The Roots of AST:

Piet later left KONI to start Aragosta Suspension, becoming a leader in motocross and GP racing. Building upon this success, Aragosta expanded their product range to include most vehicles and participated at World Rally championships, Kartcross and Touring car events, setting records in the Paris-Dakar Rally in both the T1 and T2 categories.

Eight years later, Piet formed HI TECH where he worked with INDY cars for nearly a decade. Piet was very active in INDY CAR chassis and suspension and worked alongside drivers including the world renown Emerson Fittipaldi.

After leaving HI TECH, Piet formed AST with Peter Smits of Smits Factory in 2000. Together, the duo combined their years of technical expertise to innovate and manufacture new suspension systems. AST made its name through unparalleled quality control and manufacturing flexibility, setting it apart from many others in the suspension industry.

2016 – Present: A New Era

MOTON SUSPENSION USA / AST SUSPENSION NA is formed and headquartered in Irvine, California, at the heart of the US automotive industry. The US team specializes in serving the North American market via sales, service and product support, working directly with the AST and Moton headquarters in Holland.

With respect to service centres, we have chosen two USA providers with comprehensive knowledge of AST and Moton products. These service centres have factory-trained suspension technicians on hand and maintain factory AST and Moton parts in stock. For west coast coverage, we have Performance Shock Inc. (Psi) located in Sonoma,CA and for the east coast we have RE Suspension in Morresville, NC. These two locations ensure strong product support for our professional and club racing clientele and minimize turnaround time for damper service and repair.

Both centres have been chosen to make sure our technical products are maintained in the most authentic way possible. Each service centre has their own direct line to Holland, which ensures each damper is serviced with factory genuine internals and processes, and cuts down communication time for service.

We look forward to working with you throughout the end of 2017 and into 2018 and stay tuned for more updates coming from our team.
