H&R RSS48225-1 Club Sport Coilover Kit for Audi A3 2.0T FronTrak

H&R RSS48225-1 RSS Club Sport Coilovers are designed for the committed motorsport enthusiast who is willing to relinquish some ride comfort in return for ultimate handling performance. Featureing a fully-threaded shock body, H&R Clubsport Coilovers allow you to precisely dial in height adjustment to achieve optimum weight transfer. The firmest coil-over in the H&R street line, the RSS is the choice for weekend track and club sport events. All H&R products are 100% made in Germany and exceed ISO quality assurance standards.

H&R RSS48225-1 Coilover Vehicle Fitment:
This H&R Coilover kit is designed to fit the following vehicles.

H&R RSS48225-1 Suspension Height:
H&R RSS Club Sport Coilover kits allow for height adjustability. This allows the vehicle to be set to a ride height of your exact preference or to be set up for the best handling possible. Lowering height may vary on vehicles optionally equipped with factory sport suspensions or different engine configurations.

H&R Coilover Dampers:
H&R RSS Coilover kits have plated steel shock bodies to provide corrosion protection while allowing heat to dissipate faster than a stainless steel body. Mono-tube gas shocks are used to better control damping and provide stable damping characteristics in all situations. Mono-tube shocks are lighter than comparable twin-tube shocks to minimize unsprung weight. H&R damper bodies are a true threaded shock body for better heat dissipation than suspension kits utilizing damper inserts in a threaded housing.

Advantages of Mono-tube gas shocks:

• Stable damping characteristics are possible due to the larger oil capacity and improved heat dissipation.
• The larger piston valve creates a wider area to receive pressure and allow fine damping control.
• Oil and gas are completely separated, preventing aeration and cavitation.
• Oil radiates heat through direct contact with the threaded shock body.
• Unsprung weight is minimized.

H&R Coilover Springs:
H&R RSS Coilovers use linear rate 60mm O/D main springs crafted from a special (hf) 54SiCr6 spring steel to ensure premium quality and performance. The springs are also shot-peened which increases their life by over 200%. H&R 60mm Race Springs are a linear rate spring which provides consistent and predictable feedback through the entire range of suspension travel.

Advantages of 60mm Race springs:

• Standardized format allows for easily changing springs.
• Linear rates ensure predictable handling through the full range of travel.

H&R RSS coilover kits use secondary helper springs to keep the main spring tight between the perches when the suspension is at full droop. They "help" keep the main spring snug, if you will. A helper spring is two to four inches long uncompressed and has a very soft rate of about 25 lbs/in, just strong enough to push the main spring against the perch.

H&R Coilover Install:
Installation of H&R RSS Coilovers typically takes 4-6 hours. Basic hand tools and a spring compressor are necessary for installation. Please observe all safety precautions and follow proper installation guidelines while working on your vehicle. Additional suspension components may be needed in some applications, depending upon the make, model, engine and chassis of the vehicle. We typically recommend setting coilovers for a half inch gap between the top of the tire and the top of the fender lip for a good compromise between looks, performance and comfort. The optimal ride height for performance may be different than the optimal ride height for comfort. The optimal ride height for looks is up to the owners preference. Achtuning recommends waiting 1 week after install for the suspension to "settle" before alignment.

H&R Coilover Warranty:
H&R provides a lifetime warranty to the original purchaser.
