Free Shipping ANYWHERE in North America! Including the lower 48 states, Canada, Alaska, Hawaii, Puerto Rico, Mexico and the Caribbean!*

Taking the knowledge and experience learned with the 4000 Series of dampers, AST is now building the new 5000 Series dampers. One key design feature of the 5000 Series are their inverted strut design, which makes for a very stiff strut assembly, providing better suspension geometry under heavy lateral and braking loads seen in a road course environment. Cygnus Performance Carries the full line of AST 5000 series coilovers including the single adjustable 5100's, the double adjustable 5200's and triple adjustable 5300's.

Spring rates for AST coilovers are metric. For those who think in pounds this will help:
5 kg/mm = 279.987073 lbs/in
6 kg/mm = 335.984488 lbs/in
7 kg/mm = 391.981902 lbs/in
8 kg/mm = 447.979317 lbs/in
9 kg/mm = 503.976731 lbs/in
10 kg/mm = 559.974146 lbs/in
11 kg/mm = 615.971561 lbs/in
