Ive been club racing of several years now, and have been to embrassed to ask this question and unless im blind I cant find it anywhere in the GCR. But is it illegal to weld plates on the bottom side of the car where the forward cage is welded to the floor? Like most guys I jack my car up from side to side but it is playing hell on the mounting plates. When I first started out crewing for people with IT cars no one had them but I always assumed no one had them!
