These Acura NSX coilovers are engineered to pair street comfort with canyon and track capability, giving you the stance, handling, and adjustability you've been chasing without compromising daily driveability. Whether you track your NA1 NSX on weekends or log daily miles, this NA1 coilover kit dials in ride height and damping to match how you actually use the car.\u003c\/p\u003e\u003cp\u003eGP1 Series Technology: The GP1 uses a digressive piston design that delivers firmer low-speed damping for flatter cornering and sharper response, while softening at higher shaft velocities to absorb bumps. If you want more control than a linear coilover without sacrificing ride quality, this is the set.\u003c\/p\u003e\n\u003cp\u003eEvery GP1 set features a monotube damper with 32 levels of damping adjustment, so you can tune ride quality to match the road, the weather, or your driving mood. Full-length ride-height adjustment separates preload from ride height — meaning you can drop the NSX NA1 to the height you want while preserving spring travel and shock stroke. Riaction coilovers for the 1990-2005 Acura NSX are fully rebuildable and backed by a 2-year warranty, making the GP1 a long-term suspension investment rather than a disposable upgrade.\u003c\/p\u003e\n\u003ch3\u003eGP1 Series Technology\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMonotube linear damper with seamless 52mm electroplated carbon steel body\u003c\/li\u003e\n\u003cli\u003e32-level damping adjustment (1-Way)\u003c\/li\u003e\n\u003cli\u003e44mm CNC-machined 6061 aluminum high-flow piston\u003c\/li\u003e\n\u003cli\u003e20mm piston rod for MacPherson applications \/ 14mm for non-MacPherson\u003c\/li\u003e\n\u003cli\u003eSAE9254 cold-wound linear main springs\u003c\/li\u003e\n\u003cli\u003eMulti-thickness valving shims for consistent damping\u003c\/li\u003e\n\u003cli\u003ePolyurethane oil seals and 7.5W suspension fluid\u003c\/li\u003e\n\u003cli\u003eLow-gas-pressure design for improved compliance\u003c\/li\u003e\n\u003cli\u003eFully rebuildable — built to be serviced, not replaced\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFull-length ride-height adjustment (preload-independent)\u003c\/li\u003e\n\u003cli\u003e32 levels of damping adjustment\u003c\/li\u003e\n\u003cli\u003eOptional Swift Springs upgrade (sold separately)\u003c\/li\u003e\n\u003cli\u003e2-year limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe GT1 uses a linear piston — good low-speed control for body roll, turn-in, and weight transfer, with damping that follows a predictable curve through bumps. That balance makes it the right call for street, canyon, and occasional track days. The GP1 runs a digressive piston that sharpens low-speed response with higher initial resistance for flatter cornering, then softens at higher shaft velocities — a blow-off behavior that relieves harshness over potholes, curbs, and expansion joints. The GP1 is built for track-focused driving, autocross, and aggressive street use where you want the extra bite under load.\u003c\/p\u003e\n\u003cp style=\"margin-top: 1.25em;\"\u003eShort version: choose GT1 if you want the best daily-street-track balance — typically in stock and ship-ready. Choose GP1 if you want tighter response under load and don't mind the lead time on a built-to-order digressive tune.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003ctable class=\"table table-striped table-primary\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eHA-032-SS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Name\u003c\/td\u003e\n\u003ctd\u003eRiaction GP1 Coilovers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVehicle\u003c\/td\u003e\n\u003ctd\u003e1990-2005 Acura NSX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChassis Code\u003c\/td\u003e\n\u003ctd\u003eNA1\/NA2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdjustment Type\u003c\/td\u003e\n\u003ctd\u003e1-Way\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRide-Height Adjustable\u003c\/td\u003e\n\u003ctd\u003eYes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Front\u003c\/td\u003e\n\u003ctd\u003e10 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSpring Rate - Rear\u003c\/td\u003e\n\u003ctd\u003e10 Kg\/mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop Mounts - Front\u003c\/td\u003e\n\u003ctd\u003eOEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTop Mounts - Rear\u003c\/td\u003e\n\u003ctd\u003eOEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCamber Plates - Front\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCamber Plates - Rear\u003c\/td\u003e\n\u003ctd\u003eNo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuspension Design - Front\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSuspension Design - Rear\u003c\/td\u003e\n\u003ctd\u003eTrue Coilover\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch5\u003eVehicle Fitment\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1990 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1991 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1992 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1993 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1994 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1995 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1996 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1997 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1998 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e1999 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2000 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2001 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2002 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2003 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2004 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003cli\u003e2005 Acura NSX (NA1\/NA2)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Riaction","offers":[{"title":"Default Title","offer_id":40980315734076,"sku":"HA-032-SS-GP1","price":1389.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0000\/2183\/files\/riaction-gp1-coilovers-for-1990-2005-acura-nsx-na1-na2-ria-nsxdg-gp1-1194411699.jpg?v=1767822338","url":"https:\/\/www.springrates.com\/products\/riaction-gp1-coilovers-for-1990-2005-acura-nsx-na1-na2","provider":"SPRINGRATES®","version":"1.0","type":"link"}
