Dont know where the hell they went, but I managed to lose two of em, centre cap bolts for the little 3 pin key thing, not sure if the same key fits, but if anyone has a couple or spare ones that will fit the std 16 alloys on my 172, Id be eternally grateful. Ill have to take em all off now, give it the hardcore look it had at the ring at trhe weekend, LOL As Tom pointed out if they steal em, they may not stock em anymore and I can have turinis of 182 wheels, LOL
