E30 Zone

when my wheels spin up they seem to jump.... i noticed when i put my rear end back together i didnt have any anti role bar.

would the lack of anti role bar cause this? if so what models came with rear anti role bars?

what year is ur car and model what condition is the rear shocks

1989 it was a 3.16i but now has an m30 engine. but i'm using rear tailing arms off a 325i sport but there was no anti role bar with it. rear shocks are brand new bistiens....

It's called axle tramp get used to it. But you should check the rear beam bushes as they will make it worse if worn. ARB wouldn't affect this but you should really fit one.
