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\u003eFront inverted struts (36mm piston), rear dampers (46mm piston)\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 damper)\u003c\/li\u003e\n\u003cli\u003eFront camber plates, rear remote compression canisters with quick disconnect\u003c\/li\u003e\n\u003cli\u003eTrack baseline springs: Front 10–12kg \/ Rear 16kg (customizable)\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\u003eRear remote compression canisters increase oil volume for better heat management and damping consistency under sustained track load, with quick-disconnect fittings for clean mounting and easy service.
