Designed by D1GP driver and 326POWER CEO Mitsuru Haruguchi, every Chakuriki kit is built to your exact specifications. Choose your colors, spring rates, and upgrade options for a coilover setup engineered specifically for your BMW 3 Series.\u003c\/p\u003e\n\u003ch3\u003eChakuriki or Bucchigiri?\u003c\/h3\u003e\n\u003cp\u003eBoth are the same 326POWER damper, built to order in Japan with the same seven anodize colors and the same 26-step damping. Bucchigiri adds a matched helper spring at every corner, plus the longer shock stroke and dedicated valving that requires, so the main spring stays supported at full extension and the car stays settled over crests and dips at low ride height. It sits one price rung higher at every rate. If you run a lot of droop or sit very low, Bucchigiri is worth it. If not, Chakuriki is the same kit without the helper.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"\/collections\/326power-bucchigiri-coilovers\"\u003eSee the 326POWER Bucchigiri range\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy Choose Chakuriki?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\nFully Customizable: Choose your own colors for adjusters, top mounts, springs, brackets, and dust boots\u003c\/li\u003e\n\u003cli\u003e\nCustom Spring Rates: Choose 12K \/ 20K \/ 32K at the front, with the rear rate matched by 326POWER and the dampers valved to suit\u003c\/li\u003e\n\u003cli\u003e\n26-Step Damping Control: Precise click adjusters for fine-tuning rebound and compression\u003c\/li\u003e\n\u003cli\u003e\nExtreme Drop Capability: Independent ride height and preload adjustment maintains full damper travel at the lowest settings\u003c\/li\u003e\n\u003cli\u003e\nBuilt to Order in Japan: Each kit is assembled to your specifications by 326POWER\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to Build Your Coilovers\u003c\/h3\u003e\n\u003cp\u003eSTEP 1: Springs\u003cbr\u003e\nBy default, Chakuriki coilovers are fitted with 326POWER's Charabane springs. Upgrade to Majibane springs, manufactured by Swift, for a more progressive spring setup.\u003c\/p\u003e\n\u003cp\u003eSTEP 2: Spring Color\u003cbr\u003e\nCharabane springs come in Pink, Green, Gunmetal, or Yellow. Majibane springs come in Green, Pink, or Gold.\u003c\/p\u003e\n\u003cp\u003eSTEP 3: Kit Colors\u003cbr\u003e\nChoose a color for each aluminum part: damping adjuster, upper mount, upper sheet, spring lock sheet, bracket lock sheet, and bracket. All seven colors are free, so pick one throughout or mix them.\u003c\/p\u003e\n\u003cp\u003eSTEP 4: Dust Boot Color\u003cbr\u003e\nBlack is included. Blue, Green, Pink, and Yellow are available as an upgrade.\u003c\/p\u003e\n\u003cp\u003eSTEP 5: Helper Springs\u003cbr\u003e\nHelper springs keep the main spring supported at full extension when running a lot of droop. Choose Charabane or Swift Majibane, front, rear, or both ends.\u003c\/p\u003e\n\u003cp\u003eSTEP 6: Helper Spring Colors\u003cbr\u003e\nIf you added helper springs, choose the spring color and the collar color.\u003c\/p\u003e\n\u003cp\u003eSTEP 7: 360 Bearing\u003cbr\u003e\nThe 360 Bearing sits between the spring and the locking collar so the spring rotates freely and binds less when steering. Available upper, lower, or both, at either end.\u003c\/p\u003e\n\u003cp\u003eSTEP 8: Super Thrust Sheets\u003cbr\u003e\nThrust sheets reduce spring friction and noise when turning, which matters most with stiffer rates. Colors are assigned at random by 326POWER Japan.\u003c\/p\u003e\n\u003cp\u003eSTEP 9: Hex Lock Seat\u003cbr\u003e\nAn upgraded lock seat in Standard or High Spec.\u003c\/p\u003e\n\u003cp\u003eNeed a spring rate combination that is not listed?
