Performance and Tire Life

Most sports cars have negative wheel camber alignment as a factory setting to improve cornering performance.  Most of the sports cars are rear wheel drive cars.  On these cars, rear wheels are cambered in significantly to help cornering grip.  This comes at a cost of linear acceleration grip, since the tire contact patch is less than ideal with such wheel camber set ups.  Also most of the driving of a sports car is made on straight roads and almost every sport car ends up wearing its tires unevenly due to this negative camber set up.  This uneven wear causes the tire to wear down to minimum thread depth faster on its inner side, thus shortening tire life significantly.

This is not as significant on the front wheels of the sports car due to its lower negative cambered factory set up.  The front wheels benefit from camber recovery with steering input due to caster, thus don’t lose as much camber during cornering.  Also, front wheels need better grip for linear acceleration than rear wheels for braking performance and can’t compromise the tire patch needed for linear acceleration performance by having high negative camber set ups like the rear wheels.

Sacli suspension systems have superior camber control compared to these conventional suspension systems.  The Sacli suspension can have a very small negative camber set up, with minimal camber change through jounce thus providing close to ideal contact patch for linear acceleration.  This would both increase linear grip performance and tire life since the tire would no longer be wearing unevenly.  Sacli suspension can achieve this linear performance while it keeps almost ideal wheel camber during cornering for improved cornering performance.

Sacli system would be most beneficial to the rear suspension of a sports car.  The conventional suspension designs on existing cars suffer in tire performance and life due to the compromise they have to make between linear and lateral grip. Sacli suspension has to compromise much less than the conventional designs and as a result; it’ll improve linear and lateral grip performance and reduce maintenance cost with longer tire life.
