TEIN specifies 9 kgf\/mm front and 11 kgf\/mm rear spring rates for this application.\u003c\/p\u003e\n\u003cp\u003eMono Sport steps up to a mono-tube damper, where the oil and gas are kept apart so the oil can't foam under hard use. On strut cars TEIN uses its Upright Strong Tube design, which gives much of the side stiffness of an inverted strut without the extra sealing. Height is set by full-length adjustment and the 16-level adjuster uses TEIN's ADVANCE M.S.V. valve, which TEIN says gives a much wider spread between the softest and firmest settings.\u003c\/p\u003e\n\u003cp\u003eThe damper bodies get TEIN's two-layer powder coat, and the height-adjustment threads are protected by TEIN's low-friction ZTP coating, which resists rust and stone chips and helps stop the spring seats seizing. TEIN springs are cold-formed from SAE9254 spring steel and powder coated, and TEIN designs them to resist sagging over time.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamper type:\u003c\/strong\u003e Mono-tube, separate gas and oil chambers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight adjustment:\u003c\/strong\u003e Full-length (case-length) adjustable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping adjustment:\u003c\/strong\u003e 16 levels (compression and rebound together)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring rate, front:\u003c\/strong\u003e 9 kgf\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring rate, rear:\u003c\/strong\u003e 11 kgf\/mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRide height as supplied, front:\u003c\/strong\u003e approx. 35 mm lower than standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRide height as supplied, rear:\u003c\/strong\u003e approx. 25 mm lower than standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTEIN recommended height range, front:\u003c\/strong\u003e 25 to 45 mm below standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTEIN recommended height range, rear:\u003c\/strong\u003e 15 to 35 mm below standard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEDFC motor kit:\u003c\/strong\u003e EDK05-12120 (sold separately)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop mounts:\u003c\/strong\u003e Vehicle-specific top mounts included on most cars (rubber or pillow-ball)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e GSQ74-71AS3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eSpring rates and ride heights are TEIN's application data.

Set the ride height on the bench by screwing the damper body in or out of its lower bracket, then fine-tune on the car. TEIN pre-tightens the lower bracket lock rings only, so they must be fully tightened at fitting and checked regularly. Never shorten the body beyond TEIN's stated range. Tighten the top nut with a torque wrench while holding the piston rod on its flats; over-tightening can damage the adjuster. Leave suspension arm bolts loose until the car is back on its wheels, then torque them at normal ride height so the bushes aren't preloaded. TEIN advises lowering by no more than 30-40 mm to start with, keeping the front level with or 5-10 mm lower than the rear. Let the springs settle for a few days, recheck the height and lock rings, then have a full four-wheel alignment done. Fitting needs spring compressors (where strut assemblies are rebuilt), a torque wrench and a good understanding of the car's suspension. We recommend professional fitting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle-specific notes from TEIN:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRear: the original spring insulator needs to be modified.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eUpgrade Further\u003c\/h3\u003e\n\u003cp\u003eLowering changes the anti-roll bar geometry.

Check your chassis code, year and trim against that list, along with any notes under it. If you're unsure, send us your registration or VIN before ordering and we'll confirm.\u003c\/p\u003e\n\u003ch3\u003eHow low will my Lexus IS250 GSE30 GSE30L go?\u003c\/h3\u003e\n\u003cp\u003eAs supplied, TEIN's data puts the car approx. 35 mm lower than standard at the front and approx. 25 mm lower than standard at the rear. TEIN recommends staying within 25 to 45 mm below standard at the front and 15 to 35 mm below standard at the rear. Wheels, tyres and the car's condition all affect the final height.\u003c\/p\u003e\n\u003ch3\u003eCan I adjust the damping?\u003c\/h3\u003e\n\u003cp\u003eYes. The 16-level adjuster changes compression and rebound together: 0 is the stiffest setting and 16 the softest. Start from TEIN's recommended setting and change it a few clicks at a time.\u003c\/p\u003e\n\u003ch3\u003eDoes it work with TEIN EDFC?\u003c\/h3\u003e\n\u003cp\u003eYes. You'll need TEIN's EDFC5 controller kit plus motor kit EDK05-12120 for this car, both sold separately. EDFC lets you change damping from inside the car.\u003c\/p\u003e\n\u003ch3\u003eAre top mounts included?\u003c\/h3\u003e\n\u003cp\u003eTEIN supplies vehicle-specific top mounts where the car needs them. On some models the original mounts are reused, so check them for wear before fitting.\u003c\/p\u003e\n\u003ch3\u003eDo I need a wheel alignment after fitting?\u003c\/h3\u003e\n\u003cp\u003eYes. Changing ride height alters camber and toe, so have a full four-wheel alignment done once the springs have settled and the height is final.\u003c\/p\u003e\n\u003ch3\u003eAre TEIN coilovers road legal in the UK?\u003c\/h3\u003e\n\u003cp\u003eCoilovers can be used on UK roads as long as the car stays roadworthy: keep a sensible ride height, enough clearance and correctly aimed headlights. Modifying your suspension should be declared to your insurer.\u003c\/p\u003e\n\u003ch3\u003eCan Mono Sport dampers be serviced?\u003c\/h3\u003e\n\u003cp\u003eYes. Mono-tube dampers like Mono Sport can be overhauled and revalved by TEIN. TEIN suggests a service every 2-3 years or 30,000-40,000 km on the road, or yearly with regular track use.\u003c\/p\u003e\n\u003ch3\u003eWhat warranty do TEIN coilovers come with?\u003c\/h3\u003e\n\u003cp\u003eTEIN UK covers its suspension for 12 months from the date of purchase against defects in materials and workmanship.
