anything with an LS6 or an LS2 had them. This includes '02-'04 Z06's. '05-'07 C6's. Also the '05 and '06 GTO's had them. Finally, I believe the CTS-V from 04-06? had them also. I could be wrong on the CTS-V but I am sure on the Vette and GTO, I have owned both.

Also about the springs. Obviously the yellow ones are easy to spot but the non yellow stock LS6/LS2 springs are the same spring (good to .550 lift and the same pressure).
My LS6 CTSV has just regular looking springs (no markings) and I've recently tested different color springs off of various 243s all have the same spring pressures at 1.8" (installed height) and 1.25" (max lift).
