Every set ships with inverted front struts and rear shocks, 20-click rebound adjustment, front camber plates, and dual height 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 GR Corolla's turbocharged three-cylinder and rally-bred all-wheel drive 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 and rear shocks, 36mm piston \/ 40mm body, rebuildable monotube design\u003c\/li\u003e\n\u003cli\u003e20-click rebound adjustment (1-way)\u003c\/li\u003e\n\u003cli\u003eDual height adjustment with a true coilover rear\u003c\/li\u003e\n\u003cli\u003eFront camber plates and pillowball upper mounts\u003c\/li\u003e\n\u003cli\u003eSpring rates finalized in consultation with you before production begins\u003c\/li\u003e\n\u003cli\u003eDigressive 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\u003eInverted front struts increase rigidity under load and reduce unsprung weight, while check valves manage the split between compression and rebound for strong low-speed platform control.
