Answers to Your Top Questions

StoneBuilt Racing is a home-based business, so we're often working on cars and at the track. For the fastest response, please email us at adam@stonebuiltracing.com.

We ship orders as quickly as possible. Please note that any custom work, such as race prep or custom sprockets, will extend the shipping time. Larger items like seats and axles are considered long lead-time items and can take 2–4 weeks. If you have a time-sensitive order, please reach out to us at the email above.

To ensure our parts work for your build, please provide us with the most accurate information possible about your car. If your build details are not accurate, the parts may not perform as expected.

StoneBuilt Racing is a passion project for me. I have a full-time job and a family, but I'm dedicated to providing the best parts and service I can. I have personally developed clutch kits for 170cc, 204cc, and 232cc built motors, and I stand by their performance. While I'm not available 24/7 like a large corporation, I will always do my best to help, especially if you have an upcoming race. In the past, I've even shipped customers parts from my own collection to ensure they made it to their event.
