請有Team C TS4師兄幫忙

我估计是你套平地车呔太咬地之故。

你可試用电線膠紙在车呔外側貼一圈，看看轉彎外翻的问题是否解决。

I am running TS4 (Asia version, no big bore shocks) with HW SCT-PRO and SC411, HobbyPro SC tires,  with more or less factory default settings. My TS4 won't turn-over unless big angle turn while >80% throttle on gravel.
So I guess your issue should be with your high grip tires.
