I have some black EXCEL wheels ordered due in any day. Parts guy tells me they have changed them and I might need spokes front and rear. I thought it used to be just rear and even they made wheels that used oem spokes alltogether. So.......anyone who has made the swap to EXCELs what excatly do I need? And what kind of spokes and nipples? I just love sayin' that word......nipples.
