Default Will oem C5 or C6 rotors work with the C5 Wilwood SL6 kit?

Does anyone know the offset of C5 & C6 front rotors? Visually they look close to the Wilwoods. The Wilwoods are 13.07" x 1.25".

I would like to try and substitute these in place of the blingy 2-pc drilled Wilwood rotors at $240 each. Search was coming up empty...

Wilwood has GT rotors without the drilled holes. 99% sure stock rotors will not work, only with special brackets like LG has for his kits.

I believe you have to use the Wilwood caliper and bracket that LG is selling. Not sure but I think the caliper is different as well as the bracket. It might be worth a call to LG and see if there is a difference as they might be able to sell you a set of brackets if the calipers are the same.

I read some on this, it seems they use wider calipers because they are actually cheaper, but then run a thicker pad. Obviously this would necessitate using a different bracket.

To me this doesn't seem to say anything about the rotor fitment on the Superlite kit.

The Wilwood and C5 rotors are the same thickness.

Do any of you guys actually have this kit or the LG kit? No offense, but to me, 99% sure means you don't know.

They don't use the thicker caliper just becasue it is cheaper, it is a much better way to go with the thicker pad and option of therm lock pistons. Just becasue a rotor is the same diameter and thickness does NOT mean it is anywhere close to fitting. I know guys who have the regular Wilwood kits always complain they HAVE to buy wilwood replacement rotors so I would say they are too different. If you need 100% why did you not just call Wilwood and ask?

I don't want thicker pads and I don't want wider calipers, I don't care how much better they are. I already have these calipers and pads and want to make use of them. Wilwood's GT rotors are also $200+ each, so I'm hoping that's not my best option.

I'm not going to assume anything, that's why I asked in the first place. And I know that rotor offset is relevant to fitment, which is why I asked in the first post. Please don't treat me like I'm stupid. I'm simply looking for an answer that you don't have.

I sent LG a pm, hopefully they or someone else who's tried will respond.

I checked dims on the Wilwood 2-pc replacement rotors that fit the C5 calipers, these have got to be the same offset as the oem C5 calipers.

C5 2-pc replacement rotor
12.81" x 1.25", hat offset = .25"

Superlite C5 kit rotor
13.06" x 1.25", hat offset = .41"


So It looks like it'd be a worthwhile investment to make a copy of my adapter bracket but .16" thicker. Sounds too excessive for shimming. I have plenty of room from the back of the spokes for the caliper to stick out a bit more.
