Team Associated RC28R Center Shock Spring Test: Soft vs Medium vs Firm—More Grip or Harder to Drive?

Team Associated RC28R Center Shock Spring Test: Soft vs Medium vs Firm With Lap Data Team Associated RC28R center shock spring tuning for 1/28 scale racers. A special thank you to Silver Horse RC for sponsoring the channel and providing the batteries used during our RC28R testing. Check them out at [www.silverhorserc.com](http://www.silverhorserc.com). In this video, we test the Team Associated RC28R Factory Team Center Shock Spring Set at IAM-RC Hobby Shop in Manassas, Virginia. We compare the soft, medium, and firm center shock springs to see how each setup changes rear traction, weight transfer, on-power steering, off-power steering, stability, rotation, and overall driver confidence. The RC28R comes with the medium spring from the kit, but for this test we started with the soft spring, then moved to medium, and finished with the firm spring. Each driver ran the car, gave immediate feedback, and we compared the feel of each setup on track. The soft spring gave the car a lot of movement and strong corner entry, but it also felt bouncy, twitchy, and harder to drive consistently. The medium spring settled the car down and felt more neutral. The firm spring surprised us the most, giving the car a flatter, more planted feel with better on-power steering and more confidence through sections like the lollipop and corner exit. As always, the goal is not to tell every racer which spring is “best.” Track grip, driving style, tires, oil, layout, and overall setup all matter. Instead, we test one change at a time, collect lap data, and share real driver feedback so you have something useful to consider in your own tuning. In the next video, we bring in up-and-coming driver Isaiah Meredith, return the car to a baseline setup, and use what we learned throughout the RC28R testing series to tune the car based on his feedback.
