As a point of reference, VAC Motorsports is putting a Quaife on mine, and my suspension is going to be modded as follows: M3 Rear Subframe Bushings, all the M3 Suspension Components Kit from GetBMWParts.com (front and rear arms, both sways), AC Schnitzer Springs, and JRZ RS1 dampers. I mention this because VAC is still suggesting Quaife is best for me. Granted I will only track a couple of times a year at HPDE.
