Lets hope the R classes are kept well defined
R1 - up to 1.6 near 'standard' 2WD
R2 - up to 1.6 with modifications 2WD
R3 - up to 2 litre petrol 2WD
R3T - 1.6 turbo petrol 2WD 29mm
R3D - 2 litre turbo diesel 2WD 32mm
R4 - 2 litre turbo petrol 4WD 33mm at the moment
Super Production to be seperate to R classes?
