I have a 2006 300i ZSP... The car has a 3.64 LSD rear.
I am retaining the stock springs, I have a set of the bmw perf shocks waiting to go on. At the same time I will also be doing M3 front control arms.
The final part of the equation is the rear anti roll bar. I don'ty know whether I should go with the 14mm m sport bar, the e93 15mm bar or the M3 20 mm.
I do auto cross, and am looking to help the car rotate even better.
I don't want the car to be nervouse on the street... I want to be able to let somebody use my car if its raining and not worry about the tail coming around on him
Lay it on me folks
