Me too...16's are shaper, more precise...But not better...I've done Hundreds of laps at knockhill and if i'm bein honest i still prefer the 17's. Providing you have a decent profile width on the 16's...It's a different story all together.
Flick the steering at all on 16's and u're buggered, Make a small error on 17's you'll get away with it. But u are rite in sayin 16's for praticality and 17's for looks. I know which i prefer now.
I enjoy rimming mate, so i Stick to boys who have speedlines, Rota, Or OZ on their cars.
