Fortune Auto's Generation 8 500 Series is their entry point into true coilover performance, built around a High Flow Digressive Piston that balances daily comfort against real track capability rather than forcing a choice between the two. Digressive piston tuning gives you firm low-speed compression and rebound control — exactly what keeps body roll, dive, and squat in check during spirited driving — while staying supple over fast, sharp inputs like potholes and expansion joints.

Every damper is custom built and dyno tested, backed by a 5-year limited manufacturer's warranty, with 24-step external adjustment so you can dial in exactly the ride you want. T6 6061 aluminum mounts and camber plates keep the whole assembly lightweight and precise, and everything is rebuildable and revalveable at Fortune Auto's Richmond, VA facility — with modularity to upgrade to a 2-way or 3-way canister down the road. You genuinely shouldn't need to buy another set of coilovers after this.
