Hi all, I have searched through the forums and cannot find anything related to this issue. I have just received my RSfour S, it is not complied yet but i have borrowed the trade plate from my mate that imported it to take it for a drive.... Now problem is the Rear diff feels like it is Locked, when i turn a tight corner / park the car etc it cherps / scrapes.. and carries on like a locked diff. I know that the rs4s has the GTR LSD, but it should not act liks this should it ??? Other than that the car is Great I love it, very quick and handles so so much better than my S1 Auto. A mate of mine sugessted to change the oil in the diff and drive it for a week and it should sort itself out, im not sure about that tho so i thought i would consault the knowledge on SAU. Can anyone shed some light on this issue for me ??? Oh the other thing that does not feel right to me is that the car is very stiff IE car is in neutral and handbreak off and it is very differcult to move.. i cannot even push it, Diff also ???
