ST Coilovers Kits
Looking for that perfect balance between comfort and performance, styling, and handling without sacrificing ride quality and comfort? Your search is over, from the company that brought you the KW V1, V2, and V3, we have the perfect ST Coilover to suit your Golf MK IV needs. Coilovers are the BEST suspension solution for aftermarket applications, simply because all of the parts are designed to compliment and function perfectly with each other. As opposed to playing the guessing game of buying springs and shocks separate.

ST Variant 1
When it comes to choosing the perfect coilover, don't be cheap, do it right the first time; choose ST height adjustable Variant 1 Coilover Kits. Fully threaded shock bodies will enable you to customize your ride height for that aggressive stance that you've always wanted, without sacrificing safety, functionality, or driving performance. Each application is expertly engineered, designed, and test under road and of course track conditions in Europe to guarantee it meets and exceeds the Highest Quality Standards of the German TÜV.

ST Variant 1 Advantages
  • Matched damper and springs rates
  • Corrosion resistant zinc plated threaded strut housing
  • All around height adjustability
  • Integrated elastromeric bump stop
  • Self centering dust boot for insured durability


Galvanized Steel
Coming from the makers of KW suspension systems the only main difference between the ST Variant 1 and KW Variant 1 is the steel they use. While KW uses Stainless Steel for their shock housing, ST uses Galvanized Steel. However, this does not mean a drop in quality, durability, or appearance. Although coilovers that use galvanized steel are more prone to corrosion due to environmental influences (i.e. mixture of salt water); those in the lower states: California, Texas, Florida, Nevada, etc. don't have to worry about corrosion. Those in the mid to upper States that snow still don't have much to worry about as long as they do not drive in heavy snow conditions upon where salt is used on roads. to further ensure those with doubt about Galvanized Steel, ST has corrosion resistant zinc plating on all of their threaded strut housings for further protection.

About Coilovers
A coilover suspension basically gives you a matched lowering spring and shock absorber combination with the added benefit of adjustable ride height and spring rates through a moveable spring perch or perches. Coilovers are to your car's advantage by reducing unsprung mass, increasing suspension travel, and allowing the car to be corner balanced.
