Wilwood brakes and factory wheels? 71-72

Just wondering if anyone is using the factory 15 inch SS wheel (71/72 style) with the Wilwood 12.19 rotors. And if so what caliper? Can the 6 piston Dynapro fit? Or the 4 piston Dynapro or Dynalite? And if you have them what spindle are you using or tall ball joints?
The plan is for all aftermarket suspension/coilovers and Wilwood brakes but I need to be able to bolt on a set of factory wheels at times. Just want to get the biggest ones I can get to fit the small wheels and not look puny with larger wheels.

Re: Wilwood brakes and factory wheels? 71-72

Wilwood has wheel clearance diagrams with each brake kit on their website. I used them to measure the Weld wheels on my 68. I discovered that only their smallest rotors would fit my application. You really need to take off a wheel and check their diagrams with a straightedge and a measuring tape to know for sure.

Re: Wilwood brakes and factory wheels? 71-72

I can almost guarantee the brakes you want will not fit the factory wheels.

I had to completely custom design my brakes to fit my 15x7 keystone klassic wheels. I run an 11.75x1.25 rotor with a Wilwood Superlite caliper. With a different bracket and slightly more offset, I could run a 12.19" rotor.

Unfortunately the 11" kits might be your only option from Wilwood, but the truth is those kits offer worse performance than the stock setup.

Well that kinda changes my plans. Might as well just put the 17's or 18's on it and use a larger brake kit.

Yup. I love the looks of 15 wheels on these cars, but it definitely limits choices when it comes to better braking. But.... unless youre road racing, I think the smaller disc brakes are well up to the task of occasional hard stops.

Agree. But if I put a set of 18's on it will 11 inch rotors look a little small? And yes I am concerned how it looks. Lol

Id THINK 17s and 11s would be perfect. But youd about have to have both the wheels and brake system measured out together unless you can find someone whos already put together a particular combination. In my case, my 15 Weld wheels wont fit over the smallest Baer brakes, even though other 14 wheels will. Theyre just tapered in too far.

Im prejudiced by my old-school upbringing, in that I think 17s are about as big as one can get away with on classic muscle cars without the wheels looking out of proportion. But others run 20s and are very happy with the look. Its just my own thing.... on the other hand, Ive always thought the absolute worst look is big open-spoke wheels with miniature brakes behind them. You wouldnt be there with 18s and 11s, but again, everyone has their own tastes and they may look great. I just think tires need to fill the wheel wells and brakes need to fill the wheels for the (my opinion) proper look.

Agree I still want a tall tire, probably 27 inch. So that points me towards the 18's. More choices. I have 26 inch front tires on my 68/69 Camaro's. They are small and I think they would look lost on a 71 Chevelle. Those cars have Strange 11.25 rotors with 4 piston calipers. 15 inch Welds, Billet Specialties and Cragars fit no problem. So now I'm leaning towards the 18 inch wheel and the 12 inch Wilwoods won't break the bank.
