I dunno what to do

i've been offered them they came of a touring car proffesionally made to fit esc cos - they sound the bollocks they are like super t's but center fixing. light as fook too.

just dunno if i like the idea of 1 nut holding each wheel on. and them being magnisium summit about x-raying them

what should i do?? i'm looking for 18's and i've got and esc and had a few in mind but these are quite special?

cheers

Daniel
