I have decided to get Koni SA with H&R Race Springs for my E46 330Ci. Do I need camber plates? This car will mostly be used as my DD and maybe 5-6 autocrosses every year. Tire rack sells Eibach Alignment Kit (http://www.tirerack.com/suspension/suspension.jsp?&make=Eibach&model=Recommended+Align.+Kit&group=Recommended+Align.+Kit&autoMake=BMW&autoModel=330Ci+Sport+Package&autoYear=2001&autoModClar=&partNum=5.72080K&perfCode=S), will this work or I don't even need either this or camber plates since I'll only be autocrossing it for just 5-6 times a year?
Also, I have decided to get Koni SA and H&R Race Springs but to be honest I've never ridden in a car with this combination so I am wondering if any of you guys have any experience with this combination and how much stiffer it is compared to stock sport package suspension? Thanks all.
