Has anyone had any experience putting the e30 M3 aluminum front control arms on a Z3 or 318ti. What I am really interested in is how much weight they save over the stock control arms and if there are any problems with installing them.

Thanks in advance,

Paul

As far as I can tell...

...they are different enough that they just won't fit; I haven't heard of anybody even trying it. I would think that if it's possible, someone would have done it by now?:dunno: As far as weight, I've heard it's about 5 lbs of semi-sprung weight per side, which comes out to about $40/lb, which is ok, I guess, as weight reduction goes...

I think the biggest problem is that the front end of the Z3/318ti is actually an E36. it's the rear end that's E30.

Ah yes, thanx for the link, I learned something new today. :thumbup: I dunno man, I just had mine up on a lift earlier today and was looking at the arms, and they looked a bit different than my E30's arms. But if Turner sez they'll fit, who am I to argue?...:dunno: ...

I was going off Turner's web page that says the Al control arms fit the e36. Most of all I was wondering what the weight savings were and if anyone had installed them.

I don't think anyone has actually tried them on a Z3 chassis. They would likely fit, but not really sure until it is done.

I've got aluminum front control arms on my M Coupe. Got them from Turner, they are the same one's for the E36 M3. I couldn't tell you exactly how much lighter they are than the stock ones. I didn't think to weigh them before having them installed.

Was it worth the change or did you just step up to aluminum because you needed new bushings/control arms and it was a "why not?" type of thing?

It was more of a "why not" kind of thing, though I did need new ball joints. Reducing the unsprung weight was part of the desision as well.

I'd looked at doing this long ago... isn't there an issue with the swaybar endlinks? On the non-M's they attach to the control-arm whereas on the M's they attach up on the strut. Do the aluminum control-arms have the attach-point for the links?

Yes they do.
