Wilwood themselves make only one big brake kit, it needs at least a 16" wheel to fit.
Fastbrakes sells a kit that uses a Wilwood caliper and is designed to clear a 15" wheel.
Either way, it's total overkill if you're not going to be doing any track driving. The stock brakes are perfectly able to lock the wheels with all but the stickiest R-compound tires, so there's no real reason to get a big kit.
