the conversion is easy enough to do withough any hassle. Only thing is waiting for the right hubs at the right
price.
i managed to pick up a set of hubs, sr20det calipers and discs, s13 rear discs with s15 rear calipers for $150!!!
Check the nissansilvia forums. there are always guys doing s14/s15 5 stud conversions selling their s13 gear!
