I have more of these adapters if anyone is interested

The adapters are made by S2Gizzle. They’re just machined pieces of aluminum that bolt to the Supra hub and accept the M calipers.

I would give these a shot!

on the flip side, there has been more brake pad development for the 374x36 brake size. Before I was limited to just EBC blue pads which were completely toast after two track days... Like worn down to the backing plate toast.

While not advertised on their website, CSG offers their C1 pads and paragon offers R3, R5, and R7 supplied by Winmax in Japan. Additionally, they have two piece rotors for the front (374x36) and rear (370x24).

More options are nice but those are all still pretty weak offerings. I'm kind of amazed Hawk doesn't at least offer the DTC60 for that pad shape.

Hey guys, first post here. I wanted to add my 2 cents. I am currently running the 395mm x3m brakes on my m340i and 19” wheels. I did have to remove a little bit off materiwl off the calipers but they fit, very tight fit but been on for a few thousands kms now fine, also running endless brake pads which improved everything alot! Some photos:

Before: no track package so 348mm brakes..

Anyone know if I go with the 374mm or 395mm set up, would there be coding involved? Similar to what people do with retrofitting the 3 and 4 series using e-sys?

Would 395mm fit the oem wheels?

395 will not fit 19”

Did you read the thread?

 

[steven_rosario]

Did you read the thread?

yes, just confused on what the measurement are exactly for this specific caliper and the rotor measurement that i would need.

 

[Z4m40i]

I was gonna say something snarky like, “don’t be spoon fed, read the thread”….

But most of the info for m calipers is literally on the first page so…

don’t be spoon fed, read the thread, lazy ass.

The adapters and a 19" wheel that fits them, oem wheels do not. Well, they do, but wayyy too close for comfort for me:

Here is a spreadsheet I made with rotor part numbers, also has a link to the adapters. you want the 380 mm front / 370mm rear

I have adapters if you are interested. PM for details.

Question for anyone whos done this - Do i need M3 brake lines for the front or will Supra lines work?

 

[S2gizzle]

I have reused the supra brake lines. It has worked quite well.

 

[DarkZupra]

Well, apparently I screwed up. Picked up a used brake kit from a G80, got the adapters for the front.

The rear calipers do not fit. Do I need a different caliper mount? Different rotors?
