what you moaning about carlo, its same for EVERYONE and same in ANY rece series, RULES are RULES and if you cant abide by them, find a rece series where it passes the rules.

2-2. No tube frame vehicles or tube frame chassis extensions are permissible unless part of the OEM structure as defined in points 1-1 to 1.5. Space frame chassis are not permitted, additional triangulation and bracing of suspension turret/mounting points is allowed and as long as the modifications do not break condition 2-7.

simple fact is if they allowed people to spaceframe their cars costs would be stupid to be competitive and they wouldnt even be remotley a road car.

what you gonna moan about next, not allowing slicks?
