Min wheel size for brembos

[zx_volcane]

So im gonna need 40mm spacers overall? Not really viable for me :/
Is there any other brake upgrades other then gti to fit under 15's?

Depends what you want from your brakes, as said already gti-6 brakes are fair decent setup spesh if you go for some decent pads - plenty of stopping power.

I've got similar sized willwoods 285mm only bonus being that pads can be slightly cheaper as they're fitted to a bunch of stuff.

As welshpug says, plenty of options if you go for different wheels. steels tend to have minimal clearance for brakes.
