I received my wheels today (18x8.5 ET45) and to my knowledge, they were meant to sit flush with the guards (as they do on the GTI we tried them on). Well, they don't. I'm pretty ****ty as this wasn't the look I was going for, but I've got them now so I'm going to try and work with the situation therefore I know absolutely nothing about having them on my car and what to expect/the limitations of having them.

They only protrude 10mm out from the front guards (haven't tried them on the rear yet) but what I'd like to know is how having stretched tires on the car would effect handling/grip. I'm not a boy racer and I'm in no way going to track my car. However; I do enjoy a spirited mountain run on the odd occasion.

Thanks in advance,
Alex.
