Q: One on One Spring Rate Support Included

We work directly with you to choose the right spring rates and setup for your car at no extra cost. Your suspension is not built until we have reviewed your use, goals, and confirmed the final spec with you. Prefer to keep it simple? Our default specs are carefully chosen for each chassis using real world testing, years of consultation data, and feedback from drivers just like you.

Q: Extensive Development for Each Application

We develop on real cars: measuring motion ratios, wheel rates, and tire behavior so the final product works outside the lab.

Q: Hand Built & QC’d in Fremont, CA

Assembled and quality-checked by enthusiasts for enthusiasts, not a mass-produced catalog product.

A great suspension set up for my VB WRX. Great customer service, solid products, and custom tuning makes this emerging company a stand out. Great value for what you get.

I ordered a set of Annex FastRoad coilovers for my AE86 and had an AutoX event coming up the same week they were supposed to arrive. I reached out to see if there was any way to get them a bit earlier, and shoutout to Kaz and the Annex team — they came through and got them shipped out ahead of schedule so I could have them on in time. As for the coilovers, the difference was immediate. Ride quality is way better — they smooth out rough roads really well, but still give great handling and feel super planted in the corners. Honestly, I’m really impressed with how they ride both on the street and at the limit. Definitely going to consider Annex again for future builds. Solid product and even better customer service.

Awesome group of people. I swung by because I was in the area getting some work done in a car and noticed annex suspension was around the corner. I heard about these guys from speed academy and decided to see if they had anything to look at. Will came out and ordered a tour of their production assembly where they piece their custom shocks together and Dyno test them. Super great experience. I even got to meet Grant, the owner, and they were really friendly. I'll probably be shopping here when I look to upgrade my suspension in the future

Annex Suspension Group is an all around EXCELLENT experience. Annex has some very cool products developed and tested in house, backed by amazing people, real world testing, and experience spanning from street, to road course, to circle track. I'll be using them as much as I can for my suspension needs and track setup questions.

After running my FM stage one shock and spring combo I was on the lookout for a new suspension for my NC miata. Purely used for the track I came across a local group Annex and decided to support there company. After many track days and really pushing the limits these coils are honestly the best. Grant and Doris are great people and there team work hard day in and day out to put the best product and I am really happy that I went this route. I am running there Fastpro CD. For the track these are zero to none. Reset my damping and it feels better than stock and the best part there quite! If you are tired of the same o brands and are waitting for the next best coilovers hands down Annex is the way to go. There tech in the suspension is refreshing and not to mention how easy it is to lower my car with out the wrench falling off. Also one of the best customer service for a coilover company I have ever dealt with.

Annex Coilovers hands down is one of the best products out there 🙌. Having a wide variety of choices out there in the market right now, Annex is by far my first choice. Being made and tested by actual enthusiasts within the automotive community the team over at Annex have spent countless hours developing and testing their coilovers targeting specific markets. I haven’t felt a better setup in their FRS and was blown away of how smooth the car felt. Im looking forward to the growth and future application list they will be coming out with knowing how much time and effort they’ve spent on the development and dynoing on current applications available and I’m sure you would be too! If you ever come across the team, feel free to ask questions about your application
