The Grp S Eligibility officer advised that they will be on the lookout for aluminium radiators and grooved brake rotors. Neither are legal and have been appearing in cars lately.
Radiators are free in size as long as they do not require modifcations to the body to fit and are in the original material (steel).
Brake rotors must be as original and cannot be "slotted", "grooved" or "drilled".

Are you sure about steel radiators. I always thought they were brass or something like that.
Yes - not aluminium
I guess the question is now, will the standard radiators cope ??? ??? I am guessing not, so is there another larger radiator that we can fit in (from a '90 or a '75 or something) or will we need to get another morgatge and have one made up as a special...
I am looking into it right now.
