The AST 5100 Street TCO suspension is built for exactly that. It lets you maximize grip by controlling both rebound damping and ride height, so the car can be dialed in for the road you actually drive. The kit includes springs and is designed to run the factory top mounts. Front and rear both use a true coilover layout, prioritizing adjustability and consistent, predictable handling.\u003c\/p\u003e\n\u003cp\u003eThe baseline damping settings and spring rates come out of AST's own development and testing program. From there, individual preference is a matter of turning the rebound knob or changing the ride height. Rebound adjustment controls how quickly the damper returns to extension, and with 12 distinct positions each click gives a different feel and a different driving experience.\u003c\/p\u003e\n\u003cp\u003eAST uses a high-pressure monotube design. The large piston gives the damper the authority to control rebound properly, and because a monotube does not aerate or foam the valving stays responsive. The additional gas pressure adds resistance when driving conditions demand it. The dampers are rebuildable, so if anything is damaged or worn it can be addressed at a certified AST service center rather than replaced.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAST 5100 Street TCO series — one-way adjustable (rebound)\u003c\/li\u003e\n\u003cli\u003eHigh-pressure inverted monotube damper design\u003c\/li\u003e\n\u003cli\u003e12 distinct rebound adjustment positions\u003c\/li\u003e\n\u003cli\u003eRide height adjustable independently of the damping setting\u003c\/li\u003e\n\u003cli\u003eSprings included in the kit\u003c\/li\u003e\n\u003cli\u003eDesigned to run the OEM top mounts — no aftermarket camber plates required\u003c\/li\u003e\n\u003cli\u003eTrue coilover (spring over damper) layout front and rear\u003c\/li\u003e\n\u003cli\u003eLarge monotube piston with no aeration or foaming, for more responsive valving\u003c\/li\u003e\n\u003cli\u003eBaseline damping and spring rates set from AST's development and testing program\u003c\/li\u003e\n\u003cli\u003eRebuildable and serviceable at a certified AST service center\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFront and rear AST 5100 Street TCO coilover assemblies\u003c\/li\u003e\n\u003cli\u003eSprings (included — front and rear)\u003c\/li\u003e\n\u003cli\u003eTop mounts are not supplied — the kit is designed to reuse the factory top mounts\u003c\/li\u003e\n\u003cli\u003eComplete kit as supplied by AST Suspension; see the installation instructions for the full bill of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-wheel alignment — mandatory.\u003c\/strong\u003e Camber, caster and toe all change when ride height changes.
