I fancy fitting a set of 17''s to my MK3. Just wondering if any mods are required to accommodate the slight increase in diameter. Cheers.
This depends on a great many factors such as existing ride height and suspension travel, wheel width, wheel offset, tyre size, tyre brand etc etc.
TBH 17's on a MK3 shouldn't be a major trauma providing you stick to a 17x7.0 with an offset of +35 to +42 with 205.40.17's. This
shouldn't rub on a std height MK3.
