I've got an A4 1.6 SE, its an ok for driving about in - it'll never win any races, but it gets us there eventually. Its currently on the standard 16" alloys, I'm thinking of upgrading them with something bigger. I had 18" RS6 replicas on which weighed considerably more than the originals and this was a stretch too far for the little engine. At the same time the car developed an ignition problem which further zapped the power away. Before this was diagnosed I took the wheels of and sold them, its fixed now and its running fine. So, basically I'm looking for some advice. I think I'd rather go for OEM wheels as I'd of thought they'd be lighter - is this the case? would I be better to go for 17's or should 18's be ok? Thanks!
