Into my CSI. Anything else needed to "hand off" to my mechanic or is it plug and play? Assume I have to ditch the stock CSI diff cooler though right?
The one Im looking at is the M3 Evo (FD: 3.23, 25% LSD, big case) version, pops up on eBay quite a bit. Reasonable pricing. Anyone put one in a CSI before? At a nice 10% difference shouldnt impact MPG or drive-ability in a bad way but give it a bit more pep.
