Best*i

Best☆iトップ

■Concept

The Best*i uses the same technology and basic specifications that were originally developed for the Super*i which is RS*R's flagship model.

The basic concept and specifications used for the Best*i are the same as those used for the Super*i. However by improving the cost efficiency of the parts and oil we can offer this high-quality coilover at a reasonable price.

The Best*i is versatile and can be fitted with a wide range of vehicles such as minivans and sedans.

■Overhaul

This product can be overhauled as all parts are purely made in Japan and assembled in our own factory. We would like you to use it at the best ride feeling for a long time.

■Feature

 ・Damping force adjustment

The Best*i damper includes 36-way damping force adjustment for both front and rear coilovers. Damping force can be adjusted between hard and soft giving the driver the choice between performance or ride comfort.



 ・Mono-tube internal piston

The mono-tube piston relieves discomfort from push up due to its unique design. The steel body has an internal diameter of 40φ which is utilized for increasing oil capacity and improving heat dissipation. (Strut type vehicles have an internal diameter of 46φ)



 ・Full-length adjustable

The Best*i is designed based on the basic concept that produces enough stroke which will largely influence on drivability and ride comfort. With this "smooth suspension", it will not change the amount of stroke when car is lowered, so can keep the stable ride feeling at the corner. Lower seat doesn't come with lower seat so it will prevent the stuck of the seats and make the adjustment faster.



 ・Oil

As a result of carrying out various heat resistance tests, we have been able to develop our own original oil which is highly heat resistant and able to generate a stable damping force in any temperature.



 ・The Ti2000 spring

The Best*i uses TMC's best selling coil spring 'Ti2000' which is an extremely lightweight and durable spring. The Ti2000 comes with 3 different spring rates allowing you to choose the ride that suits you when you order. (If you don't choose the recommended rate the ride height may differ from that listed in the catalog.)



 ・Upper mount

The Best*i coilover kit uses the combination of an aluminum upper plate and a rubber bush upper mount. The pillow ball upper mount gives quicker steering response and sharper cornering whereas the rubber bush upper mount gives a more comfortable and quieter ride. The Best*i also utilizes a rubber mount with ball bearings for strut type vehicles to improve steering response.
