Got some old school BBS wheel centres for my boys birthday in 15" like to build them up to ET20 (minimal back space) all round fronts at 9j and rears to 13j stumbled on few problems and brain freeze working out what size inner+outers needed and finding somewhere who sells them.

Thanks, Trevor

 

you need to start with what centre you have and its ET.

if they are BBS RS, they are 3 piece. inner, middle and lip. the middle is always 0.5"

there are heaps of places in germany that sell these parts (as well as the UK and USA but are a lot more expensive).. ill find you my contact

 

also goto www.wheel-whores.com and there's lot of stuff to help you out

 

try these for inners and outers

Sweet so for fronts i need 4" inner and 4.5" outer with 0.5" centres? And rears 4" inner and 8.5" outer rears does that sound right?

 

all depends on what offset your centres are - have a look and tell us

 

It is ET20 stamped into back of the BBS centres, had read of the wheelwhores site but that left me more confused than ever!

 

ah.. also need to know what model centres they are.. eg BBS RS167
