Tanabe Sustec Pro SEVEN Coilover 2007+ Lexus GS350 (RWD) - P/N: TSE7112 Product Model: TAN-TSE7112 Sustec Pro SEVEN is an all new adjustable coilover suspension that features a wide array of all new circuit developed technology that has not been available until now. SEVEN advances the technologies and greatest strengths of previous high performance Tanabe suspensions like the RR & DD even further. While similar in appearance, the SEVEN is completely different from any suspension currently available. The difference lies within the suspension itself and its highly unique internal construction and slide valve technology. The new slide valve technology allows a great range of adjustability and function from both sides of the performance spectrum. (comfort to pure competitive motorsports use) When used with the new TEAS electronic active suspension controller, the wide range of dampening force is accessible through the touch of a button, and is fully programmable to automatically adjust dampening rates according to the speed you drive. In addition to TEAS, SEVEN is also available as a special "Hard Driving" version, for strictly motorsports use.
