The problem with my Style 42's is the offset. It's 20 and the e36 needs an offset of 35-40. Since I'm not getting many offers to sell them I going to go to a machine shop and see how much it would cost to have them make some 15mm thick rings that I can put between the centers and the barrels on the lip that the centers normally get attached to. That will push the barrels/tires in toward the center of the car and create a 35mm offset. The bore will still be 94mm but i have hub centric rings for that. I'll need longer bolt to attach the centers to the barrels. Hopefully its all going to be cheaper than plunking down $400-500 for another set of rims with the correct offset.

It all sounds logical enough...am i missing something?

why would you spend that much money to "fix" a wheel that doesn't need repair? So many guys are running et20 its not even funny. Get a smaller tire size, or roll/pull your fenders, buy some spacers if you need them depending on your suspension set up, and save your money. Guys run style 5 et20 with lowering spring with 205/40/17 with fender rolling and have no rubbing issues

I think his reasoning is so that he doesn't have to run a 205 with camber and rolled fenders.

I am very interested to see how this turns out if you go through with it OP

So you're saying I should spend another $200-400 for used/new tires? and then roll the fenders? I appreciate the comment but that sounds like a lot of money and work to accomplish the same thing as changing the offset. You may be right though. The bolts to do all four rims wont be cheap. It doesn't cost anything to ask a shop about the rings.

what size tires are mounted on the rims? a fender roll is fairly inexpensive, and you might not need it in the first place, it all depends on what your suspension is. Are you lowered? and if so with what? if your stock height you really shouldnt have a problem. How wide are the style 42s?

The rims are 8x17 all around. I would do better with 7.5x17 but that's not what I have. The tires are 225/45/17. I was told by a couple guys who have Style 5's that's what they run and no rubbing.

The car is not lowered. its stock height with Bilstein Tourings all around. If I can't make this work then Ill just pickup some Style 42 reps that have the correct offset. Ive seen complete sets for $450 shipped to my door.

stock height you wont have any problems at all! guys slammed are still running 215/45/17....and 215 on a 8" wheel is BARELY a stretch...i run 225 on and 8.5" rim and its not a huge stretch at all.. read thru this thread

http://forums.bimmerforums.com/forum/showthread.php?t=1098395&page=21

just mount the wheels and save yourself some money. Once theyre mounted go for a ride and you should have NO problems...if you do come back and tell us and we can go from there. Its gonna be expensive to get the offset changed, trust me, i know

I looked at that thread and all those guys are about 2mm away from the rear fender sitting on top of the tires. I mounted mine a few days ago and the smallest bump makes the rears rub on the very edge of the tread. I mean the very very edge. So I need to lose about 1/2" to make them not rub. 3/4" would be better. A fender roll will get me about 1/4"

Just the raw material a machine shop would need to get started will cost as much as getting 4 new tires. They'll have to buy 4 sheets of aircraft quality (6066-T6 for example) that are 1/2" thick and 18" square. By the time they do the layout and the CNC program and add in the machine time you're going to be into this $1500-$2000 easy. This is IF you can get them to take on the liability of making a custom part that could affect safety on a car.
I'm running 225/50 x 16 on style 30s with 20mm spacers (close to same offset as E39 style 42s) without any fender rubbing issues and your tires are .25 inches smaller diameter than mine. What condition are your rear shocks in? Sounds like you're getting a lot more suspension movement than I am......

I'm really interested in this because I'd like to see this work out for you AND I've been looking for some style 42s myself.:)

fender roll/mild pull would get you plenty of clearance... I had my rers rolled by a local guy for 60 bucks... youd be surprised how much a roll gets you

fyi, I'm running a 17x10 et 16ish with 215/40 in my rears.... with a healthy roll/pull. 97 328i 4dr. slammed on coils

This.

Is there enough "meat" on the wheels where you could possibly have the rear of the wheel where it mounts to the hub shaved down any? If so I would look into that

I was going from memory when I estimated the cost of the raw aluminum. Just out of curiosity I checked and my estimate was way too low. For a 24" x 24" x 3/4" 6061-T651 aluminum plate the cost is about $275 and you'd need 4 of these to have your spacers cut. You're probably looking at another $2K to get the machining done, and you still have to find a shop that will do it knowing what it will be used for.

CJRUCK , I think he's going to have the same problem getting a shop to take on the liability of modifying a wheel that he's going to have getting them to make his spacers......

^^^ this +1 ^^^

Interestingly my 42's are ET47 ( 8inch 225/40/17 ) and fit like a charm, front and back are ( tucked ) under the fender lips with NO rubbing whatsoever.

Seems like there are some E36 offset style 42s out there but they're pretty rare. Most that I've seen are E39 22 offset.

NO this would take material OFF the rims and make the offset even lower. I want to ADD material. to move the barrels in toward the center.

as for the cost of the rngs? I thought about that and realized it wouldn't be cost effective to have them make 4 complete rings. I was thinking about 2 pieces for each ring.

Sounds like I'll be looking for a fender roller if I don't sell these.

