Need help keeping up with C6 Z06 & Porsche GT3 on Road Course

Regarding the Dana, most serious racers would give their left nut to save 40# of unsprung weight. You're not gonna blow up an 8 3/4 road racing. It also takes more torque to turn a Dana. Not tryin' to argue, just sayin'.

The TTI headers fit nice and snug to the bottom of the car with a little tweaking. The collectors come out perfectly through the t-bar crossmember factory " cutouts". Clearance to the left t-bar is very tight. I doubt a 1.24" bar would fit on my car without some serious header dimpling.

The trans may cause some issues. I got mine from Keisler and had to shim up the trans mount quite a bit because it made the back of the engine and therefore the headers, hang too low. It also screws up the front u-joint angle and engine clearance to the firewall. I have the trans as high as it can go without modifying the crossmember.
