hey i have a lupo 1.4 s, and the tyres are pretty bald so i was wondering if i could fit maybe 15" polo wheels not alloys just standard polo wheels. cause i think 13s are just to small for the lupo. dont want alloys cause they'll be wrecked in a week lol thanks also my car is really hard when changing gear gotta use quite a bit of force??? is this the clutch?
