Found these on Ebay, I know that P-Slot centre caps are genuinely rare but they seem to be worth more than the wheels - http://cgi.ebay.co.uk/PIRELLI-P-SLO...s_tyres_Trims_Car_Rims_ET?hash=item3ca956c302
is quite pricey, especially if they're just plastic. i think p slots look better without the centres, so i chucked my old ones out. wish i'd kept them now..
they don't ever have Pirelli on them like some of them do i would rather have none that pay 50+10 P&P for chavley plastic ones
I bought a set of P-slots without caps. Machined the big central boss away, using a woodworking router, and painted them black. White car - Black wheels. I made a wooden template to support the router on the rim. It took about 1 hour per wheel. I tried posting a photo, but the minute the URL box popped up, I was lost. Lowered the unsprung weight a bit!
