Ron loves to fine tune the rear sway bar for mid corner grip & balance. If youhavent thought it out yetsway bars are progressive on corner entryfrom zero rate whenthe car is straightand progressive in rate as the car starts turns inreaching max rate near mid-corner when the steering gets to 100%. Sway bars are also digressive on corner exit from max rate back to zero rate as the steering unwinds gradually. The sway bars are one of the few tuning itemsthat affect the mid-corner roll through zone. Need the car to turn better here? Increase therear sway bar rate. Need more grip in the rollthrough zone?Decrease the rear sway bar rate. Ron designed our rear sway bar with 4 holes,.75 apart instead of 3 holes 1 apart for more fine tuning.
