damnit im talking out of my ass. In my opinion i would just get some drilled and slotted oem sized rotors and some bad ass pads. But it really depends on what your going to be using it for. I got a really really good deal on my rims and the brake kit thats why i did it. The power i lost from putting heavy 17's in compared to my racing 15" was rediculous. It was like taking away all the bolt-ons i had. Another reason i got them is i do a lot of canyon racing with my friends so it does help with the heat. If your looking at dragging and just want to stop quicker dont get the big brakes. if it is for Canyons / Road racing with lots of turns get the kit.
