I'm running an over the counter from the dealer Dana 44 with a clutch type limited slip in a dedicated autocross car that I bought used a couple years ago and ever since I put it in my slow speed turning radius is about twice what it used to be. It feels as if the rear end is just solidly locked together and the front tires are just chattering straight. I'm just wondering if maybe the rearend is just too aggressive and won't allow the tires to differentiate? And if anyone knows how to relieve that if possible. Maybe change some shims or something to loosen it up a little?

 

Could put more LS additive in it...but I'm not sure about the lubricating effect it would have on the differential as a whole. ..?
