Wheelbase only sell the wheels, they do not stock the centre Cap stickers.
*Series1turbo* on here made a bach of them and theycame out really well, im pretty sure he was only doing the one batch.
I search High n low to find who to get them off, even was in contact with Rondell in Germany, which i thought i had hit jackot, but when i recieved the ones in the post, they were tottally wrong. Then found another company that said they could supply them, (cant remember there name tho) and when i got them, they were also wrong.
You will be hard pushed to find some mate, the best thing you can do, is if yours are good confition, take them off, get rid of the old sticky stuff and replace with new sticky foam and re-attach the originals.
