HKS SKU: 80450 PN: 21004-AT002

This kit has been developed as a result of the knowledge and experience gained from excessive testing in the D1 Drift machines and Tsukuba Circuit time attack machines. As the kit uses the same bore pistons no additional machining work such as boring or honing are required for installation. Once installed hp and torque output will be increased all throughout the power band and internals will be reinforced to reliably handle up to 550ps or 50kgf/m!!
