW27, with a further 4,000 expected for developments during the season.
WilliamsF1 produces around 200,000 individual components each year.
Cars are re-built between every Grand Prix. This involves fully stripping down and servicing the fuel system, hydraulics, steering, gearbox and electrical systems. In addition to this all the composite and metallic parts are inspected and crack checked for damage.
The FW27 car is the lightest car produced to date by WilliamsF1 at the Grove factory. Even with the restriction on regulations, the ballast level has increased over that carried in 2004. When ballasted up to meet the FIA weight limit, the FW27 weighs 600 kg.
The top speed of the FW27 is expected to be approximately 375 kph. It will only see this speed at Monza in Italy. The lowest top speed the FW27 will reach is 290 kph at Monte Carlo, where gearbox ratios are specially selected for the tight and twisty street circuit.
Although Formula One regulations continue to restrict aerodynamic development, the FW27 generates enough downforce to drive upside down through the tunnel at Monaco.
The FW27 has a six speed gearbox that will change gear 2,800 times during a Grand Prix (In Monaco this figure rises to 3,100). Running at temperatures up to 150 °C requires advanced materials technology to withstand the heat and loads.
FW27 control systems include hydraulically assisted power steering, electro-hydraulic gear change, differential and clutch as well as the electro-hydraulic throttles and trumpets on the engine.
The FW27 has a sophisticated traction control system that enables the driver to apply the throttle earlier than normal as the electronics on the car can control the tire slip faster than the driver. It differs from the systems used in road cars where the primary task is to induce understeer to make a road car stable and easy to drive.
Carbon brake discs and pads are used on the FW27 that generate surface temperatures in excess of 1000 ºC during braking events up to 5g of longitudinal deceleration. The FW27 can generate lateral accelerations up to 5g during cornering.


More than 200 engines left the BMW Formula One factory in 2000, 2001, 2002 and 2003. Though the number dropped in 2004 following the new regulations, the total still came close to 200 units.
The BMW engine consists of approximately 5,000 individual parts, including 1,000 different ones.
It takes around 100 working hours to assemble the BMW engine.
More than 1,000 CAD drawings were produced for the BMW P84 engine for the 2004 season.
The BMW P84 engine weighed around 90 kilograms.
With the P83 engine, BMW achieved results in 2003 never before recorded by a Formula One V10 power unit. The P83 had an output of more than 900 bhp and a peak engine speed of 19,200 revolutions a minute. For the races, the speed was limited to 19,000 rpm. Although the regulations for 2004 doubled the distance, engines had to last an entire weekend, these values were again achieved by the P84.
In 2004, all BMW F1 engines underwent revision at intervals of 800 kilometers.
In the P8 4, maximum piston acceleration was 10,000 g. Peak piston speed was 40 meters per second, or to put it another way, zero to 100 km/h took 0.3 thousandths of a second. The conrod was subjected to forces approaching three tonnes. In more graphic terms, this is equivalent to two BMW 5 Series road cars being hung onto the conrod and removed again 300 times a second. A Formula One titanium conrod weighs 295 grams. By comparison, a steel conrod from a three-liter BMW production engine is larger and weighs in at 545 grams.
At 19,000 rpm, 316.7 revolutions and 1,583.3 ignitions take place each second in the BMW F1 engine. 9,500 engine speed measurements are made, the pistons cover a distance of 25 meters, and 550 liters of air are drawn in.
The exhaust reaches temperatures of up to 950 °C, and in the pneumatic system the air temperature rises to a maximum of 250 °C.
At an average race distance of 300 kilometers., the BMW engine experiences around eight million ignitions per Grand Prix (800,000 ignition processes per cylinder).
When the car returns to the pits during practice or qualifying, oil samples are taken and subjected to a spectrometer analysis in the pit garage. The metallic traces in the oil provide important information on the condition of the engine.
The ultra-high-speed 130R turn at Suzuka is the greatest challenge to the oil system with its lateral load of 6 g.
Only in the Loews hairpin in Monaco does the engine speed in first gear drop below 5,000 rpm.
In 2004, engines endured the greatest full-throttle load in Monza, at 69 per cent per lap. It was there too that the highest speed ever achieved in Formula One was recorded, notably 369.9 km/h (Antonio Pizzonia in the WilliamsF1 BMW FW26 during the race).

A Formula One driver burns approximately 600 kilocalories per Grand Prix and loses on average two kilograms in weight.
The average temperature in the cockpit is 50 °C.
Drivers’ heart rates reach peaks of 190 beats per minute during the race.


A Formula One car can accelerate from standstill to 200 km/h and back again in under seven seconds.
The 0 to 100 km/h sprint is achieved in around 2.5 seconds by a Formula One racer.
Acceleration from zero to 200 km/h takes less than five seconds in an F1 car, which is equivalent to 140 meters
Full braking from 200 km/h brings an F1 to a standstill in 55 meters, a process that takes 1.9 seconds. Deceleration forces during this can amount to 5g. A driver with a body weight of 75 kilograms is pressed into his seat harness with a force of 375 kilograms.
Formula One tires reach temperatures of around 100 °C.
