    Finaly got the Torsen in my RS2 with new bearing and bushes so have a new diff
    The car feel great even could make it slide from the tail coming out of the round about.

    But i still think a 1.5 way limited slip would be better at entry of the curve.

                    Most people in germany say that the Castrol TAF-X is very good for the tranny and the Castrol SAF-XJ is very good for the Differential!

                        I use IGOL Rallye Gear 80W140 synthetic
                        As those torsen goes very hot and like Lee said need some strong oil film.

                            Tried to do v8 diff swap today but could not finish, when fitting on the cover and tightening all bolts we noticed that diff will not move freely, you have to use allot of force to turn it round.
                            When undoing 8 bolts just slightly the diff starts to move nicely.
                            We also tried to take away very small about 0.35mm spacer washer from under the crown but that after tightening all bolts left us with small play in the diff, in ideal world we would need to put 0.15 mm spacer washer in but where can we find one??
                            I think that doing diff swap on the car without removing it away from the car is big NO NO , cos you will never be able to check if new diff is turning freely and this will get diff to overheat and bearings to go south.
