Simple Suspension Solutions
Engineered for drivers who demand control, durability, and precision handling—every lap, every time.
Who We Are
Built by Enthusiasts. Tested on the Track. Trusted on the Street.
At S3 Suspension, we’re more than a brand—we're a team of passionate enthusiasts who have grown up immersed in the Southern California racing and tuning scene. Based in Fullerton, California, our mission is to engineer reliable, high-performing suspension systems that deliver results both on and off the track.
Every product is developed, tested, and assembled in-house at our local facility. From Buttonwillow and Willow Springs to Chuckwalla Raceway, our coilovers are pushed to the limit under real track conditions. We also test on local roads and highways to ensure each system offers both performance and daily comfort.
Driven by precision and purpose, we’re proud to deliver suspension solutions that stand up to the demands of real drivers—every lap, every time.
"A competitive driver can't just slap on the most expensive parts to win. They need products that are specifically engineered to perform."
At S3 Suspension, we recognized a growing trend in the automotive world—where power figures often take priority, and suspension choices are based on hype rather than engineering. That’s why we set out to do things differently.
The Most Vital Aspect of Performance: Suspension
The most crucial component of any track or race car isn't just horsepower—it's the suspension.
A properly tuned suspension setup is what allows a vehicle to corner with confidence, maintain high-speed stability, and respond predictably across changing surfaces. Without it, even the most powerful build will fall short.
When suspension is poorly designed or improperly tuned, it shows. Excessive bounce, bottoming out, and vague feedback all lead to unpredictable handling and slower lap times.
Why We Started S3
S3 Suspension was born from decades of real track experience, working with countless platforms, suspension types, and tuning setups. Our team collaborated with local racers in a tight-knit Southern California community, helping them dial in their suspensions to find every bit of performance on and off the track.
Through those years, we saw a clear gap:
Not every enthusiast can afford a $5,000+ suspension setup, but everyone deserves a system that performs.
That’s why we created Simple Suspension Solutions (S3)—to deliver affordable, purpose-built coilover systems engineered for the weekend track warrior, the canyon runner, and the everyday driver who demands more from their car.
Our goal is simple- to provide competitively tuned, vehicle-specific suspension systems that make high-performance handling accessible—without compromising quality or performance.
