Springs are the easiest and most cost effective way to improve your handling, get a more aggressive rake, and give your vehicle a more attractive stance. We do recommend replacing your shocks and struts at the same time with either Bilstein or Koni dampers.
Enhance the look of your BMW E85 Z4 M Roadster with a reduced fender well gap. H&R Sport Springs lower the vehicle center of gravity and reduce body roll for better handling. The progressive spring rate design provides superb ride quality and comfort. A lower wind resistance signature will make the vehicle more streamlined and improve gas mileage. If you are only looking to improve one part of your vehicle’s suspension, you cannot go wrong with installing Sport Springs. Fun to drive, H&R Sport Springs are the number one upgrade for your vehicle.

This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per each.
