Every set ships with 20-click rebound adjustment, standard rear reservoirs, and 2.5\" linear springs for consistent damping through long sessions.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Racing, Time Attack, Autocross, and HPDE\u003c\/h2\u003e\n\u003cp\u003eThe S13's light chassis and balanced layout reward a coilover that controls weight transfer without going harsh. TL-ONE is valved around that balance, and 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\u003eElectroplated, rebuildable monotube shocks with individual replacement parts available\u003c\/li\u003e\n\u003cli\u003e20-click rebound adjustment (1-way)\u003c\/li\u003e\n\u003cli\u003eStandard rear reservoirs for added oil volume and heat management\u003c\/li\u003e\n\u003cli\u003e2.5\" linear springs\u003c\/li\u003e\n\u003cli\u003eSpherical or rubber top mounts; Micro Cellular Polyurethane bump stops\u003c\/li\u003e\n\u003cli\u003eSpring rates finalized in consultation with you before production begins\u003c\/li\u003e\n\u003cli\u003eLinear \/ digressive valving; CVP + PVP dyno graphs included with every kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eConstruction \u0026amp; Hardware\u003c\/h2\u003e\n\u003cp\u003eCheck valves manage the split between compression and rebound so the car stays planted at low speed without losing bump compliance. 46mm monotube bodies are electroplated for corrosion resistance, and every kit is fully rebuildable — replacement internals are available as tires, alignment, or use case change.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cp\u003eNissan 240SX, Silvia and 180SX (S13), 1989–1994.\u003c\/p\u003e\n\u003c\/section\u003e\n\u003csection class=\"tlone-faq\" id=\"tlone-faq\"\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat's the lead time?\u003c\/summary\u003e\u003cp\u003e4–6 weeks, built to order.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat's the warranty?\u003c\/summary\u003e\u003cp\u003e6 months — void for track damage, covers unreasonable wear and defects only.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs this streetable?\u003c\/summary\u003e\u003cp\u003eYes — every kit can be valved specifically for street use if that's your preference.
