The grind is for shaving down the .060 stump flush on the chassis U brace where the ball studs are mounted .
Recommend to do when you use the Chub ..
The part makes for less chassis roll and adds rear stability.
Not just for high traction, can be use on med or even less ....
The mod is very useful tuning tool , should try it and have in the pit box just in case .
