RS-R Best-I Active Coilover Kit Lexus LC500 | LC500h 2017+

$3,999.00

RS-R

Model #XBIT981MA


Shopper Award

New coilover series that can be used with AVS system equipped on some models of Lexus and Toyota cars is released. AVS system does not function on current aftermarket shocks and coilovers. But the i SHOCK Active series retains factory controls. Now the factory actuator can be used on an aftermarket coilover so the dampening and control systems still function. Damper force non-adjustable model "RS-R Basic i Active", damper-force adjustable model "RS-R Best i Active" and extreme low down look with AVS system "RS-R Black i Active"are now on sale.

The RS-R Coilover are all Monotube hand assembled systems specifically designed to improve ride quality, performance, and comfort. Utilizing components such as; laser cut upper mounts, hand welded lower brackets, vehicle specific valving, are all assembled by hand to ensure quality and detail.

Features:

  • Damper force adjustment of the Best i Active and Black i Active can be adjusted by the dial at the bottom of the shock. (Damper force of the Basic i Active cannot be adjusted. Dial doesn't come with it.)
  • The mono-tube piston relieves discomfort from push up due to its unique design. The steel body has an internal diameter of 40mm which is utilized for increasing oil capacity and improving heat dissipation.
  • Best Active SHOCK series has enough travel that will be influence on ride feeling. This gives the driver the freedom to lower the ride height without sacrificing ride comfort or steering response (as adjusting the lower spring seat can). By shortening the length of the coilover without affecting the spring rate, the piston stroke can be maintained giving the maximum ride comfort. The ride height can quickly and easily be adjusted by the driver.The Black?i has been developed based on a completely different concept from the conventional i SHOCK series. Meeting the regulation for lowest ride height, Black i Active provide wider range of setting.The Black i is specially designed as short stroke & short case shock. By designing the damping force and spring rate harder,it gives the driver sharper handling and more control while maintaining low form.
  • Ti2000' which is an extremely lightweight and durable spring is used for the series. Ti2000 spring for the Best*i and Basic*i offers 3 spring rate options allowing you to choose the driving situation that suits you. (If you don't choose the recommended rate, the ride height may differ from the data listed in the catalog). We offers the spring rate option for Ti2000 straight spring for Black*i Active from the spring rate list.
  • 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.

  • Recommended Adjustable Range Hybrid: F/+20-40 R/+10-35(mm)
  • Recommended Adjustable Rance Non-Hybrid: F/+20-35 R/+20-35(mm)
  • Recommended Spring Rate (Kg/mm): F/10.0K R/5.0K

What is RS-R?

Racing Studio-R or RS-R is globally recognized for its top-of-the-line high-performance suspension products for both daily drivers and the motorsports industry. RS-R began life as a wholesale distributor in Osaka, Japan. Unsatisfied with the quality of parts they were able to obtain, RS-R started its own factory in September of 1980 and sought out new ways to take driving to a new level of comfort with style and performance in mind. In 1998, the company established distribution in America and the rs-r.com website. In 2011, RS-R opened RS-R USA, their American subsidiary. They are continuously working to establish their brand and reputation in America.

RS-R achieves that by actively embracing the trial of motorsports competition such as drag races, N1, sprints, drifting, rallies, and Super GT.
