13mm ofset ok ?

[Paul in NZ]

Are these bbs wheels ok?Is the extra 12mm width countered by the 7mm offset...do they there sit inboard or outboard compared with 20mm offetwheels??
Do they require rings??

They'll work perfectly - same as my ACS wheels. You will notice that 235/45R17 tires flare a bit at the rim with the wider spec. The extra rim witdth seems to be all outward - inner edge stays about the same as 8" wheels on ET20.

Here they are on the old 535...

My old BBS-RKs 18 inchers were ET13, they fit and rides beautifully. I guess my fenders were already rolled in the rear for 245 width tires. It will rub if not rolled under loading.
