I would have loved to have a version of this cover for my small case diff when I was running it. I was always worried that it was cooking the fluid during track days but when I drained it after 4 track weekends the fluid still looked like new just with a healthy does of clutch dust added. I might try and find one for my med case diff but with the extra fluid capacity already I don't think it's too necessary with M44 power level. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
