trying to split rims on my BBS sport classics . so I can get them proper refurbed. decided to split rims myself as all local refurb places will only paint over . nearest place which will do proper job is in fucking Kent. so anyway. manages take out 25 bolts out of 80 total. further 20 heads snapped and 4 more rounded . then I stopped. 1 of the wheels have all the bolts out/snapped, but I simply cannot split those rims. tried bashing it out and soaking and so on... no fucking way. is there a trick to it? they must come apart?
