Tein Circuit Master Racing Damper With existing full-length adjustable dampers, various vibration stresses might cause bracket lock to loosen in rare occasions. SUPER RACING has 'Conical Spring Washer' inserted between a bracket lock and a lower bracket, to effectively prevent loosening of a bracket lock even when circuit-driving intensively.

Tein Circuit Master Racing Damper External tank mounted at the bottom of shell case turns in the direction of thrust, for finer full-length adjustment.
* Wishbone/Multi-link Type Only.

Pillow upper mount is set in each model for controlling the compliance, for realization of direct driving feel and handling incomparable with the original one.

Tein Circuit Master Mono-tube shell case is adopted to enable very fine control of the machine and aggressive yet detailed communication with the road surface. It generates and maintains very stable damping force, which even stands the intensive and repeated runs on the circuit, reacting to the tiniest data from the road surface.

Tein Circuit Master Racing Damper Full-length adjustment system with movable lower bracket has been adopted, which enables the separate adjustment of the ride-height and pre-load

Tein Circuit Master Racing Damper For finer settings, total of 256 different kinds of damping force settings (16 levels for compression x 16 levels for rebound) are available, by adding the systems both at base valve and piston rod. Use of specially shaped needle valve enables linear damping force adjustment at each and every 16 levels.

Tein Circuit Master Racing Damper All threading parts are coated with specially formulated Fluorine, to prevent adherence and rust. Electroless nickel plating combined with clear painting is applied to lower brackets.
*Strut type only.

Tein Circuit Master Racing Damper Inverted steel shell case is used for strut types, for which the side rigidity is inevitable. Linear damping force, which is one of the advantages of mono-tube system, is just as same as the regular shell case.

Tein Circuit Master Racing Damper are Light weight aluminum shell case is used for wishbone and/or multi-link type suspension, for superior heat liberation. Furthermore, the surface is treated with specially formulated hard black Alumite for improved durability.

Tein Circuit Master Racing Damper Upper spring seat is used for wishbone and/or multi-link type to move springs and dampers coaxially. This enables springs to stroke at proper rates without twisting, and dampers to stroke smoother.
