They won't work. Non-M struts are one piece, where as E30 M3 struts have a 2 piece strut: 1 piece for the strut tube, 1 piece for the steering knuckle. That spacer goes between the two pieces.

Yes. As he said they won't work on 4lug e30's.

I need to pick up a set of those for my car though.

does it actually raise the car up 1" or does it just act like you raised it up 1"?
i know i cant get them but just wondrin

It doesn't raise the car at all.

It corrects control arm and tierod geometery for slammed cars.
e30's lowered to the point of mine have control arms and tierods pointing up. Thats sucky.

Very interesting - so it makes them more parallel to the ground...good work.

Too bad the picture is upside down, would have been easier to figure out wtf it was...

Roll center spacers.

Several years back we made a set of these for a Mazda RX3. $148 is ridiculous! You have the M3 piece to use as a drill template. Clamp the pieces together and center punch through the M3 piece. The center hole may only be for lightening. You have lowered the COG by lowering the car and are raising the roll center with the spacers-shortening the moment arm. Only the control arm was changed-not the tie rod angle. It tended to lift the inside wheel and quickly went to standing on the outside one. We were doubtful that it helped. After taking them out the car felt freer. Worth a try. Maybe different on an E30.

Looking at the M3 lower plate, the tie rod is attached and would also be lowered. There is also the grooved interface that would have to cut on a boring mill. The Rx3 piece was a lot simpler.
