The factory suspension is set up to find traction at both ends for every situation. This kit is built for one job: putting power into the rear tires off the line and keeping it there.\u003c\/p\u003e\n\u003cp\u003eThe rear damper carries a bump rubber that works as an additional spring, so the kit can cope with more power and stickier tires as the car develops. Both ends are full-length adjustable, which means the stroke ratio and bump-touch timing can be changed without changing ride height — shortening the rear damper delays bump touch and increases nose-up on launch. In HKS's own launch-control testing, the drag setup was about a second quicker to 100 km\/h than stock, with less loss in the wheelspin zone. The front uses HKS's inverted strut with a dedicated outer cover, and the rear uses a lightweight billet aluminum upper plate. Straight-wound springs make rate changes easy.\u003c\/p\u003e\n\u003cp\u003eThis is a drag-only product and is not intended for street or circuit use. HKS lists it for the DB42 GR Supra 3.0 built through September 2020. Two versions are offered: 80250-AT003D without the canceler, and 80250-AT003DC with the Suspension Error Canceler included.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: full drag coilover kit, four corners\u003c\/li\u003e\n\u003cli\u003eFront: inverted strut with HKS outer cover\u003c\/li\u003e\n\u003cli\u003eRear: separated damper and spring, billet aluminum upper plate, bump rubber acting as an additional spring\u003c\/li\u003e\n\u003cli\u003eDamping adjustment: 30 steps front and rear\u003c\/li\u003e\n\u003cli\u003eFull-length adjustable bodies: change stroke ratio without changing ride height\u003c\/li\u003e\n\u003cli\u003eSpring rates: front 59 N\/mm (6 kgf\/mm), rear 98 N\/mm (10 kgf\/mm)\u003c\/li\u003e\n\u003cli\u003eSpring free length: front 200 mm, rear 250 mm\u003c\/li\u003e\n\u003cli\u003eRide height: front −22 mm default (−17 to −61 mm), rear −20 mm default (−12 to −75 mm)\u003c\/li\u003e\n\u003cli\u003e80250-AT003DC: Suspension Error Canceler included\u003c\/li\u003e\n\u003cli\u003eMade in Japan\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e80250-AT003D: two front inverted struts, two rear dampers, front and rear springs, mounting hardware and HKS installation manual\u003c\/li\u003e\n\u003cli\u003e80250-AT003DC: everything in 80250-AT003D plus the HKS Suspension Error Canceler (45012-AT001)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRequired extra for 80250-AT003D:\u003c\/strong\u003e the \u003ca href=\"https:\/\/speedlogicauto.com\/products\/hks-suspension-error-canceler-toyota-gr-supra-a90-a91\"\u003eHKS Suspension Error Canceler 45012-AT001\u003c\/a\u003e, sold separately, to stop the suspension fault message once the factory adaptive dampers are removed.
