What is the diameter of the rims you're currently running? If they're 18" or more, they'll very likely clear most big brake packages.

Also note that you could shim the rim if nececessary - hub-centric shims come in various thicknesses and are a viable solution. For example, I had my oem rear rims widened from 9.5" to 11.5" and I ran one-inch thick shims, bolted to the hub. Each shim came with its own studs, which the wheel bolted on to (the holes in the shim for the oem studs were in between the shim's studs).

Currently I have 18x9 front and 18x10 rear. my supra is a J-spec TT , which comes with the normaly aspirated brake set up. Theres barely any room between the brake calipers and front rims.

Im thinking of installing the north american style TT Supra brakes, not sure if its a good idea or should I just buy brembos or Stop techs?

one thing i havent seen being considered in this thread, is inertial weight.

remember, his application is road racing. so just weight and width alone are not the only factors.

a wheel that has more hub-centric weight, could weigh more than another wheel, yet still get up to speed (so to speak) faster.

vice versa, a wheel that has most of its weight toward the drop center and rim lip, will take more effort to get rolling, but be easier to control and keep momentum up in an application like road racing, where he will almost be constantly moving.

and depending on restrictions for his races, he may not need an intensely wide wheel if he gets the proper tires. applying the power to the ground is imperative on tire selection. you can have 335mm tires, and still not grip or handle for beans. while you can have a 275-295 width tire that would give you superior handling.

just some thoughts. everything else thats been brought up was farely spot on.

in my research, fikse wheels has a great selection of light, wider and weight balance. there are others, but like i said, my research lead me to fikse.

GL!
