Stage 4 Coil Over Suspension H&R is the originator of the true coil over just a threaded tube and some sort of spring, but an actual threaded strut and shock body with a specifically designed spring. H&R coil overs are engineered for street and occasional track use, H&R Coil-Overs feature a fully-threaded shock body (not an imitation sleeve-over) that allows you to precisely dial in height adjustment to achieve optimum weight transfer, or simply get the aggressive look you've been looking for. Featuring H&R's exclusive dynamic damper technology, each shock is engineered to work in harmony with a progressive-rate spring, together creating a finely-tuned suspension system.track wh
TEAS stands for 'Tanabe Electric Active Suspension and is the counterpart of the new Sustec Pro FIVE & Sustec Pro SEVEN suspension. This compact unit is the brain behind the highly sophisticated new Tanabe suspensions. TEAS is a fully programmable dampener controller that allows for dampening force to be automatically adjusted while driving. TEAS accomplishes this by connecting and using the signal from the vehicles Speed Sensor.
Remote dampening control from within the vehicle is not a new concept by any means. In fact, many Japanese vehicles from the 1980's including the FC3S RX-7 and MA70 Supra had buttons to change dampening ; Unlike other controllers that are simply an update of this older technology, TEAS is a much larger step towards highly digital advanced suspension control and tuning through its speed sensing
TEAS active dampening control is uniquely possible due to the use of the specialized valving of the SEVEN, in conjunction with TEAS; slim, high speed actuators. These actuators change dampener settings in 1/100ths of a second, which is necessary as TEAS can continuously change settings at different speeds.
