I did the gen 2 caliper swap, never had an issue with using gen 1 rotors.


Just remember this is a documented safety issue. The Gen 1 V6 rotors start out 2mm thinner (22mm) than the Gen 2 RS/LS (24mm - minimum wear spec 22.4mm) so there is less material

This is just a concern if you put SR calipers on L.S./Sport/V6 Gen 1 rotors.
I have L.S. calipers and original new V6 Gen 1 rotors. AllData , et.al. show that's all ok.
-----Just make sure you match up SR calipers with SR rotors if you do this modification.------


I'd be sure super cautions about this. The Gen 2 rotors are the same diameter and thickness 24mm (new) RS/LS 27mm new SR and Gen 1 (V6) are 22mm (new). Best thing to do is verify the thickness of the replacement rotors and be sure they are matched to your caliper.

So if you are sticking any Gen 2 caliper on a Gen 1 rotor, you are putting them on a rotor that is under the minimum design wear limit for thickness.
