The future of stock class?
Some valid points to consider.
1) If you use "Rebuildable Stocks" as the handout, you still have the same thing going on in the pits.
2) Mabuchi hand outs would lessen "Tweaking" in the pits, but lack of rebulidability (sic) would make for a very short competitive lifetime.
Really to make it a "Drivers" race, you need to have handout Cars like the IROC in Nascar. No tampering allowed.
