ok, so this is not about w2w. all about track days / hpde.
I am at a stumbling point, participating in Porsche Club HPDE,
Black/Red Advanced Racer Group, I am getting passed by 2016 Cayman Gt4's, and 911 Gt3's., and newer cup cars.
Very comfortable in the groups, 50% pass/ 50% I pass.....

I am at the point of sliding the car, just to keep up, albeit controlled.

Have I reached the limit of a 4th gen?

The car is a 1998 Trans Am, built by Wheel to Wheel for competition in the 1998 Motorola Cup Series,
then Grand Am gt, then AIX,Ite..........

Should I Accept as is, or is there something to do (cost effectively) to be quasi-competitive..
(Remember, it is only HPDE/track days, not competition)

Specs are: 1998 Pontiac Trans Am, ls6 (little cam, 392 RWHP, full cage,, 3650 w/ driver, nascar front bar, one off adjustable rear bar,
