FRONT REAR SPRING RATES 10k 8k UPPER MOUNT Pillowball w/ Camber Plates Pillowball STRUT DESIGN Inverted Standard Application Notes: Front Lower Mount Clevis Width = 30mm Fits 08-14 STI Sedan & Hatchback Models Only Our Dynamic Pro Drift coilovers were designed in a development project for Yellow Speed Racing by members of the Japanese "Nichiei Racing Team", Mr. Yoichi Imamura and Mr. Feng Ren Zhi. Mr. Imamura won the Japan D1 championship in 2003, 2009, 2010, and 2011 & Mr. Feng is a top D1 professional driver from Taiwan. Countless hours of development was put into these coilovers to design the best kit for drivers competing in professional level drift competitions. We are constantly testing new features, improving our design, and testing our drift spec coilovers with the input of our sponsored professional drivers to make sure that our kit lives up to our customer's expectations. YSR Drift Spec Coilovers allow you to have precision control over your vehicle during controlled slides. With the assistance of our inverted dampers (where applicable), these coilovers offer maximum performance under severe track conditions. Reinforced lower mounts, helper springs (If applicable), and specialized spring rates with matched valving derived from endless testing and research provides top level drifters with the performance and reliability they expect from a high performance drift spec suspension. MONOTUBE INVERTED DESIGN For suspension systems with front or rear MacPherson style struts, the damper will be provided with an inverted monotube design which is utilized to reduce the effect upon the damping oil and shock piston resulting from high temperature from the brake system. The inverted damper also can resist lateral stress more efficiently. The inverted damper reduces unsprung weight for quicker suspension response. For any suspension system with featuring a rear A-Arm suspension type, the rear damper shaft has been thickened to 20mm, which is able to support more side force stress, and ensure the vehicle will remain more controllable. In addition, the thickened damper shaft is more resistant to damage. The 55mm steel shock body is coated with a zinc plating for exceptional corrosion resistance. 33 LEVELS OF DAMPING ADJUSTMENT 1 Way Drift Spec Coilovers feature 33 levels of damping adjustment with the turn of a knob. Rebound & Compression Damping are controlled simultaneously. Inverted Dampers are adjusted from the bottom of the coilover. REAR SUSTECH INVERTED DAMPER DESIGN Some vehicle applications are unable to allow damping adjustment on the rear coilovers without coilover removal. With extensive testing & development, we now offer an improved rear dampening adjustment method for these vehicles. The Rear Sustech Inverted damper features a damping dial at the bottom portion of the coilover to allow simple adjustment without the need to remove any components. Sustech Inverted Dampers are included when applicable. High quality components are adopted to ensure product durability and stability. Each application is test fit and completely road tested to guarantee perfect performance and comfort.Please note that ALL of our coilovers are hand built and made to order. Please allow 2-3 weeks for delivery. **Photographs shown are stock photos; Actual items may vary in appearance or features. Please contact us for specific features of each kit.
