Any track guys have any before and after comments or data from installing the APR GTC-500 adjustable rear wing on a C6 or C6 Z06? Decreased lap times, stability, balance, quality, etc.? Did you use a front splitter as well?

I use the GTC 300 on my car and have no complaints now. We did have some issues at first but Johnny at APR took care of it in a timely manner. I have drove a C6 ZO6 with a GTC 500 and othe minor upgrades. I felt the stability was good at high speed braking (150+) and did not reduce lap time due to higher corner speeds. Over all APR gets my

So you're saying the car felt more stable under braking but didn't go any faster around the track? You think the drag offset any benefit of additional grip? Was it a high speed track or a shorter technical track? Do you know what the "angle of attack" setting in degrees was on the wing? Thanks for the info.

On my car (C5) it made almost two second difference for the better at Road America. The C6 I only drove with the wing so I could not compare the same car without it. I do not know what the angle was on the C6.

2 seconds for 4 miles is not much!

Don't they spend over a million $$ per second in development on the F1 cars??
