TM4 centre diff Oil
 

Going to give the centre diff a go and was just wondering what oil weight people are using for different surfaces.
Thanks for any reply in advance.

100k is a good starting point, with say 250k for v.high grip and 40k for low grip.

Thanks I'll try 100K for a start. Do you find it better than the slipper or just different? Just thinking once it's in I would rarther leave it in.

It's different that's for sure, it feels like you lose a lot of punch but it doesn't show on the track. You end up with a very easy to drive car.
