I have a few questions regarding brakes. What determines if a wheel can fit without using spacers? Is it the rotors, calipers or a combination of both? As you can see, there's a small spacer that's necessary for the stock ap2v1 wheels to fit up front. The gap left is about the size of a credit card or less. My ultimate goal is get aftermarket wheels, and I don't want my options to be limited to ones where I'll need a spacer to fit them.

The kit came with the car when I bought it and I don't know what model they are.I haven't taken the rear wheels out to really look at them, but the rear looks to be the same rotors, but without the dark purple part in the middle, and it's using oem calipers. No spacer is required for the rears. If I were to get a different set of rotors, can I still use those calipers on the front?

I think the front rotors are warped. When I jack up the car and spin the wheels, I can hear it rubbing on the pads a little. I can also feel the pedal vibrating just a little when applying the brakes, but not much. I don't know what I should do. Should I:
1. Get the front rotors turned? I called a shop and they'll do slotted and drilled rotors for $20 each.
2. Get new rotors all around? This goes back to the question I asked before about being able to use those front calipers or not. I plan on getting the Stoptech slotted rotors & pads kit that's for sale on the sponsor marketplace if I do.

Thanks!

It is mainly the caliper that is responsible for wheel clearance. The rotor hat is designed to center the rotor in the caliper. You only need to replace the rotor ring, not the whole rotor, measure the rotor and buy a replacement with those dimensions from Wilwood or a site like Summitracing.com. Oem size rotors and pads will not work with that. There was one Wilwood setup sold by Partshelper that may have utilized the oem rotor. I have no idea if this is that kit with a 2 piece rotor. The minimal spacer required to clear oem wheels makes me think that is not oem spec.

I've search and I can't find any Wilwood rotors that have that same pattern. I'll just bring them to get turn tomorrow. It's cheap to do and if it doesn't work out, I'll just get change out all 4 rotors. I don't want the front and back to not match lol.

If I'm successful able to use them again, seeing that the ap2v1 wheels require a small spacer to fit with those rotors, how much more difficult would it be for me to find aftermarket wheels that'll fit without using spacers?
