Darren, John many thanks for your helpful posts, im going to measure the studs as the wires havent got any spacers between them so could be the short option. In regards to wheel size is 13 x 5J's the usual wheel. The offset of ET 20 and the same wheels would look great on my Mk1 Vitesse, does the offset bring the wheels further out towards the wheel arch hence ET20?
Im currently running 165/65/13 tyres would these fit on the 13 x 5J's?
Sorry for all the questions
Regards
Rich
