Part # astACU-T2401S

Taking the knowledge and experience learned with the 4000 Series of dampers, AST is now building the new AST 5100 Series Coilovers dampers. One key design feature of the AST 5100 Series Coilovers is their inverted strut design, which makes for a very stiff strut assembly, giving better suspension geometry under heavy lateral and braking loads seen in a road course environment.
