M competition wheels on Supra?

[jleggette]

I understand the supra has a different bolt pattern and all was just wondering if there were any conversions out there as I was really interested in doing this swap myself. Didn't even see any renders out there.

Well depends on which wheels you're talking about. Because now modern BMW's (G numbered), are also 5x112 like Supras, as opposed to the 5x120 it used to be.

So the wheels from the Z4 M40i, G80/G82 M3/M4, G30 M5, G15 M8, and even the upcoming G87 M2 are all compatible bolt pattern wise - pending calculating the need for spacers or wheels being too small/large to run.

Let's assume you go for what seems to be the most popular and well known, the M3/M4 Competition wheels, in this case, the 826M model in either Bi-Color or Black.

Those are 19x9.5+20 front and 20x10.5+20 rear. Not totally out of the realm of possibility for Supra fitments. You could even run the fronts square with 275/35R19 and maybe add a spacer in the rear.

Currently, some people have mixed success running conversions for 5x114.3 to our 5x112, but YMMV.

I'm less concerned about the wheels, but I want some OEM big brakes

Thanks for the info! I wasn’t aware the current gen was the same. I’m gonna look into a square stance for this as it’s something I’ve been eyeballing for a while. As the other guy mentioned a BBK swap would be nice too but probably would have to check out custom bracket fabrication for that.

@tru3sight on Instagram did it, looks pretty good IMO

I would hold off on the brakes - maybe before the car is gone in 2025 they will give it a big brake option and you can just buy them for a straight swap.

I'm still surprised someone hasn't fabbed up swap brackets to support any one of the many cheap Brembo kits from GM cars. There are some extremely capable used setups for under $1k.

Corvette C7 is 6-pot front, 4-pot rear, monoblock and you can get a full set shipped for $1100 on eBay. One of many examples.

Exactly!

Most of the rear calipers won't work because of how our e-brake is setup and integrated with the rear calipers. You can do the swap but you will lose the e-brake.

Our OEM front brembo 4 pot calipers are plenty capable already.

If you are looking for an OEM upgrade, I believe the M Performance 374mm (and larger caliper) system should bolt up as the normal B58 M-lite bmw's (M340i, M240i, etc) get the same 348mm front brakes as the supra, with the M Performance track trim getting the 374mm brakes

Our calipers/rotors are the same as the blue M calipers in this photo. The red caliper is the upgrade + the larger 374mm rotor shown in the second photo

This is very interesting

Happen to know if other components (master cylinder, etc.) need upgraded as well to compensate for the larger brakes?

I've got a set of 826m wheels in black with tires in my garage. Maybe I should put them on the Supra just to test fit.

 

[A91rookie]

my car was at the shop and while waiting for my wheels to get back from powder coating they slap these on.

I wouldn’t want 20s, but the fitment looks good!
