e30 with e46 lower arms

Post Mon Mar 17, 2014 3:21 pm

Just fitted e46 arms to and e30 with e36 hubs and my wheel is not centered in wheel arch.
I fitted the eccentric bushes to lollipops for offset yet it is still more backwards.
Did I missed anything.
Im using e30 topmounts.

Any ideas?

I thought e46 arms were only used by drifters who want a wide track, lots of lock, and don't really give a stuff about how it looks?

I've never heard of anyone doing it on a normal road e30

E36 m3 3.2 arms and hubs with e36 3.0 / e30 m3 offset bushes is the usual combination.

Well.. you may be surprised but drifters do care.

This car is for drifting aswell.. but track and road use also.
I know it can be done..just not sure why its not centered.

I don't know if this helps at all but... we have e36 m3 top mounts on our drift e36 to add some castor... you may be able to use something similar to dial it out? a picture of what set up you have will help

I think we need pictures to see exactly what you mean - but I would've thought without further modifications, the wheel would sit too far forward on E46 arms, rather than too far back! Do you have excessive toe out?

Naturally, E46 wishbones arn't designed to work on E30's so the geometry will be completely different and you'll need an assortment of different parts/mods to make it work. However, this chap has done it - and I believe he is a zoner too:

It is of mild interest to me given that E46 arms are aluminium and hence significantly lighter than the steel E36 M3 arms I have at the moment. But the increase in track is huge and some bodywork mods would be required to accommodate without running insane camber (less of an issue on a drift car though). Too much work and expense to save a couple of kgs per wishbone for me!
