Subject: RE: <E30> Suspension parts questions
The front sway bar mounting points are different.
The right way would be to weld some M3 mounts on your strut housing
and use M3 links. or you could bolt the bar to your links(located on
the A arm) but, these links will not be vertical anymore but sit at
an angle (This is how i have installed an M3 sway bar in my 86 325es)
Probably places more stress on the links but I have not had any
failures after 6 drivers schools and many autocrosses.
Can't help you with the rear bar as I chose to stay with the stock
Re: M3 springs.
Keep in mind that the M3 engine is significantly lighter than yours
so the car will sit lower than an M3 in the front. Should be OK
on the rear.
I had thought of doing this but, decided to get springs that were
made for the 6 cyl. I chose Hartge but, there are many others available in
the $200-250 range.
There are some digester who have used M3 springs, hopefully one of
them will share their experience.
