What are the biggest discs I can fit in 15" rally wheels?? how about 16" rallys??

anyone try aftermarket front disc kits? Baer? Global West? Stainless Brakes? MP? anyone. I want to upgrade to the biggest, I am buying wheels soon and this with influence what size wheel I get.

I just installed a Disc Brake conversion kit from Stainless Steel Brakes it fit perfectly
and had plenty of clearance for my 15" wheels, and I might add it is a top notch kit well worth the money. Oh by the way I installed this on a 67 chevelle

My 68 Elky has 13" Baer rotors on the front with 17x8 wheels. You can run 12" rotors with 15" wheels.

That is what I wanted to hear. Do you know of any specific kits? I want 12" rotors under my 15" rallys. I would just hate to buy it and have it not fit.

I was thinking about a 12" rotor 2 piston caliper setup.

On the same subject, does anyone know if a stock disc brake setup (front) will fit under 14" "SS Magnum" wheels on my '72 El Camino?
