b"TECH TIP PAGE Tech Tip 30: Fine tuning the balance of your race car is easy with the right strategy & components.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 when the 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. Plus you can split holes, providingthe RSRT rear sway bar with 7 rates! If the bar Ron specs for you has rates of 161#, 183#, 210# & 244#by splitting the links, you add 172#, 197# & 227#.This allows you to finetune the Roll Through Zone rear grip for near perfect neutral, balanced handling. Tech Tip 64: This may sound funny, but Ron Sutton does NOT KNOW what spring & sway bar rates a race car needs without running computer calculations & simulations based on each race car's specifications & geometry. There are too many variables & these variables matter. Common variables that matter:Wider track widths require less sway bar rate than narrower track widths A lower CG requires less spring & sway bar rate than cars with higher CGs A lighter race car requires less spring & sway bar rate than heavier cars Lower roll center cars require less sway bar rate than cars with higher roll centers Cars with higher front end dive travel under braking require softer springsCars with lower roll angles when cornering require higher sway bar ratesCars with higher anti-dive in the control arms require softer front springs All of specifications & geometry parameters that vary, affect the optimum setup.
