Congrats on running the best!!! There is a thread on the Z28 section on how to convert your LE or SS to close to a Z28. Its a pretty good thread with some skeptics that think you cant get close to the DSSV setup...
I have made 3 trips down to see Pete personally for my suspension work. This car is on rails and feels like a miata but with a shit ton more power. Im running the forgeline/Pedders 4 x 19x10.5 DE3ps and currently the Michelin Pilot Super Sports in 305/30 R19. Considering R compounds for when i finally get out on the track but am concerned about keeping my LSX bottom end fed with oil. Not dry sump buy may go with an Accusump.
Also added CTS-V calipers with Cobalt Friction XR1/XR3 pads (track only).
Did you consider the Pedders adjustable camber plates. I go from -0.8 to -2.8 in a few minutes and back.
Great work, here are links to a couple good threads.
