RedShift Street S1 Coilovers (Value Kit) 2017-21 Mercedes C63 S AMG Coupe (C205) [RJ-27-STREET_S1]

RedShift Street S1 Coilovers (Value Kit) — real coilover performance, set up and shipped by RedShift, at an entry price.

The Street S1 is our Value Kit for the 2017-21 Mercedes C63 S AMG Coupe (C205): a 32-way damping-adjustable monotube coilover that we inspect, set up and ship from our shop. Full-length ride-height adjustment, standard spring rates chosen for a firm but livable street ride, and everything included — springs, mounts, height adjusters and tools. Nothing additional to purchase.

Spring upgrades (select above): higher or lower spring rates, with standard springs or Swift springs, can be added when you order. If you want the kit built to your own spring rates with a valving choice, see the RedShift Street Custom; for revalved race damping see the RedShift Comp 1W.