No, taking material off from the hub will raise your offset. It is the reverse of adding spacers.

I run 215/45/17 and I'm lowww. Its not the fender lip that rubs its the inside of the fender if I have people in the back. This is a pic with the front jacked up. You can see the tire missing the edge and hitting the top arch

Just find a friend with a roller fly :) if you were close by one of my friends has one.

ET 20 with 225/45 should be fine on a stock vert. Just make sure to take your time and use a heat gun.

I'm running 225/45 on ET 15s (on the beater)...even worse than you. Took a bit of rolling but it's good now.

+1. you'll need to hammer it flat, then roll

p.s.

I thought the answer was going to be 'I found a 5 series!'... ;)

+1 on the fender roll. It's been done a ton, and doesn't cost what it would to have one rim changed to your offset. It might require new tires, but you'll still be cheaper doing it that way. Sorry to make you jealous, but I picked up a set of style 42's last summer that I'm just starting to refinish, but they're E36 offset (staggered) from a Z3. Got the first 2 done on Saturday. :buttrock

I'm jelly! Those are exactly what I've been looking for!

Flyfishvt - splitting it into two will help a bit on the raw material cost but it's going to make the machining harder which may raise that cost. I don't think there's any way you're going to get the cost of the custom spacers below the cost of buying some new replicas and tires.

I've heard that you can buy the rings to correct the offset idk were though just something i've heard.

Just take it to said machine shop and see if they can shave 5-10mm off the back

NOPE I decided to roll the fender until I can sell these. Ive had 4 offers so far. 2 local and 2 "not so local". If the fender roll doesn't work well enough I'll get style 42 reps with the correct offset. It'll mean plunking down another $75 to get the tires swapped over but I'll have brandy ass new rims that fit.

Thanks for all the advise. Its supposed to be nice weather this weekend. All I need is a fender roller. Cant seem to find one to rent anywhere. VT isn't exactly full of low riders and wide stance cars.

look on ebay. i just got one for $98 here in australia. im sure you'll find plenty in the U.S. besides, when you buy one.. you will always have one. but its up to you.
hope it works out will, and dont damage the paint :eyecrazy

ET is the distance from the mounting surface of the wheel to the centerline of the wheel. It is difficult to measure at home.

If you have an ET of 20 on a wheel that you want to put on a car that takes an ET of 40, then the wheels you want to use will be further outboard than the same wheel with the proper wheel.

If two wheels are the same width, the one with the smaller ET will fit on the car with the outboard side of the wheel more outboard than the wheel with the higher ET. You do not correct a low ET with spacers that move the tires more outboard. In theory, you would have to bring the lower ET wheels inboard by using a rear end that was shorter -- obvious hurdles would make this financially impossible, or at least silly.

If the ET on a desired wheel package is greater than the specification, then the problem becomes that the inboard side of the wheel will strike the suspension components -- shocks, springs, control arms, and so on -- and the correction for this problem is to get a set of spacers to move the wheels outward.

I'm not sure, but I think you are looking at the problem/solution backwards. You have a low ET, and are seeking spacers as a remedy. What you need is to have the wheels machined from the back so that the ET is increased. This solution presents wheel-integrity problems that you surely want to avoid, but the solution moves the wheels in the direction they need to go in order to fit under the car.

Quote isn't working...but quoting JD.

He's looking at putting spacers between the wheel face and the barrel, not between the face and the hub. He has 3/2 piece wheels, so has another connection that he can vary.

I'm not sure how well it'd work, I'd be worried about adding 15mm to the length of the bolts/etc...but need so see them in person

ya fly i think you have you philosophy bassackward's.

0 offset = center of wheel close to hub, this equal's mexipoke stance

25 offset =would be 25 mm to the right of the center of the wheel. this et can work with our cars with correct tire sizes and fender work.

now 40 offeset if 40 mm to the right of the imaginary line so more of the wheel itself tucks inside the fender well.

you're trying to reinvent the wheel (no pun intended) and btw they are called wheels not rims.

rims= what gangstas put on their "beama"
wheels= for when you're putting new shoes on the bimmer

Moron95M3
05-15-2012, 03:46 PM
actually you're not understanding non 1 piece wheels have the abillity to be spaced not only at the WMS, but at the barrel.

Reread his first post, if he moves the barrel of the wheel inboard via spacers then he gets a higher offset ;)

Fly's no dumby guys


take a look at this (awesome section view IKR!):
http://a6.sphotos.ak.fbcdn.net/hphotos-ak-ash3/540226_747253920057_6607892_34275502_347051029_n.j pg

If he puts spacers between the black barrel and the red wheel face, then his offset becomes more, as the barrel gets spaced inward.

make sense?


Fly, still not sure if I'd put that type of moment load on the wheel bolts though...

JDStrickland
05-15-2012, 04:26 PM
I get it. He wants to take out the 20 (whatever) screws that hold the bead to the center section of the wheels, and put a spacer in, and then put in 20 new screws that are longer. That might work... Seems more expensive than buying wheels that actually fit, but I see what he's trying to do.
