Many Porsches are not that fast....... I beat most of them with a 30 year old Mustang. I killed them with my ZR1 in 2012. The new GT3's are fast........most other stuff is decent but not fast. My Corvette buddy use to beat Porsches with his done up C4
I've upgraded to polyurethane bushing and a set of Hotchikis swaybars put on a set of 6 piston calipers along with 14" slotted rotors. Running the stock Corvette magnesium rims 18" all around. 265/40/18 front, 295/35/18 rear. It also has 6pt roll bar for safety. The engine is pretty stock, just headers, LS6 intake and a Vortech supercharger. That's all I can remember for now. lol
Interesting, you start by saying the engine is fairly stock, then hit us later saying you have a supercharger.
The car looks great! I bet those shocks will help a lot.
