Like TL-ONE, TL-PRO uses a true rear coilover configuration for improved motion ratio, rear grip, and predictability under load.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Racing, Time Attack, Autocross, and HPDE\u003c\/h2\u003e\n\u003cp\u003eCombined with adjustable sway bars, independent rebound, low-speed compression, and high-speed compression let drivers fine-tune mechanical balance and platform support without unnecessary harshness — critical for high-grip tires, aero load, and long sessions. Every kit can also be valved specifically for street use — the compliance needed for competent track use often makes for a comfortable street ride, since controlling the platform better also controls body motion better on the street.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e46mm monotube dampers, true rear coilover configuration\u003c\/li\u003e\n\u003cli\u003e20-click rebound, 34-click low-speed compression, 18-click high-speed compression (true 3-way)\u003c\/li\u003e\n\u003cli\u003eRide Height Adjustment (fixed-length shock bodies, matched to your target ride height)\u003c\/li\u003e\n\u003cli\u003eFront and rear 2-hole adjustable sway bars with adjustable end links\u003c\/li\u003e\n\u003cli\u003eSpring\/valving baselines: 20k F\/8k R (Track\/Race), 16k F\/7k R (Street\/Track), 14k F\/6k R (Comfort), 16k F\/10k R (Drift)\u003c\/li\u003e\n\u003cli\u003eCVP + PVP dyno graphs included with every kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction \u0026amp; Hardware\u003c\/h2\u003e\n\u003cp\u003eCNC-machined top hats and bottom mounts pair with pillowball\/spherical bearing top hats and electroplated shock bodies for long-term corrosion resistance.
