    Review: Cobra Nogaro seats (uniquely street friendly fixed back bucket seat)

    I am just going to start with pictures, because I know everyone is going to skip to that either way. Please read on, after, as there are a ton of very specific reason why I think this seat is THE best seat on the market for cars that see track and street use-- and quite different that other offerings currently on the market.





































    Pretty spectacular, in my opinion!

    Seats are a project I have been pondering doing on my car for over a decade. In that time, I’ve run a bunch of different seats in different cars (specifically Sparco Evo IIs, Recaro SPG XLs, and Recaro Pole Positions) and found them all to be unacceptable in a street driven car for a variety of reasons.

    I view my car as a tracked street car. Every modification I do to it is done with that priority set in mind. That means I am not willing to do anything that makes the car less safe on the street (which lots of track focused seats do), less practical, or too much of a pain to hop in to go grab milk. In the context of seats, I want to improve the car on track as much as possible, without making it worse on the street.

    I also do not want to do anything that degrades the quality of the car. One of my favorite things about the M3 is that it is a high quality, well made object, which uses premium materials.

    Safety
    My primary concern was not making the car less safe on the street. There are two areas where traditional aftermarket seats negatively impact street safety.
    1. The factory 3 point receiver has nowhere to go. This is well exemplified in this picture of the Recaro SPG XL mounted in my M3 wagon (since removed):





    Using the factory 3 point receiver, you have to choose between pulling the belt over the top of the side of the seat (which creates a gap between you and the belt—unsafe) or feeding it through the hole—which causes it to jab into your side continuously and be orientated off the load path of the belt. A common solution to this is to run a back seat receiver in the front, but doing so comes at the expense of the factory belt pretensioner functionality, as well as the seat belt buckle sensor. Factory fixed back seats address this by coming either with low sides, like BMW did in the CSL/CRT, or with cutouts specifically designed for the seat belt receiver, like Porsche does with their factory buckets or BMW does in their GTS cars.


    CSL seats


    CRT seats


    Porsche’s every modern car CF bucket


    M4 GTS factory seats


    If you look at the Nogaros, you will see Cobra went the same route as BMW did with the CSL—the sides are low enough in the seat belt receiver area to allow the belt to pass over the seat, unobstructed. I don’t know of any other fixed back seats on the market that play nicely with the factory 3 point receiver.

    2. Many aftermarket fixed back seats have little to no head padding. This was true of the Recaro in my wagon above, and the Evo II I ran in my track car. For race/track use, where you are wearing a helmet, this is fine. For street use, if you get into a crash where you hit your head on the head rest (which is pretty much any front or rear end crash), it is a serious safety issue. Again, if you look at the pictures above, you’ll see that factory fixed back bucket seats always have head padding. On aftermarket seats, this is pretty unusual!

    3. The Cobra Nogaro is the ONLY fixed back seat on the market that is approved (by Schroth) to be used with a Quickfit harness. This is a huge improvement in on track safety over the factory 3 point in all crashes, and allows for the use of a Hans device (enabling further safety).

    4. For reasons beyond my comprehension, many fixed back bucket seats place the harness pass through holes too low to safely use, for an average sized person. It's like they're designed as a styling feature rather than an actual safety feature. The Nogaro does not suffer that-- no spine compression from too low harness holes here!

    Comfort

    1. The Nogaro has considerably more padding than any other non factory bucket seat that I have experienced (I’m starting to sense a trend here). This makes it more comfortable to sit in for an extended period of time. That said I had Cobra make me an extra thin bum cushion (that was there terminology for it on the invoice) specifically for track use—allowing me to sit lower, and have the side bolstering be higher relative to my body.
    2. The lower sides (which, again, I have only seen on factory fixed back seats besides these) mean ingress and egress are considerably easier. You do not need to have a strategy for getting into and out of the car—you just sit in it, and get out when you are done. When I had the SPG XL in the M3 wagon, my wife refused to drive the car because of the entry exit procedure. She prefers the Nogaro to the stock seats
    3. Adjustable lumbar-- In a fixed back bucket seat, installed by Cobra, at the factory. Different people need different amounts of lumbar support, and lumbar support is hugely important to how comfortable and supportive a seat is.

