2018 xb2 diffs out on corner exit

[garryplant]

Really struggling with this Inner wheel is spinning like mad on corner exit .

Cars kit setting apart from 2 dot springs all round . Metal gears in diff

Cars is raced on Mb raceway carpet so high grip ! It goes well but after that bit more .

I have tried anti squat reduced and more tow in made it worse if you ask me .

Any ideas ?

Thanks
