I've done some research but it seems most people have larger wheels with a bbk. will 14 inch rotors fit in the 18 inch stock coupe wheels. I am looking at getting the g37 brakes, or possible another bbk of 355mm.

 

you need to search up on the topic of disks for the wheels, this is what will bring u bbk clearance

 

14" rotors require a minimum of 18" wheels. But the offsets & disc type might also determine whether they fit or not due to caliper clearance.

 

alright thanks. yea i found the g37 akebono kit does not fit, but i wonder about the stoptech or the alliance that some 350z members have. i guess i'll be doin some more research.

 

most of those in a 355 does not fit. the 335 does fit though. i just installed one on one of my customers car

I use to run a Stoptech 4-pot front and 2-pot rear with 335mm rotors on a set of 05 sedan 18's

 

Clearance will depend upon wheel design, pad size, rotor size, and caliper dimensions. Here is a pic of a StopTech 4-pot/4-pot 355mm set up with an 18" set of Enkei NT03+M wheels. I've even seen a pic of a set of 380mm Brembos on a set of 18" Volk TE37s.
