RCD - Race Car Dynamics has evolved from over 40 years of manufacturing experience by the Asbury family. In business since 2000, RCD manufactures and distributes 100% American-Made products, and has established a reputation for excellence in the marketplace.
Teamwork has been the key to continued success throughout the years. Always in search of new concepts, the RCD team has the vision to design, develop and produce cutting edge products. The RCD creed is simple: Quality Products, Superior Design, Made in the USA.
A new generation now controls RCD. The corporate name has changed to Race Car Dynamics of Arizona, Inc. While firmly entrenched in Southern California for years, RCD saw an opportunity for a more favorable business environment in Arizona that allowed further expansion of business and an opportunity to capitalize on growth in several segments of the suspension industry. The new RCD location has two large buildings, housing executive offices, research and development, manufacturing and warehousing. Accesspeed is proud to offer RCD products to our customers. With our lowest price match guarantee, you will always find the best combination of price and selection at Accesspeed.

Do lowering springs improve performance?
Assuming the springs are good quality, yes. Typically, the lowering springs have higher spring rates, which improves weight transfer, responsiveness and acceleration.
Do lowering springs hurt ride quality?
No. Most street and sport lowering springs are designed to ride as close to factory as possible, maintaining similar suspension travel, and minimal (up to 15% higher) spring rates. Additionally, most progressive rate street and sport springs keep the factory spring rates for the first 25-20% of spring travel, which preserves that factory ride quality.
Can I improve my spring performance without lowering my vehicle?
Yes. Several brands offer “OE Ride Height” performance springs that provide the improved handling characteristics, without lowering the vehicle stance.
Do you need an alignment after replacing springs?
Yes. You will need an alignment after replacing springs, whether lowering, stock or lifting.
