E30 Rear Suspension: (shared with E36 318ti and Z3s)
E30 Suspension
The E30 chassis has a decent suspension and the rear trailing arm
configuration was used in all E30 models as well as some newer cars
including the E36 318ti and the Z3s. These later models give us
options of fitting the E36 rear suspension from a 318ti to the
E30. I have heard of people trying to fit the Z3 rear end,
particularly the MZ3 or M Coupe would be of interest due to the
reinforcements, but I have yet to see a successful
implementation. Treehouse Racing sells all the parts as a bolt-on
kit. I have included a few pics of the E30 suspension
below. A nice upgrade if your steering rack is leaking to to put
in an E36 rack which has shorter lock-to-lock ratio. The E36 M3
rack is the shortest.
