I don't think excluding chassis makes any sense for STL for a couple reasons.

-The published philosphy is clear that any chassis/model run manufactured from 85+ is eligible for STL.

-Best way to prohibit class growth is have the overriding potential of what chassis' might be ineligible next year or forward.



I think the best and easiest thing to do would be to leave the chassis selection free, and limit the engine choices only. That way you only have spec lines for engines.

Other wise the class will be spec-line hell between engines and chassis.

The magic and attractiveness of this class is the open ruleset regarding chassis and engine combos. To restrict chassis IMHO, is a big mistake.

I say allow the S2K 2.0L engine with restrictions. Same with the ITRSX-R engine. The same way the BMW N55 3.0l single turbo engine in STU is allowed - with restrictions.

I really don't understand the reasoning behind restricting cars for some ambiguous reason in a class that is clearly designed as open to all cars. Restrict the engines not the chassis.
