they're on 17'' oz superleggeras, they were the lightest wheel i could find when the pulsar was running, but one is a tad bent so i have to get 1 more, i've been having a chat with my dad about doing it (he's also a mechanic with 30 odd years experience , also built many a car from saloon stocks to drag competition alterds) he thinks it is do-able and a good idea, i'm gonna try and rope him in to helping me do it aswell, all i have to do now is find a donor silvia, but cash is a bit tight at the moment
