T/A Pocket Guide to High-Performance Handling
By BFGoodrich, Appropriated from
The Tire Rack Website
|
Overview: The keys to high performance handling are T/A R1's, a quality suspension system, proper chassis adjustments, and properly balanced tire pressures. Aim for the theoretical ideal Neutral Steer matched front and rear traction. Understeering is a plowing or pushing effect when cornering. Oversteer is the rear sliding outward on turns.
