The M3 trans is a larger unit, but if you use the TI trans & driveshaft, the //MZ3 diff will work with no issues. There are many //MTIs running the stock trans without any issues including myself. I haven't heard of one failing yet. Just make sure you use a //M3 clutch. Love to see you get the ASC working. I didn't have it on my 1995, and I removed it on my 1998 so I've never experienced it. 8.5" sticky tires does a good job of traction control anyways. __________________ SOLD!!! 1999 332ti //M Sport Titanium Silver M3 S52 3.2 I-6 Engine, M3 Clutch w/ ti Getrag Trans, Z3 3.15 LSD medium case diff and half shafts, OEM Hatch Spoiler, Eurosport HP Underdrive Pulleys, FDM, 17" DS1 rims, M3 Front Struts & Springs, M3 Instrument Cluster, 3-spoke //M steering wheel with tri-color stitching, SSK, CCFL Angels in Depo projectors with 5k HIDs |
