Front Lowering -1.3"

Enhance the look of your BMW E21 320i 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.

We recommend installing Bilstein Sport shocks with these lowering springs.

This item fits the following BMWs:
1978-1983 E21 BMW 320i 323i

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.
