M system turbine question

[Jsturgis19]

Im running ti rear trailing arms with e36 front hubs with hub adapters with the m system turbines in 17x8 anyone else running wheels similar if so what size tires are you running?

[E30-323ti]

I run the 17x9 (et22) on the rear of my E30, with either 245/40's DOT R's or 240/625's slicks

But I have a E28 5er rearend which is closer in track width to the E30 M3.
Can't use them on the front as they don't have enough clearance for the BBK.

What? I didn't think the E28 Rear Suspension, mounts to the E30 Body? Different mounting points.

They are only very slightly different, same style though so easy enough to adapt.

The harder part is converting to use the rear coil-overs of the E28, means new shock towers are req'd, and the old upper spring perches need to be removed from the body.

But worth the effort if you need a strong rear-end, and the late E28's have better trailing arm geometry (12° vs 15° sweep angle) and toe control links.

I had a very similar setup a few years back. Here's my '88 330is on E36/Z3 5 lug susp. 17x8 M-Systems with 205/40 tires. Unfortunately, the 6 cyl Z3 rear end is not very forgiving to low offset wheels, so it rubbed everywhere. Didn't end up running that setup for all that long.

I ran 17x9 et22 with 245/40 on e30 m3 rear setup.. Rubbed the inside of the quarter panel pretty hard under compression. Only way you'll fit them on a late model with e36/7 stuff is small tires, even with 17x8's
