Be wise... determine your sanctioned racing club, etc., determine which class you favor to run in, as well as how much money you're willing spend on the ;project and the typical race season (travel costs, entyr fee costs, tires, etc.

I've seen many racers modify their car without ever considering any given club's rules in different classes, then only to find poor race class results. Go to the extreme of the class rules so that you can stay within that class on a competitive level, rather than not having the car modified to the max and having poor weekend results.

You may not finish in 1-2-3, but you don't want top be dead last all the time.
