hey
ino there has been much discussion on this topic area but i have found my own solution
i was running 17s in 205/40 on a 1.2 16v mk3
the best thing about them is the looks but after bending them i was forced to go back to the standard 14s. The car was A LOT faster ont he standard wheels, but the handling was crap and it would slide and squeek round ever corner even when not going that fast
Now i have bought some 172 wheels. I reakon this are wikid cos they are the best of both worlds for me. I still have the same pick up and top speed as the smaller wheels, and nearly as nice looks as te 17s, and it is absolutly STUCK to the road
so
14s-look not so good, handle crap, very quick
17s-look wikid, handle ok, speed lost
16s-look good, handle amazing, quick, car just feels right
have u found the same?
