Sitting above the standard Monotube coilover in spring rate and damper calibration, the HRSRSS37827-1 is engineered for drivers who regularly attend track days, HPDE events, or sprint races while retaining street drivability. The upside-down front strut design provides superior transverse stiffness and precise wheel guidance under hard cornering loads. Height adjustment of 30 to 70 mm at the front and 30 to 60 mm at the rear is achieved via a robust trapezoidal thread collar, and a TUV parts approval certificate is included for road-legal use where applicable. Every unit is designed, developed, and manufactured in-house by H\u0026amp;R Spezialfedern in Lennestadt, Germany using motorsport-grade materials.\u003c\/p\u003e\n\n\u003ch4\u003eKey

H\u0026amp;R\u003c\/h4\u003e\n\u003cp\u003eH\u0026amp;R Spezialfedern GmbH and Co KG has been developing and producing performance suspension components from its facility in Lennestadt, Germany since 1980. Beginning with motorsport spring technology and expanding into coilovers, wheel spacers, and stabilizers, H\u0026amp;R now offers suspension solutions for over 2,000 vehicle types. The RSS Clubsport coilover line represents the top tier of H\u0026amp;R's road and track-day product range, incorporating the same monotube gas-pressure technology and upside-down strut design found in professional racing applications.\u003c\/p\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\u003cstrong\u003eWhat Porsche models does the HRSRSS37827-1 fit?\u003c\/strong\u003e\n\u003cp\u003eThe HRSRSS37827-1 fits the Porsche 924 (1983 to 1988), 944 (1983 to 1991), 944 Cabriolet (1989 to 1991), 968 (1992 to 1995), and 968 Cabriolet (1992 to 1995). All models must have an aluminum rear axle; the kit is not compatible with the steel rear axle variant.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat is the difference between the H\u0026amp;R RSS and the H\u0026amp;R Monotube coilover for the Porsche 944?\u003c\/strong\u003e\n\u003cp\u003eThe RSS Clubsport coilover uses significantly higher spring rates and adjusted damper calibration compared to the standard H\u0026amp;R Monotube coilover. The RSS is positioned between the standard Monotube road coilover and a full H\u0026amp;R race suspension, making it the correct choice for drivers who regularly track their 944 but still drive it on the street.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the HRSRSS37827-1 have a TUV approval for street use?\u003c\/strong\u003e\n\u003cp\u003eYes. A TUV parts approval certificate is included with the HRSRSS37827-1 kit, making it road-legal in Germany and many other European markets. For use in the United States, no federal law requires TUV certification for aftermarket suspension, but the certificate demonstrates that the product meets stringent independent safety and engineering standards.\u003c\/p\u003e\n\n\u003cstrong\u003eHow much does the H\u0026amp;R RSS coilover lower the Porsche 944?\u003c\/strong\u003e\n\u003cp\u003eThe HRSRSS37827-1 provides a front lowering range of 30 to 70 mm and a rear lowering range of 30 to 60 mm. Exact ride height within these ranges is set by rotating the trapezoidal thread adjustment collar using the included hook wrench. H\u0026amp;R recommends consulting the TUV certificate for the approved adjustment range for each model.\u003c\/p\u003e\n\n\u003cstrong\u003eCan the HRSRSS37827-1 be installed on a Porsche 944 with a steel rear axle?\u003c\/strong\u003e\n\u003cp\u003eNo. The HRSRSS37827-1 kit requires an aluminum rear axle. Before purchasing, verify whether your 944 has the aluminum or steel rear axle by inspecting the axle carrier material. H\u0026amp;R's installation instructions provide a visual guide for this check. Installation on a steel rear axle is not possible and the product should not be purchased for that application.\u003c\/p\u003e\n\n\u003cstrong\u003eDoes the H\u0026amp;R RSS coilover fit the Porsche 924 as well as the 944?\u003c\/strong\u003e\n\u003cp\u003eYes. The HRSRSS37827-1 fits the 1983 to 1988 Porsche 924 as well as the 944 and 968, provided the vehicle has the aluminum rear axle and the 18 mm Porsche-type front strut bracket clamp. The 924 and 944 share the same transaxle platform architecture, which allows this single coilover kit to cover the full range.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat type of damper does the H\u0026amp;R RSS coilover use?\u003c\/strong\u003e\n\u003cp\u003eThe HRSRSS37827-1 uses high-quality single-tube gas pressure monotube dampers on both the front and rear axles. The monotube design provides more consistent damping response under high-heat conditions compared to a twin-tube damper, which makes it well-suited for track-day use where brake and suspension temperatures are elevated.\u003c\/p\u003e\n\n\u003cstrong\u003eIs a wheel alignment required after installing the HRSRSS37827-1?\u003c\/strong\u003e\n\u003cp\u003eYes. H\u0026amp;R's installation instructions explicitly require that wheel alignment, headlight aim, and brake proportioning be checked and adjusted to factory specifications after fitment. Any change in ride height on a transaxle Porsche affects camber, caster, and toe settings, so a professional four-wheel alignment on a computerized rack is mandatory before returning the vehicle to normal driving.\u003c\/p\u003e\n\n\u003cstrong\u003eWhat spring rate does the H\u0026amp;R RSS coilover use on the Porsche 944?\u003c\/strong\u003e\n\u003cp\u003eH\u0026amp;R does not publish specific spring rates for the HRSRSS37827-1 in their public consumer documentation, but the RSS Clubsport specification uses substantially higher spring rates than the standard H\u0026amp;R Monotube coilover, which is designed for a stiffer, more track-focused setup. For exact spring rate data, contact H\u0026amp;R directly or consult the TUV certificate documentation included with the kit.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eBefore beginning, confirm your vehicle has an aluminum rear axle and the 18 mm Porsche-type front clamp bracket. Do not install on steel rear axle applications.\u003c\/li\u003e\n\u003cli\u003eSafely lift and support the vehicle on jack stands at all four corners.\u003c\/li\u003e\n\u003cli\u003eBegin at the front axle. Remove the front wheels, then disconnect the front strut assembly from the hub carrier and upper strut tower mount.\u003c\/li\u003e\n\u003cli\u003eNote: the OEM front bump stop must not be reused. The HRSRSS37827-1 uses an internal bump stop built into the front strut tube.\u003c\/li\u003e\n\u003cli\u003eInstall the new front coilover strut assemblies, referencing the H\u0026amp;R adjustment dimension guide. Set initial ride height from the center of the upper mounting bolt to the spring seat per H\u0026amp;R's measurement table.\u003c\/li\u003e\n\u003cli\u003eMove to the rear axle. The torsion bars must be removed before the rear coilovers can be installed. This requires dismantling the rear axle carrier with trailing arms, disconnecting brake lines and cables, loosening drive shafts, and removing the exhaust. Budget approximately five hours for torsion bar removal per the Porsche workshop manual.\u003c\/li\u003e\n\u003cli\u003eInstall the rear coilover dampers noting that the mounting eyes are offset-welded. Verify clearance to the axle carrier and body before torquing to specification.\u003c\/li\u003e\n\u003cli\u003eReinstall all components in reverse order, torquing all fasteners to Porsche factory specifications.\u003c\/li\u003e\n\u003cli\u003eReinstall wheels and lower the vehicle to the ground.\u003c\/li\u003e\n\u003cli\u003ePerform a professional four-wheel alignment and headlight adjustment before driving.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead and phthalates, which are known to the State of California to cause cancer and reproductive harm.
