It pairs 46mm-piston front dampers and upside-down (inverted) 36mm piston \/ 40mm body rear dampers with 20-click rebound adjustment and front camber plates.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Racing, Time Attack, Autocross, and HPDE\u003c\/h2\u003e\n\u003cp\u003eThe F30 is a stiff, well-balanced modern chassis that responds immediately to better damping and a camber-adjustable front end. 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\u003eMonotube damper bodies, electroplated and fully rebuildable\u003c\/li\u003e\n\u003cli\u003e20-click rebound adjustment (single-adjustable) with digressive valving\u003c\/li\u003e\n\u003cli\u003eFront dampers 46mm piston; upside-down (inverted) rear dampers 36mm piston \/ 40mm body for added strength and reduced unsprung mass\u003c\/li\u003e\n\u003cli\u003eFront camber plates; rubber or pillowball rear top mounts\u003c\/li\u003e\n\u003cli\u003eLinear-rate springs specified to your car, with Swift spring option\u003c\/li\u003e\n\u003cli\u003eSpring rates finalized in consultation with you before production begins\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 for strong low-speed platform control.
