Anybody running the RMS AlterKation? Was it really worth the cost?
I also wouldn't take the "3-series" as meaning anything. What 3-series? What options? My 330 is basically an engine shy of an M-3 (as I understand it), same suspension, same tires, same brakes. A 325, on the other hand is much less car, all the way around.
And, as for hate. I don't see anybody who prefers to stay with torsion bars spewing anything. If anything, it is the other way around. People who have spent large sums of money seem upset that others don't share their enthusiasm for the aftermarket suspensions. The OP was asking for opinions, we all gave them.
