hoping someone could shed some light on my query please, i have a set of td pro race 3 alloys and want to me what offset they are, the numbers on the rear of the wheel mean nothing to me ... could someone tell me what im looking for .... thanks

 

Standard Fiesta ST offset is ET52.5, I think Pro Race 3 are ET37 if you're looking at 17".

So you should have something that says ET37 somewhere on the back for a guess.
