367/ alloy heads and intake/ TTI's and full 3"duals; A833/GVod All-alloy;
Rally Suspension/ PDB, PS, 1.03s; no rear seat
Kidney-Slot alloys; 14X7 and 15x10s BFGs
the rest is stock, scaled 3440 like this, No fiberglass,
3 inch exhaust is a good bit heavier than 2-1/2.
The GV/OD is a big added weight.
PDB can become manual disc for a good weight savings.
P/S you s very heavy.
1.03 T bars are a little bit of weight.
The 15X10 wheels and tires can go thinner. What is missing from you hooking up (besides control of the right foot) is a decent rear spring. I’d suggest a CalTrac set up with there mono spring and bars. There shocks are better on all 4 corners.
This is the obvious. Never mind going to a street strip mode or race weight reduction. My wife’s car has much of the above listed weight reduction items and scaled super close (just under) to the registered listed weight of 2990. (Near zero gasoline in the tank.) Her car is all steel. But lacks much of what you have that I listed.
Your gear vendors is a BIG offender. But I know that is not going anywhere.
