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.

From the factory, the XTA plus 3 Coilover kit is equipped with KW dampers that are adjustable in high- and low-speed compression as well as adjustable rebound damping. With 24 clicks of adjustment for each, high speed and low-speed compression damping, and 18 clicks of rebound adjustment, your suspension knows no limits. It doesn't matter if you bolt in an aftermarket roll cage, weld in a cage, modification to PU bushings upgrade to spherical bushing or changed wheel loads - the XTA plus 3 coilover has what it takes to keep your car dialed! Of course, the XTA plus 3 also includes a parts approval certificate, race springs, and aluminum unibal top mounts. Like all ST coilovers, the lowering adjustment is made via a continuous thread on the galvanized strut. This even allows the lowering to be made even when the kit is installed by turning the spring plate higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XTA plus 3 coilovers due to the type of construction. The high-quality ST XTA plus 3 Coilover is based on the twin-tube damping principle of low friction combined with pressure-resistant damper housings. Manufactured directly at KW, a mono block guide and seal package reduces the friction of the damper as well as protecting it against corrosion and dirt. Each galvanized strut is sealed multiple times to ensure maximum longevity in ALL weather conditions.

For the driver that demands the best out of their vehicle. The Dinan Adjustable Coil-Over Suspension was bred in the race lab but refined on the street for maximum versatility. No matter the environment, the traction that is bestowed upon the vehicle from the improved suspension will inspire new found confidence when running at higher speeds. From the substantial reduction in body roll as well as reduction of dive under braking and squat under acceleration, Dinan guarantees you superior handling, performance, and comfort. Dinan's design retains the superb factory electronic shocks but swaps the springs to a more aggressive formula and implements threaded collars to allow the user to change the ride height. While a stiffer spring is typically associated with diminished ride quality Dinan has also swapped the progressive rate rear springs in favor of a much more predictable linear rate spring design. This allows for a more compliant feel while still being able to enjoy the benefits of a stiffer setup such as the reduction in body roll. The end result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allows the car to be lowered an incredibly low two inches in the front and 2-1/8 inches the rear. However, in order to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 1" in front and 1-18" in the rear is advised. For suspension connoisseurs or those that are just simply very particular suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops something no respectable race car is without. Due to the extensive lowering possible and the increased suspension travel, the installer must carefully evaluate tire clearance under all situations. Safety will be compromised if all precautions are not taken. Dinan is not responsible for any property damage or injury. Features: Threaded collars allow easy and precise front & rear vehicle height adjustments. Up to 2" of lowering in front and 2-1/8" of lowering in back are possible depending on tire clearance but with diminished ride quality. Dinan recommends a 1" drop in front and a 1-1/8" drop in the rear to maintain a civilized ride. Spring rates are 20% stiffer in front and 15% stiffer in the rear. Stock rear springs are progressive whereas the Dinan springs are linear. Helper springs are utilized in the front and rear to maintain proper suspension operation under droop conditions as well as accommodate the extensive travel of the stock shocks. Substantial reduction in body roll. Included suspension packers allow adjustment of bump-stop clearance to fine-tune handling and comfort. Dinan-spec progressive bump stops improve ride quality at lowered ride heights. Components are machined from 6061-T6 aluminum and black anodized for a sporty appearance as well as corrosion protection. Stock upper spring mounts are utilized for quiet operation.

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.

For the driver that demands the best out of their vehicle. The Dinan Adjustable Coil-Over Suspension was bred in the race lab but refined on the street for maximum versatility. No matter the environment, the traction that is awarded to the vehicle from the improved suspension will inspire newfound confidence when running at higher speeds. From the substantial reduction in body roll as well as reduction of dive under braking and squat under acceleration, Dinan guarantees you superior handling, performance, and comfort. Dinan's design retains the superb factory electronic shocks but swaps the springs to a more aggressive, performance-enhancing formula and implements threaded collars that allow the user to change the ride height themselves. While shorter, stiffer springs are commonplace in aftermarket suspensions and are a key element in reduction of body roll it is not a one-size-fits-all all approach. In the case of the G8x M3/M4 where the vehicle has a penchant for oversteer, stiffening the rear springs would exacerbate the problem of the rear losing traction before the front when the platform is pushed to the limit. Dinan instead has opted to soften the rear spring rate as well as switch from the factory progressive rate rear to a dual rate spring setup. The combination increases predictability and compliancy, and in turn, provides better rear grip/road holding for a vehicle that needs both. The result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allows the car to be lowered up to 1-1/8" in the front and 2-1/4" inches the rear. However, to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 3/4" (M4) or 7/8" (M3) in front and 3/4" in the rear is advised. For suspension connoisseurs, or those that are just simply very particular, suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops --- something no respectable race car is without.
