The R designation sits above the HIPERMAX S in the HKS lineup. Firmer spring rates, stiffer damping, calibrated for drivers who take the FT86 to the track regularly. The asymmetric 9K\/10K spring rate is the same logic applied to the second-generation chassis: the stiffer rear rate supports the platform's weight distribution in high-load cornering.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecs \u0026amp; Highlights\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e9K front \/ 10K rear spring rates\u003c\/li\u003e\n\u003cli\u003ePerformance-oriented damper valving\u003c\/li\u003e\n\u003cli\u003eHeight adjustable\u003c\/li\u003e\n\u003cli\u003eDesigned for track-focused use on the FA20 chassis\u003c\/li\u003e\n\u003cli\u003eAsymmetric spring rates for platform-specific balance\u003c\/li\u003e\n\u003cli\u003eFitment: 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003e9\/10 kgf\/mm, 46mm Inverted Strut, -20 to -50mm\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe AT001 runs 9 kgf\/mm (504 lbf\/in) front and 10 kgf\/mm (560 lbf\/in) rear, the same rates as the second-generation AT006 application. The 46mm inverted strut design provides better camber curve control at the higher spring rates than a conventional strut would. Ride height adjustment is -20mm to -50mm front and -15mm to -45mm rear. The asymmetric 9\/10 spring rate was derived from HKS's time attack testing on the FT86 platform, where a stiffer rear relative to front was found to produce the most consistent neutral handling balance across a full track session.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/files\/6b2fce094c27fe476f061b8128336e4c_7fd8d61c-2845-41ec-8027-70a2e8cfb1b0.jpg?v=1772084617\" alt=\"HKS Hipermax R Coilovers (9K Front \/ 10K Rear) - 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\" style=\"max-width: 100%; height: auto; display: block; margin: 20px 0;\"\u003e \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0743\/4122\/0668\/files\/2e63428e3aa9e3699d3d02d48222de54_6659ea75-7b68-4d2a-803b-9e9bbfc17c9c.jpg?v=1772084618\" alt=\"HKS Hipermax R Coilovers (9K Front \/ 10K Rear) - 2013-2021 Scion FR-S \/ Subaru BRZ \/ Toyota 86\" style=\"float: left; width: 40%; max-width: 300px; height: auto; margin: 0 20px 16px 0;\"\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eAsymmetric Spring Rates from HKS Time Attack Testing\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe FA20 chassis in the original FR-S and BRZ is one of the best-balanced platforms for coilover work. The neutral weight distribution and low center of gravity respond well to proper spring and damper calibration. The Hipermax R takes advantage of that by providing rates that allow the suspension to work correctly through the full range of performance driving inputs.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003ePerformance Coilover, Not a Street Compromise\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Hipermax R does not try to be compliant for daily driving. It is a performance coilover for an owner who has decided what the car is for. Ride quality on imperfect surfaces is firm. On smooth tarmac and at the track, the R delivers handling that justifies its position in the HKS lineup. Four-wheel alignment after installation is required.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003ch4\u003e\u003cstrong\u003eThe FT Breakdown\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eThe Hipermax R at 9K\/10K is HKS's recommendation for FR-S, BRZ, and 86 owners who track their car regularly. The HIPERMAX S is the better choice for mixed-use. If the car goes to autocross events, time trials, or track days with any regularity, the R is the correct specification. The 9\/10 kgf\/mm asymmetric rates derived from HKS time attack testing of the first-generation FT86 platform are a specification that has been validated across hundreds of track sessions by HKS and their affiliated teams. When a company that campaigns race cars tests a suspension setup on the same platform you are working with, the spring rate recommendation carries a different level of authority than a calculation from first principles.\u003c\/p\u003e\n\u003cdiv style=\"clear: both;\"\u003e\u003cbr\u003e\u003c\/div\u003e","brand":"HKS","offers":[{"title":"Default Title","offer_id":52621264322840,"sku":"HKS80310-AT001","price":804.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/4514\/4856\/files\/s38iuip0md77_2acd19db-cce4-4291-bbd9-7d3fab416c3a.jpg?v=1788747626","url":"https:\/\/driveforges.com\/products\/hks-hipermax-r-coilovers-9k-front-10k-rear-2013-2021-scion-fr-s-subaru-brz-toyota-86-uhh3ln","provider":"Drive Forge","version":"1.0","type":"link"}
