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 (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.------
