I hope this will help.Try step by step when changing setting..
1.Used the lowest rear roll center.
2.Rear inner camber link location,tried location 2 instead of 1.If still need more grip then try location 4.I always use location 2.
3.Reduce clucth Clearance to 0.5 or 0.6mm
4.Use Ackemann CB or BC
5.SRS wing shift to middle.
4.Used 60k or 50k diff oil.i've tried 30k,same issue like yours..the rear snap during on exit corner.U may also try to reduce from diff oil to 200k.