    Customization

    1. Starting with the obvious, mine were done in Imola leather with Imola thread. This was done by Cobra, at the Cobra factory, on their standard production line—meaning it is 100% factory quality/fitment. Cobra has a number of leather options, and is adding more, but, based on samples they sent me at the time, none were the 100% match to Imola I was looking for. I ended up getting samples from ~15 different leather suppliers before I found one I was happy with (thanks to a recommendation from Braymond141): Relicate. https://relicate.com/ . My experience with other seats makers has always been that they are not willing to work with you at all—any customization has to be done after the sale, by a 3rd party shop—more expensive and likely not as good as factory.
    2. Thread spacing. I actually didn’t even think of this on my own—it was Cobra’s idea. They had me take a picture of a tape measure held up against the stock stitching, and then matched it when sewing the seats—meaning the stitching on my seats has the same spacing as the stitching on the door cards/stock seats. A small detail, but also completely awesome, in my opinion!
    3. Factory BMW e46 seat heater pads are installed in my seats (also installed by Cobra)! This means they are plug and play with the factory seat wiring harness, and work with the factory seat heater controls in the center stack. Great for brisk spring/fall track days, first thing in the morning, with mandatory windows down!
    4. Extra, thin bum cushion. I had Cobra make me an extra bum cushion (their terminology) which is just a piece of neoprene—wrapped in Imola red leather, with BMW seat heater pads. This allows me to sit lower and have more side support while on track, similar to a more track focused bucket seat.
    5. Seat occupancy sensor. This is something I didn’t choose to do, as the BMW occupancy sensor tends to be unreliable, but something they were willing to do (so I thought I should mention if others wanted it)—they were more than happy to install this, at the factory, as well. I opted to not get it, and coded the errors. The downside to my approach is that the passenger airbags will go off in a crash, whether there’s a passenger in the seat or not—making a crash more expensive.
    6. Adjustable lumbar support. As mentioned above (in the comfort section), I have adjustable lumbar support in my seats. This can be adjusted on the fly by a small hand pump/release valve that I have tucked inside the leather on the tunnel side.
    7. The shells are offered in GRP (22 lbs seats) or CF (12 lbs per seat). I opted for GRP because of the price difference… which I might regret one day (I could have had an additional 20 lbs of weight saving with no detriment to functionality/comfort).

    Mounting

    1. Brey Krause has an upcoming line of Nogaro specific mounts for the e46 (as well as 911s, Caymans, e9Xs, F8Xs/F3Xs, and some other cars), which attach to the factory BMW sliders. Having car specific, seat specific mounts gets you as close to a factory optimized seat setup as you’re going to get. My car was the development car for the e46 mounts, so the version pictured may not be the final production part—but it should be close. I choose to run a power slider on the driver side, for precise adjustment and because it lets you get the seat lower, and a manual slider on the passenger side, for faster back seat access.
    2. The Brey Krause side mounts use the factory sliders. Unlike aftermarket sliders, the factory sliders are designed to have seat belts mounted above them—which means the seat belts stay properly located to your body, regardless of seat position (including sub straps, using the Brey Krause sub strap mounts for stock sliders—R-9228 and R-9229). For my car, I went with the factory e46 sedan/wagon sliders, as they add an outboard lap belt mount point (unlike the coupe’s sliders). While this wasn’t necessary, as the Brey Krause lap belt kit (R-9225) can add a lap belt mount point to the coupe sliders, I like factory parts.
    3. Using the factory sliders also means the factory 3 point belt receiver on the slider is retained. This means the pretensioner functionality is retained, as well as the “seat belt not buckled” sensor—all of which also goes through the factory seat plug.
    4. The factory BMW sliders have ~double the travel of aftermarket sliders. This makes the back seat still useable, both for people or for loading track tires into the back seat.
    5. Using the factory slider means no Swiss cheese adapter plate is required—the slider just bolts to the floor of the car, just like stock.
    6. Slider slots: The Cobra Nogaro has another unique feature that I have not seen on any other seats—slots in the seat base, that would otherwise be wasted space, to clear the slider. This means the seat can be mounted lower in the car before it runs into interference. As someone who is 6’4, with most of my height in my Torso and often wearing a helmet in the car, this is a huge win for me—this seat will allow me to be in the car without a reclined seat for the first time, ever! I can actually fit an entire fist over my head while sitting in the car, now.




    E46 Manual slider with seat installed, with Brey Krause R-9227 manual slider release handle.


