This version is listed for AWD models.\u003c\/p\u003e\n\u003ch3\u003eHow this kit is set up for the 2015-2021 Subaru WRX STI S4\u003c\/h3\u003e\u003cp\u003eIt is a true coilover at all four corners, so the spring and damper work as one unit front and rear. Damper bodies are 52mm front and 50mm rear. It comes with 10 kg\/mm (about 560 lb\/in) springs up front and 8 kg\/mm (about 448 lb\/in) at the rear. Damping is 1-way: a single knob with 32 settings changes rebound and compression together, which keeps tuning quick. The front top mounts are aluminum with rubber bushings, with aluminum camber plates with pillowball bushings available as an option. At the rear, the mounts are aluminum with rubber bushings (optional: aluminum with pillowball bushings).\u003c\/p\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMonotube dampers, which shed heat well and hold their damping under hard use\u003c\/li\u003e\n\u003cli\u003e32 damping settings on a single knob that sets rebound and compression together\u003c\/li\u003e\n\u003cli\u003eBolt-on install with no modifications, unless the notes below say otherwise\u003c\/li\u003e\n\u003cli\u003eRide height lowers roughly 1 to 2.5 inches below stock (SF Racing's figure) without giving up suspension travel\u003c\/li\u003e\n\u003cli\u003eSeparate lower-mount (length) adjustment, so height changes don't preload the spring\u003c\/li\u003e\n\u003cli\u003eAnodized T6-6061 aluminum top mounts, spring perches and collars for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eZinc-plated shock bodies for rust protection\u003c\/li\u003e\n\u003cli\u003eCold-wound SAE9254 spring steel\u003c\/li\u003e\n\u003cli\u003eNOK seals and Italian IP damping oil (20W)\u003c\/li\u003e\n\u003cli\u003eBuilt-in dust boots and bump stops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWho it suits\u003c\/h3\u003e\u003cp\u003eBest suited to cars that do track days, autocross or spirited back-road driving, and owners who accept a firmer ride for more control.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSF-SU08-02-TR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2015-2021 Subaru WRX STI S4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eChassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVAG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDrivetrain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAWD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper model\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrack Series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamping\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1-Way: Rebound and Compression\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDamper size (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e52mm diameter \/ 50mm diameter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpring rate (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 kg\/mm \/ 8 kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDesign (front \/ rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover \/ True Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (front)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStandard: Aluminum with Rubber Bushings \/ Optional: Aluminum Camber Plates with Pillowball Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTop mounts (rear)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStandard: Aluminum with Rubber Bushings \/ Optional: Aluminum with Pillowball Bushings\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"SPRINGRATES®","offers":[{"title":"Default Title","offer_id":67656275984685,"sku":"SF-SU08-02-TR","price":1095.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/8295\/1469\/files\/sf-racing-track-coilovers-for-2015-2021-subaru-wrx-sti-s4-vag-sf-su08-02-tr-1194295923.jpg?v=1792167124","url":"https:\/\/lowerhq.com\/products\/sf-racing-track-coilovers-for-2015-2021-subaru-wrx-sti-s4-vag","provider":"LowerHQ","version":"1.0","type":"link"}
