Surprisingly, the dealership replaced it all under the maintenance warranty w/o even a comment about how they got that way (or why I'd triggered the 'don't drive it' warning about 200 times). I put on the accessory BBK kit, so I'm stuck w/ 18's - a great set up, but if I'd been able to find a stock 340mm set I'd have preferred to keep the option of 17's, especially for the track set.

Install on the belts was very simple (and totally worth it), once I got over the fear of just pulling up on the back seat bottom. I kept waiting to find out there was a hidden bolt and i'd f'it all up, but it really is snap-in-place, no need to remove front seats or a/t complicated (you also need a huge Torx driver - 40 or 45mm). I did have to bend some of the mounting plates in the vise, but it wasn't difficult, could probably do it with a couple of vise grips, or a hammer and a solid corner. If the 1'er version has different mounts, they can probably sell you the attachment ends separately. You will want to keep the paperwork with you for tech inspection - I had one tech inspector who initially felt they were unacceptable b/c no sub strap, until I was able to explain the 'breakaway tab' that lets them work like a 3 point in a crash (don't call them 'a harness' and make sure to clarify that they are OEM/SAE compliant and work just like a 3-point in a crash). In the meantime, do you know about 'the belt trick'? - you set the seat a few inches back from ideal, then hand-snap the 3-point until it locks up; keeping tension so it stays locked, you then slide the seat forward until belt is tight on you, and it will usually stay that way thru a session. It takes some practice to find the right distances, but much better than a loose 3-point.

which quick fit harness did you get for your F22? do all the existing stock belt buckles still work or did you have to swap stock buckles to get the quick fit to connect? I was under the impression that we had to swap buckles for our cars and then the stock rear seat belts would no longer work since they won't be able to plug into different buckles?

I think I used the E82/E92 version; if I can find the paperwork I'll update this to verify. It does work with the stock seatbelt buckles, but you need to install 2 additional male ends for the outboard front and rear (these have a fitting so you use the stock belt attachment bolts - took me less than an hour). They don't interfere with using stock seatbelts when the harness is out of the car. Certainly one of the best mods for driving on track, well worth it at twice the price.

excellent. thanks. if you find the paper work let me know.

I have a friend that had harness for his 1 series which he sold so I grabbed the harness. A track day popped up due to warm weather here so put the summer wheels back on. I didn't think I had time for the harness install but for the heck of it I did a quick tug on the rear seat and it popped right out so went and installed the harness. Beautiful German engineering. Worked great. Just have to remember to close driver door before snuggling in. Great track day.

I would like to play with my E36. I spend lots money on my 228i, it's make me so disappointed. I have stage 2 tune, trans tune, full bolt on engine, f82 LCA, bushing, bilstein b14, camber plate. But it is still too slow. I'm rather than spent these money on my e36 to make it a lot more faster than my f22, and save money.

I own an M240i which I track. The 230i cars seem to handle curvy tracks such as Virginia International Raceway better than the M240is. I think their weight balance is closer to 50/50 than that of the M240is.

Curb weight is the major handicap our cars have; it's hard to be really quick while accelerating all that weight.

APEX happened to be debuting a forged line with that exact fitment available, and I've long admired their quality and commitment to the BMW market so I was happy to be the first name on the list on day 1. I probably could have gone with the flow-formed version, but forged weighs less and is stronger for when my dumb ass runs over cones, speed bumps, and Nevada's crater-like potholes, and being an early adopter yielded a pretty serious discount that kept the costs in check.

"Phase 1" - fixing the easy stuff - Done
- 255/40-17 Bridgestone RE71R's
- 17x9 et 42 forged APEX Arc8-R's
- APEX 5mm front spacer

Can you share some more pictures on your fitment ? No rubbing on full lock steering ? Did you have to roll the fenders ?

I'm looking to get 255 on my car as well ( currently on 235 ) and still looking for that "ideal" ET.

Sure thing, here ya go. Inner fender lip is rolled (but not pulled). No rubbing. I won't be able to take more pictures until spring...I've got the stock wheels with winter tires on right now.

Yep...I just re-confirmed this myself today with HMS...they're still "thinking about" having a specific F22 / F87 QuickFit harness available but holdup is all the required "testing" to certify for these BMW models. I think I'll order the E82/E92 QuickFit version which many have said DO fit albeit not certified.

It works great. I also got the anti-submarining belt kit which works with it. Haven’t installed yet but many experienced drivers have been arguing the absolute necessity for it in conjunction with the 4 point. Looks easy enough to put in — I haven’t seen anyone on here post about that part yet so I will report back soon after installing.

Do you have a link for that product? I can't seem to find it on HMS' site.

It took me awhile to find the first time I was looking. It should be able to go right up through the stock sport seats no problem. I’ll know for sure by next week when I get time to install.

Thanks!

It would be great if you could post some installation photos.

[PeanuKeeyes]

Will do! — hard to believe it’s almost time to get back out there again. I feel like I don’t understand how time works anymore.

Time flies, sure does.
So is this the harness you’re using?

https://www.schrothracing.com/item/s...ning-Harnesses

Be great to see some pics.

I’ve done 2 light track days in my m240i using only a Hans device,
Simpson Hybrid Sport. It’s great, but I’m flailing all over the place.

Yeah, that’s the one. Be sure to add the harness grips to the order. I didn’t last year and it’s a true pain to loosen the straps without them. I haven’t reinstalled the harness yet but I will be soon to fit the sub strap next week. I’ll post pictures when everything’s back in.

I had feared that these would cause spinal compressions as my shoulders come up over the seat-back, however, upon further investigation, they are designed in a way to release slack on one side and sort of act like a regular seatbelt on impact, so it shouldn’t be a problem. Still, to echo what’s been said here already, it’s not certified for our cars. Personally, I’d rather roll the dice over being tossed around like a rag doll.

Edit: I edited this in the comment below but just to be sure, the harness is actually the Quick Fit "Pro" -- this buckle has the receiving end for the additional sub kit. https://www.schrothracing.com/item/schroth-quickfit-pro

That pic is the Quickfit; there is a QF-II that has a better buckle, same basic design otherwise (doubt the subs would work with what was pictured). They don't really need a sub belt, but it can't hurt.

Check the M2/3/4 boards, as there are often used sets for sale b/c the M-seats don't have the hole to use these ):

And perhaps it is a promising sign of upcoming certification that they are using a picture of a 2'er to illustrate street legal harnesses (https://www.schrothracing.com/post/s...egal-harnesses)

Good catch!
It’s the Quick Fit Pro, https://www.schrothracing.com/item/schroth-quickfit-pro

This is what I have, and there is a hole in the M sport seats, you just have to remove the piece of leather/pleather between the front adjustment and the seat bottom. I plan on using Velcro to make it a quick process to remove and replace. Pics to come next week.

[fatsport]

Thanks guys. Quick fit Pro stated it was to go with a Hans device, so that makes sense.

The E82/E92 harness? Dimensions for our car are basically the same as the 1 series(E82), so I think that should be it.

My next track day is with SCCA at Palm Beach Raceway on March 28th, so I can order 1 if I don't see it on the boards for sale.

[PeanuKeeyes]

Update on the Sub kit add-on.

Maynard was right, the seat is solid under the front bolster! Can’t believe it — usually seats like these have a gap there under the fabric but these have a solid metal plate design. So I’m sticking with the 4 point after all. The guys who told me it was necessary, didn’t realize I have the QF “Pro” with the benefit of the relief strap design, so that was the reason I was being nudged towards needing the sub kit. I guess we’re all good without it.

[AmuroRay]

Can you show how you installed it? I have one from my E92 I could use.