    E46 Power slider without seat, with sub strap mount showing. Slider is controlled by an e30 window switch—I grabbed a factory e30 window switch wiring harness from an e30 that was getting parted out for an OE plug install. All wiring goes through the factory seat plug, so installing/removing the seat is as easy as with the stock seat—one plug for everything.

    Weight savings
    Excluding the fire extinguisher, but including the mounts and sliders, I saved 59 lbs—almost exactly the weight of a stock power/leather seat! I did get the GRP buckets—had I ponied up for the carbon buckets, it would have been another ~20 lbs of weight savings. Perhaps equally importantly, the setup lowers the COG. Most of the weight of the seat setup is in the base of the seat (side mounts, sliders, seat base). Additionally, my seating position is a couple inches lower than stock—not an insignificant amount of weight to get mounted lower!

    Driving Impressions
    Driving in the Nogaro is very similar to other fixed back seats, if you have experienced that. Having your seat bolted directly to the car, instead of sitting on box spring, means you’re much more in touch with what the car is doing at all times. Having a competent suspension becomes more important, but in exchange you are provided with more information about the cars behavior than you could even get from a stock style seat. The seat also holds you in place far better than stock, which means you spend far less time bracing yourself in place and far more time focusing on driving the car. Having a bucket seat doesn’t make the car itself notably faster, but it does enable you to be a faster driver. On track, no contest compared to a stock seat—at no point am I fighting to hold myself in place, as you do with stock seats. They aren’t as supportive as a dedicated race seat, but they almost are—without the huge street tradeoffs associated with a race seat.


    Conclusion
    This post went on longer than I planned, but seats are a project I have been pondering for years. I wanted to fully flush out how I ended up, where I ended up.

    The Cobra Nogaro occupies a unique place in the market, with several benefits over competing seats that are not immediately obvious. For a car that still sees street use, I believe they are the only non OE fixed back bucket seat that comes without significant compromises. The Nogaros gets you 90% of the benefit of a traditional race seat with almost none of the tradeoffs normally associated with a fixed back bucket. Additionally, they’re 100% made in Great Britain—no Chinese parts here! It is the only aftermarket seat that is made with the same priorities that the car manufacturers use when they do fixed back buckets for street driven, track designed cars.

    During this process, being the PITA customer that I am (take me to the source!), I’ve fostered a good relationship with the owner of Cobra and the guys at HMS (the US importer for Cobra). If people are interested, I’d be happy to try to organize a group buy on these. Cobra’s racing buckets seem to be quite popular in the club racing crowd, but the Nogaro seems to be almost unheard of in the USA. Given the Nogaros unique feature set, I think this should change. A group buy could be an excellent way to kick them into gear!

    Yes sir. As you saw, it didn't bring any responses. Maybe in this sub-forum we'll at least hear about fixed back seats/no roll bar safety issues.

    Ha, someone should tell BMW (e.g. the csl), Porsche, etc, who offer that setup stock in every county other than the USA.

    Only in the USA do people have this weird conception that that’s an issue.

    I think they would if installed on e46 sliders— which should fit, based on me running e46 sport seats in my e36 M3 street car, on e46 sliders, back in the day.

    awesome post. Very detailed and those seats look great. Brey Kraus has an awesome solution with the factory slider side mounts... and yes they should work on E36 as well.

    Could end up being a very popular model for the tweener cars.
    Nice post, very detailed.

    Jeez but that's a beautiful end result. Show car quality, just stunning.

    Talk about a well-trodden path!

    A very well known and reputed US-based racing safety equipment expert explained to me a number of years ago why the old argument about your head and neck becoming the roll bar when the occupant is in a fixed back seat with harnesses in a car without supplementary rollover protection is overblown. Turns out that the more common risk in rollovers is neck injuries from dropping out of your seat onto the roof while the car is inverted. That's a much more likely scenario with 3-point seatbelts, and quite unlikely with harnesses.

    Oh, and for these purposes it doesn't much matter whether the seats are fixed back or stock reclining. Contrary to often repeated paddock/urban myth, stock reclining seats are not designed for their seat backs to collapse in an accident. What the hell good would that do? To the contrary, they're designed to stay where they are so that the 3-point seatbelt can keep the occupant in place.

    Hi Neil!

    I bet it was HMS and/or Schroth you were talking to? They’re pretty clear that this is a safe setup, in their tech tactics pdf on how to safely set up a car (and that a lot of the conventional wisdom floating around is just false):
