My limited slip differential is not so limited anymore. Shortly after I started tracking with slicks, I noticed that my inside rear tire would spin on corner exit. Over the past two years, this has gotten worse and the carbon fiber clutch disks in the diff are probably just carbon now. On straight acceleration, the diff feels fairly locked with both wheels pulling. I am currently running stock suspension with SFC. Shall I just rebuild the OEM diff or should I look into an aftermarket diff? What is everyone running?
