Frequently Asked Questions


Brand: ST Suspensions
SKU: STS1820285802
UPC: 840134905365
The XTA plus 3 coilover kit gives your car maximum performance for the road and the tools you need for any challenge. From the factory, the XTA plus 3 coilover kit is equipped with KW dampers that are adjustable in high-speed 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, 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 aluminium unibal top mounts. Easy lowering adjustment: Like all ST coilovers the ride height adjustment is made via seamless thread on the galvanized strut housing. This even allows the ride height to be adjusted even when the kit is installed by adjustubg the spring perch higher or lower! NOTE: The lowering of each vehicle differs greatly with ST XTA plus 3 coilovers due to the type of construction. KW Engineering: Exclusive for ST suspension. 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.

Came based on a work buddies recommendation. I was late by 30 minutes, confused my appointment time. But, 10/10 would come back. Came for a Downpipe and midpipe install. Not only was the gentleman accommodating, He ran into some issues, staff helped me out and pointed me into the right direction and got me going! They got my business and wouldn’t go anywhere else again!

Absolutely love the customer service that you get with Speedzone Performance! All my questions are always answered in such a timely manner and this a big PLUS because I live out of Florida and for them to be on top of answering all my questions in such a way means a lot. Thank you all for the amazing customer service.

My favorite place to go for anything car related, they have anything you could imagine & more. The people who work here are the coolest and most helpful people I’ve yet to meet at a car shop. They also don’t try to force sales on you and they genuinely help you with what you’re looking for, 100/10 shop!
