For all 914
 
Gives quick and easy infinite ride height adjustment to Bilstein or Koni rear shocks.
Ideal for proper corner balancing setup.
Progressive or Tender/Main spring combinations can be used resulting in a modern comfortable yet very well handling ride.
Square threaded design is stronger than traditional threads and actually locks the spring perch in place 
under load, this is backed up by a nylon tipped set screw for extra security.
Utilizes lightweight 2.25" ID springs to reduce overall weight compared to heavier stock 914 rear springs.  Spring perch adapters are optional for use with 2.5" ID springs.
All components are anodized for great durability and appearance.
Complete kit for both sides.  Springs and shocks sold separately.
Available with new Bilstein "Sport" shocks and springs.
