I recently installed Vorshlag's "Street Pro" suspension on my 2011 GT and saw a 9 second improvement in lap times at Palmer up here in MA. Went from a 2:03.9 to a 1:54.6. I hoped the car would be better but I didn't expect this kind of difference. Only other before vs. after change was a Whiteline adjustable PHB to align the rear axle.
In fairness some of the improvement probably is me learning the track better. But the improvement in squat, dive, and roll was dramatic and the camber plates seemed to give a lot more front end grip.
Other mods on the car (both before and after) are 18x9.5 Apex EC7 wheels, 275/40/18 MPSS square setup, and the standard FRPP 14" Brembo brake upgrade kit.
Overall I'm thrilled. And thanks to the guys at Vorshlag for spending plenty of time with me on what was a very modest sale for them.
