I am rebuilding a diff for my dedicated track car, a gutted 325i with a M20. For years I have been running an 4.10. The last couple years i have been smoking the inside tire on uphill turns (which were i run has a lot of).
I just removed another 4.10 medium case from my 318 due to an engine swap. I decided I would rebuild this unit and when i pull the track car out of storage toss it in. This 4.10 seemed fairly strong. I pulled it apart (without stripping any of those allens) and it has what looks like a little wear on the clutches. Since i am in there i figure i will replace the wear parts. What is the consensus on running a 2 clutch vs 3? Its really a DE car so i am not looking for every 1/10th of a second. I am more concerned with tearing up my slicks on hills. Also is there any benefit to porsche vs bmw parts?
Thanks for any help. This is new territory....
