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 damper technology along with an adjustable aluminium uniball top mount for fine-tuning of the camber and caster!

Performance driving in mind
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.

Easy lowering adjustment
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 coilovers due to the type of construction. For example, older vehicles such as the Honda Civic (EJ9) can be lowered between 40-75mm with ST XTA coilovers, while newer models such as the Audi S3 (8P) can be lowered between 10-40mm due to being much lower from the factory.

KW Engineering: Exclusive for ST suspension
The high-quality ST XTA 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.

- 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, spring system and bumpers with dust protection
- Aluminium adjustable uniball top mounts (when possible)
- Scaled camber adjustment, when possible
- Externally adjustable damping

Choo Choo Desk
Color: White, Size: 40inch without Power Outlet
When looking for a desk; you're considering size and practicality for your purchase. Additionally, you're hoping the assembly of the desk will not require a brain surgeon to apply assembly. As this is my second Choo Choo Desk purchase; both the price, size, practicality and assembly are top notch. My wife uses one as her craft/sewing platform and the other as her computer desk. In placing both side by side, she can negotiate from one to the other with little to no effort and as it offers enough room on each platform with drawers for her notions, notebooks and patterns; She is quite content with her Choo Choo Desk(s) set up. For those searching for a great desk, this Choo Choo set is ideal for minimum sized areas. One has a power bar with A/C and USB ports while the other is a simple desk corner to corner.

Good quality desk for the money
Color: White, Size: 40inch without Power Outlet
Overall this is nice little desk, cute, sturdy, and relatively easy to put together by myself. I took one star off because the bottoms of the desk drawers was missing. I contacted the seller and initially got a pretty quick response that the manufacturer would send replacement pieces and provide the shipping tracking information from the warehouse as soon as they had it. Then a few weeks went by without any word and I couldn't seem to contact anyone again (every link came up broken) so I thought I was essentially ghosted. But then they did contact me with the tracking information and eventually sent the replacement drawer flats. So it took almost two months to resolve but I did get the missing pieces and overall I'm pretty happy with this desk as it was exactly what I wanted for my small home office.
