Many drivers often overlook the inherent slack in their vehicle's factory subframe, particularly in models like the Honda Civic. This slack is a result of OEM engineers balancing performance with comfort and cost. For instance, the subframe mounting holes in the 11th Gen Civic have a 2mm gap that can lead to unwanted shifts, vibrations, and rattles during aggressive driving, which ultimately affects steering responsiveness.
At PRL Motorsports, we focus on enhancing performance, which is why we created the SRS Collar Kit. This innovative solution effectively addresses the slack issue by filling the 2mm gap around the subframe mounting bolts, ensuring a secure fit that minimizes any unnecessary movement. With this upgrade, you'll experience a noticeable reduction in vibrations, improved handling, and enhanced chassis rigidity—perfect for track days, autocross events, or just elevating your daily driving experience.
"After installing the PRL SRS collars, I noticed a huge difference in my Civic's handling. The steering feels much more precise, and the car feels more planted during turns. Highly recommend!" - Alex T.
"I was skeptical at first, but these collars really do make a difference. The vibrations are gone, and my car feels so much more responsive now." - Jamie R.
