375-380mm rotors/discs under 18" wheels

Bumping this old thread, does anyone know if a 380mm rotor can fit a 19'' stock ZCP wheel? Stoptech trophys

You'll need a spacer to clear the caliper but yes it will clear.

I run a 380mm on my te37 without any issues.. Check my journal for photos.

Good deal, thanks all

Apex EC7 R18 wheels accept even 390mm brake rotors with good enough clearance due to their flat inner. 380mm fits with a LOT of clearance into them.


390mm on pic






380mm





there are quite a lot R18 models with the flat inner these days, due to the modern cars with the large brakes, like BMW M models (f8x) for example, where minimal brake diameter 380mm, and a lot of people, who prefer to use R18 wheels.
BMW offer even oem R18 rims (forged if i'm correct), which fits on 380mm - 513M style.

Carbon ceramics? Nice!

Here’s my Brembo GT8 380mm on both 18” EC7 and ZCP’s. You’ll need spacers with the zcp to clear.

I think the killer track setup is going to be your 6 pot Brembos and brackets using OE E9X rotors that we can buy from FCPEuro. Looking forward to that group buy!!

i don't like to use e9x rotors on e46 platform. they have a lot more height (more "offset" to inside), 52.5mm on e46 compared to 62.2mm on e9x. so to fit them you need to cut or remove rear dust shields and even after that you will get too little gap between rotor surface and tie rod rubber boot (few mm only).
