Every set is hand-assembled in Poland with inverted front struts and inverted rear shocks for consistent damping under hard use.\u003c\/p\u003e\n\u003ch2\u003eBuilt for Racing, Time Attack, Autocross, and HPDE\u003c\/h2\u003e\n\u003cp\u003eSeparate circuits for rebound, low-speed compression, and high-speed compression let you tune platform support, curb compliance, and braking stability independently.
