I believe you gotta have rotors re drilled into 5x100 bolt pattern...

not sure on the bbk but that does defintily look like a baer caliper. whatever rotor thats on there like phewes said was drilled to fit your car. baer makes rotors for our car but i think they are built per order so it may take a bit to get some.

Doesn't look like a Baer caliper. The Baer ones have their logo on them. I'm with BBZ in thinking it's likely the one RSM used to sell.

For the rotor, you might want to take it off and take some measurements to see what you need. Then contact either Baer or SSBC to see if theirs match up. As mentioned, they'll need to be redrilled to 5x100 and machined to accept a hub adapter ring.

Measure the diameter, the offset from the hub, and the hub bore.

RSM machined some material from inside the rotor hat (as well as the re-drilling) but can't tell you how much without having a regular C4 rotor to compare against. I don't use any hub adapter rings with mine, and I have no problems.

Not Baer, but it is a C4 caliper, that is for sure.

Looks like RSM to me... 12" kit.

Measure the rotor.

The issue is that the rotors have been re-drilled for 5x100 and bill says it seems they've been machined on the inside too for the wheel bearing.

It's not as simple as just buying new ones.

Dump that RSM kit for a wilwood kit man. Well worth the work and $$ spent.

Those Baer rotors won't work, too thick. When I sourced out calipers, I used a 94 Y-body, non-ZR1 for reference.

shawn if you do decide to sell the RSM kit I want it. I want to be able to run my 16s Z wheels and have been trying desperately to find this kit. Unfortunately RSM/Zspec doesn't even make it anymore.
