just ordered manual brake kit to replace the stock power brake set up so I can stop at that track. My buddies and I usually rent do a track rental at MIR once or twice a year, much better track and longer.

Grandville, the motor hp curve does not noseover till 6850 rpms, so I think more gear would help and since this is a street driven car, maybe Santa will bring a gear venders od next year

True you make power up higher which should be more mph, but if your 60's weak now from lack of traction, it will only get worse with more gear.You will have even more SLR to try n plant all that torque.it won't show its true potential.

I just got some 10" draglites for the rear to replace the 8" wheels on there now and will get some 275 x 60 or 50 m/t DR (whichever fits better). That should help it grab. Probably will do one thing at a time. My goal is 6.20-6.40 1/8 mi et and high 9.s 1/4 mi. Hope I get it. Your car runs pretty hard so I'll consider your advise.

Got Herb Adams Adjustable shocks in the rear(12 years old when I used to autocross the car) I did just install QA-1 coilover shocks in front with 450 rate springs.

The QA-1 replaced the factory springs also?
(your front end modified?)

I'd check for shocks topping out.
Usually the 'porpoising' is from a mis-match in springs front to rear.
(harmonics - like too stiff front)

Try some softer springs on front plus check for shock topping out.
(or limit the travel of front for a couple passes)

Also what's pinion angle?

Lots of things to try that don't really cost much to see what works.
