Whats the biggest brakes you can have with a 15" wheel?
As much talk there has been latly about 1LE, bare, c5 and so forth, I wanna know how big I can go and still run skinneys and slick's on the weekends.

 

I'm not sure about the fronts, but the biggest brakes I've seen for the rears that will work with 15" wheels are the ones that came with the B/W 9 bolt with PBR calipers. I'm still trying to find a caliper upgrade to dual piston (15" wheel safe) but I think thats the biggest rotor that can fit behind a 15" wheel. I'm stuck in the same situation you are. Need to be able to fit 15's when I race. Daily driver wheels are 17's but when I go drifting I need to be able to fit 15" wheels on the rear so I can switch them between runs. I have 6 15" wheels for drifting now. That leaves me 3 sets for the rear. Almost enough to last me through a day. I need a trailer!!

 

Do research- bigger is not always better. The brakes operate best at a certain temp. To big or to small = loss in performance.

 

that is up to the brake pad


but also if you get a larger rotor even though it might not heat up as much you also have more surface area as well as leverage and that might make up for the difference form th etemp

 

Ok back to the question Whats the biggest brakes you can have with a 15" wheel.

 

Are you talking drum or disc?

I know I have 13" drums on the back of my 1/2 ton Chevy PU.

As far as discs go..... it all depends on the size of the caliper. That's what sticks out, and needs clearance inside the wheel.

It's also gonna depend on the inside diameter of the wheel. Different wheels are made different ways. Not all 15" wheels have the same ID.

To answer your question is impossible without more info. Even then, not too many people here know the total area of every rotor/caliper combo.

 

Speakin of this topic, have u ever seen brakes on a V8 Lincoln LS w/ 18's? Holy crap, if you put a quarter in between the wheel and the caliper, it would scrape lol.
