Koni / Hypercoil Sport Suspension for the Porsche® 928

I've had the Koni Reds with the 600/400 Hypercoil springs on my '85 for about 18 months. Incredible change on the track versus the old original shocks/springs, for the positive. Took the body roll right out, and is flat around corners. I expected the ride to be really harsh around town and have been surprised that its not nearly as bad as I was lead to believe it would be. Especially since as I age I notice it takes a lot less bumps to shake things loose! And this is with a basic Corbeau seat instead of the factory one. MGW-Fla

Just back from a 2500 km trip to the Nordschleife with my car. Ten laps on the circuit and all your suspension, brake and general performance upgrade parts worked really well. Thanks a lot for your effort! Its such a comfortable rocket to drive. Jan Frost U.

We haven't had time to install the sway bars but the suspension and shocks made a huge difference. They made us compete in B stock where we were the only ones on street rubber. I think they are scared, at least that's my take on it. My hat is off to all of you at 928 Motorsports for your products and willingness to help. Bruce B.

Easy to install, complete set, good handling. Kare B.

Thank you for all this information, I am delighted with the Koni suspension kit and I hope to make classic Le Mans this year. Christian R.

A complete set of 4 performance/racing springs, spring perch adapters, and ride-height adjustment sleeves for the Porsche® 928 (2 Front, 2 Rear)

Application: 1978-95 Porsche® 928

Kit Includes:

  • 2 Front Koni Red adjustable shock absorbers
  • 2 Rear Koni Red adjustable shock absorbers
  • 2 Front Hypercoil® brand performance racing springs
  • 2 Rear Hypercoil® brand performance racing springs
  • 2 Front Hard-anodized billet aluminum 928 Spring perch adapters
  • 2 Rear Hard-anodized billet aluminum 928 Spring perch adapters
  • 4 Hard-Anodized Ride Height Shock Collars installed
  • 1 Anodized aluminum ride height spanner wrench

Our spring perch adapters will convert your 928 from using hard-to-find metric springs to common 2.5" OD racing springs into your Porsche® 928 - and here are the benefits of doing this:
  • Lower unsprung weight
  • More clearance for larger tire/wheel combinations
  • Better selection of spring rates

Our spring kits accept all 2.5" OD springs. The 928 Motorsports Spring Adapter kit comes with one set of 4 premium-quality Hypercoil® springs with it - but in the future you can use any brand of 2.5" springs you can get anywhere, or come back to us for another set of Hypercoils!

Choose from any of these popular spring combinations for your 928:

... or let us talk to you about your particular spring, shock, and swaybar setup and the type of driving/racing you do and we will customize a set for you!

Easy Installation Our kits come with everything you need to do the complete installation yourself. Instructions included. No modifications are necessary to the car whatsoever. And, we are going to install the ride-height adjustment sleeves onto the Koni's for you!

Easy Adjustments Because our threaded sleeves are new and anodized for anti-corrosion and toughness, adjusting the ride height of your 928 will always be easy from now on with the special spanner wrench included in this kit!

Top Technology! 928 Motorsports is proud to be a Hypercoil® dealer. We selected Hypercoil® (proudly made in the USA) because Hypercoils are manufactured from the highest quality chrome silicone steel and high tensile chrome silicone steel available in the world. Hypercoils are designed to be as light as possible with maximum deflection and at the same time endure the stresses of the extreme conditions common to motor racing. Hypercoils will resist taking a "set" longer than most springs.

Extended Spring Perch Available For our customers looking to lower or raise their 928 more than normal, we offer an optional extended spring perch.

Testimonial of our Hypercoils at Spa: "I finally got around to testing the new suspension in Spa last week and boy what a difference! The car feels rock solid on the track as opposed to the swaying it did before. I'm very happy with my choice of springs and I'll recommend it to anyone who asks. Starting out in 19th position (At Spa) I had already passed 5 cars at the top of Raidillon. The straight line speed of the 928 was a lot higher than most of the others so the long straight Raidillon was ideal for overtaking them. The stability of the car with the new Hypercoils and the Pirellis is phenomenal, so even though I had never raced at Spa before, I did manage to run at the same pace as the other Porsches (except for a 911 RSR 3.0). I finished in 8th place in general and 3rd in my class after a 25 minute race so needless to say I was very satisfied. First race, first podium of the season." - Jerry Dowered, Belgium
