Hi mate, ive recently got a GP 1.2 active for my first car, and ive been reading up on the forum about putting 17" alloys on it ruins the gearbox due to the weight of them compared to the 15" steels you have. (i have the same ones) How are you finding the alloys you have atm?
Cheers
Was the car available with 17 inch alloys as an opt extra or did it only go to 16"? If Fiat offered 17's then it should be fine shouldn't it?
