I am new to dirt racing and just bought a used sprint car. The chassis is an 04' but comes with paperwork and is straight off the table/checked. Most of the bolt ons are pretty new, maybe 8-10 races old. If the car is dead straight, and the bolt on pieces are in new/good shape, does the year or the chassis really matter? I've gotten a few conflicting opinions, I just thought I'd ask here and see the consensus.
