Every set ships with inverted front struts and rear shocks, 20-click rebound adjustment, and Independent Ride Height and Travel Adjustment for a true target ride height without riding the bump stops.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Racing, Time Attack, Autocross, and HPDE\u003c\/h2\u003e\n\u003cp\u003eThe A90's stock geometry and heavy curb weight 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\u003eInverted front struts \/ inverted rear shocks, 36mm piston \/ 40mm body\u003c\/li\u003e\n\u003cli\u003e20-click rebound adjustment (1-way)\u003c\/li\u003e\n\u003cli\u003eIndependent Ride Height and Travel Adjustment\u003c\/li\u003e\n\u003cli\u003eFront 8kg \/ Rear 16kg linear springs (standard; custom rates available)\u003c\/li\u003e\n\u003cli\u003eSpherical bushing top hats\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\u003eCheck valves manage the split between compression and rebound so the car stays planted at low speed without losing bump compliance.
