More Grip, Better Tire Contact Patch

Updates the rear suspension camber curve to meet the needs of modern, wide, low-profile radial tires. The result is superior grip in turns, superior grip in straight-line braking, reduced tire wear. Excellent for both street and track.NEW & REDESIGNED TO BE A MUST HAVE PART FOR ALL CLASSIC RACE 911'S

  • • Improved contact patch in turns
  • • Improved contact patch for straight-line braking
  • • Go street-to-track with one camber setting
  • • Reduced tire wear
  • • Reduced camber thrust/rolling resistance

ASP Makes The Tire Gain Camber Faster. 

As the suspension compresses in turns, countering the effects of body roll and matching the needs of modern radial tires. The tire remains square with the road surface and the contact patch is improved. Grip increases.

With the ASP '69-'89 911s can now achieve modern suspension performance.

Easy To Setup Toe And Camber Independently.

Replaces the troublesome stock eccentric adjusters with simple double-adjusters.

ASP allows adjustment with vehicle weight resting on the tires making it easy to read a camber / toe gauge while turning the adjusters. Quick changes can be made track-side even if a camber gauge is not available.

  • • Upper and lower double-adjusters
  • • Rotate same direction to set toe
  • • Rotate opposite direction to set static camber
