I went over to help Vin on his last minute track prep stuff for his E46 M3 and although replacing his splitter brackets were not part of the to-do list, we found out that his current ones were damaged. Check out this video to see his OS Giken diff swap along with a cool montage of Driveshaft Pro installing the LSD into the OEM 210mm diff case. Oh also, you can see me using his Fikse Wheels as a workbench to drill into his carbon fiber splitter!
