For those who demand the absolute best performance comes the ST XTA coilover. The full driving behaviour of your car can be adjusted using KW dampeAr technology along with an adjustable aluminum uniball top mount for fine-tuning of the camber and caster! ST XTA coilovers feature KW damping technology which allows the suspension to be made either stiffer or softer depending on the driving conditions. This damping adjustment is made on the upper end of the chromed piston rod allowing the setup to be changed almost instantly. If the rebound force is increased, the car will drive with even more track stability and further reduced bodyroll. If the rebound force is decreased, the car will feel more comfortable when on the move. For increased performance, the ST XTA features an aluminium adjustable topmount allowing the camber and caster to be adjusted depending on your driving needs or vehicle setup. Latest damping technology for maximum longevity Reduced system friction for effective damping adjustment Lowering within TüV-tested adjustment range of 0.8-1.6"F, 0.8-1.6"R Front and rear axle with thread adjustment Galvanized coilover struts with additional coating for an optimized corrosion protection Complete solution with adjustable spring plate, race spring system and bumpers with dust protection Aluminum adjustable uniball top mounts Scaled camber adjustment Externally adjustable damping 5 year limited warranty

ST Suspensions - German-Engineered Coil Overs at an Affordable Price.
ST Suspensions has partnered with KW Suspensions in Germany to offer an affordable German-engineered coilover kit. The ST coil overs are based on the entry-level KW Variant 1 but with zinc-plated shock bodies in place of the more expensive stainless steel. Each ST coilover has dampers perfectly tuned for the springs included with the kit. It's a matched shock and spring package with the added feature of adjustable ride height. This delivers a comfortable but sporty and controlled ride without being jarring or uncomfortable. The engineering and performance is unbeatable at this price! The ST coilover kit is packed with features found on more expensive fully-adjustable coil overs -

  • Pre-set fixed damping optimized for a blend of ride comfort and handling with less bodyroll
  • Zinc-plated steel strut/shock bodies
  • Composite-coated spring perches reduce noise and vibration
  • Individually height-adjustable
  • TUV approved lowering range and operation
  • Expert engineering and design for ease-of-use and long durability
    This is the ideal coil over kit for an enthusiast owner who does not plan on tracking or autocrossing the car and just wants a lower, more aggressive stance and better handling. ST has set the shock damping rates to be an excellent balance for a smooth yet taut ride, and to resist bodyroll motions for better handling. If you want a sportier ride and better handling than stock ST Coil Overs are an excellent choice.

    Front:0.8" to 1.6"

    After the success of ST's XTA line of coilovers, it's no wonder ST decided to take things a step further with their all-new XTA Plus 3 coilovers. These new coilovers take many of the great features of the XTA line and integrated them in a package with significantly more control, allowing you to individually adjust 3 dampening settings, including High-Speed Compression, Low-Speed Compression, and Rebound dampening. This makes dialing in your preferred tack settings a breeze and allows for fine-tuned adjustment to suit any track conditions and racing styles! As an added bonus, this means even major vehicle modifications (such as heavy roll cages, bushing changes, altered wheel loads) can be taken into account when adjusting your coilovers to help you further maintain similar optimal handling characteristics. Features: Latest damping technology for maximum longevity Reduced system friction for effective damping adjustment Individual lowering within the tested adjustment range Front and rear axle (when possible) with thread adjustment Galvanized coilover struts with additional coating for an optimized corrosion protection Complete solution with adjustable spring plate, race spring system, and bumpers with dust protection Aluminum adjustable uniball top mounts (when possible) Scaled camber adjustment (when possible) 3-way adjustable dampers: 18 clicks low-speed rebound damping 24 clicks low-speed compression damping 24 clicks high-speed compression damping Lowering Specifications: Front: 1.2-2.8" Rear: 1.2-2.0"
