1LE Rotor/LS1 Caliper?
I've done a number of searches without finding anything. I know the 1LE rotor is a little smaller diameter and thinner, but it's close enough to work. Machining the stock rotor friction area away probably works fine, but since you have to get different rotors anyway, I was curious if anyone has tried to do the LS1 calipers on the "bolt on" 1LE rotors? Opinions? Pitfalls? Just a quick street car with occasional trips to the drag strip to break parts.

Re: 1LE Rotor/LS1 Caliper?
You can't just bolt those calipers onto the 1LE stuff, there's more to it than that. In the past I have made a C4 HD kit with a C5 caliper and it worked great, the difference in thickness is only .15" so it's not much. The problem I see is trying to fit the larger LS1 carrier between the rotor and spindle. I don't think it'll fit.

Thank you Ed, that was exactly the information I was looking for. I expected that it would require custom adapter brackets and hoses minimum, but clearance for the caliper carrier is something I didn't think about.
Thanks again, you're the man!!

Glad to see I'm not the only person who thought of this.
Seems like a another option for people with skills.
