Problems with running coilovers in the rear of a e36 m3

[Mantic]

I've read a few things about the RSMs arn't strong enough and will tear. Can someone please give me the true story and what can be done to fix it?

Shock towers are not designed to bear the loads.

Ok, well i'm buying a car with KW Coilover Variant 2 installed. Can anyone tell me if it uses a true coilover in the rear or a seperate spring and shock setup?

[badmonkey]

It's an inboard spring (stock location) and seperate shock. Front is coilover, rear stock layout.

Great. Thanks alot, i was getting a little worried. From what i've read these are suposed to be fairly good coilovers.

None of the coilovers on the market are a true coilover in the rear. The shock towers are a thin piece of sheet metal, not designed to support the load of the car.

Now, on race cars, it's a very different story. You can go much lower in the rear without coilbind worries with a true coilover and atually gain suspension travel. We have reinforced the shock towers and tied them into the roll cage, and then use a custom AD shock in the rear from Ground Control.
