First of the philosophy of anything being equal in racing is flawed. There will never be equality in crates or open engines. Hell, the crate engines aren't even equal to one another coming out of the shop after being built.
The minute you tell me I can't find ways of going faster that are within the rules is the same minute I sell everything. Racing itself is boring to me. Doing the research and engineering to develop a better, faster, LEGAL car is the fun part
As for the division Accord wants to start, it's an open sportsman class with no outer body work. Ok, so a savings of maybe $800 on tin. Other than that all the same expenses apply.
