How much do you wanna spend inc tyres.
Id look for a set of 14x7 on a 205 45 tyre, there the right size for a mk1 imo.
Try
www.dubmeister.co.uk mine are on there rsl cults look awsome and still quite rare.
Also like Borbet T, revolution modern, and the steffan cups.
Dont think any of em are particularly cheap though, failing that clio 16v phase 1 wheels suit the mk1.
Well thats what i think anyway, Dan.
