Problem with both KOS and Stevetiggers suggestions is that we here in South Africa never had any of the models (E30 M3 E36 Compact) mentioned. Damn I can do nasty things to BMW SA' s managment for not bringing the E30 M3 to our shores :x

So there are a few other suggestions. Here goes.

1. 325Box, you need to source a 325IS suspension.
2. Redrill the hubs
3. Adaptor plates

I am also interested in this mod

Could you not use a Z3 rather than an E36 compact??

Cam you literally just offer up the z3/4 or compact suspension and it will mount ok on the steering rack, wishbones and the arb links up front. And what about the rear. Is there a combination of bits you need?

Surely Z4 suspension would offer a considerable handling improvement also...after all it is supposed to be a massive improvement on the Z3!?

yes but it would cost a fortune. Not everyone has Ԛ£Ã”šÃ‚£Ãƒ”šÃ‚£s to lavish on their cars
surely e36 compact or z3 would be a more viable option pricewise

Z3 M on the left, standard E30 on the right
Much larger hub, but almost identical apart from the gusset
Dont know if the standard Z3 is the same though

i wonder if this would correct + camber from lowering because in the photo it looks like the hub is at a different angle :idea:

To much caster if you're going to swap to E36 suspension at the front.

Even then there is way to much castor. Bushings or even a fully adjustable uniball at the rear of the controlarm won't do the trick.

It does fit, no problem there. You can just drive the car, no problem either. You just will lose front end grip because of the castor. If it's a street machine then you might not even notice it. The E30 already understeers from the factory and now you make it understeer even more. There are people who are racing with this kind of set-up, but it doesn't mean it drives really well. It can be corrected with massive neg camber, but that's only usefull for racingcars.

It does, trust me! When taken on a track and driven smoothly and precisely for fast laps, it tends towards understeer. Oversteer arrives with heavy-footedness and raggy steering (And naturally unpredicable road surfaces when not on the track!). A slight tendancy towards understeer when driven properly is the sign of a very well set up car you know!

The E30 and E36 control arms are the same. The problem is not the control arm, but the design of the E36 hub.

So apart from E30 M3, what would be the ideal cost effective alternative
