I assume the price jumps once one wants to add camber plates and custom springs (a la swift)? How do these compare to the JRZ RS1 in a comparable setup?
You get everything listed in post#1 and in the photos.
The kit was designed around the OE upper mounts with camber plates as an option.
I believe most people here drive their M3's on the streets more than the track. If a track set-up is needed, Ohlins has the solution as well.
From our experience with the Road&Track product on 135/335's, the M3 version should be right there in performance with the RS1's given the same spring rates and set-up. In addition, we have done countless number of Ohlins installs, both with Ohlins and upgraded Swift springs, and with or without camber plates. We know what works on these cars. Below are some kits we have done with Swift springs and camber plates.
