Troubleshooting 3. The 4 link stuff is at the top Swing arm suspension link angles More uphill angle of both left rear and right rear lower links creates more roll over steer. 4-link suspension link angles Excessive left rear upper link uphill angle creates under steer Increasing downhill angle of lower links reduces roll over steer and increases indexing Reducing uphill angle of right rear upper link reduces roll over steer and decreases indexing Increasing uphill angle of right rear upper link increases roll over steer and indexing. The adjustment range is 14 to 18 degrees. Stiffer rate makes car tend toward over steer Softer rate makes car tend toward under steer Left rear spring Stiffer rate makes car tend toward under steer Softer rate makes car tend toward over steer A higher tire pressure at the right rear will loosen the chassis A lower tire pressure at the right rear will tighten the chassis A higher tire pressure at the right front will tighten the chassis A lower tire pressure at the right front will loosen the chassis A lower tire pressure at the left rear will tighten the chassis Keep a constant check on tire pressures - Racing tires bleed down constantly - Check and adjust pressures just before the car heads onto the track Every time the car comes off the track, check tire pressure and stagger. Always write it down. Always use an accurate calibrated tire pressure gauge If you drop the gauge, get it recalibrated Alex George / Assistant Engineer / Team West-Tec "Rubbing is racing, get over it!"
