chassis flex
O.k. guys let me start off by saying that i've been racing for maybe four or five years and i'm no A main driver but ,chassis flex can help in certain conditions .I remember the winternats in 2007 where the track conditions were horrible ,Mark Green who does r&d for Serpent , i noticed he had cut the chassis right down the middle starting from the engine mount all the way to the rear of the chassis. i asked him why did he do that and he replied he did it to get more flex and in return he would get more traction.
