CREATIVE SPRIDGETS is an interactive design workshop for performance and reliability modifications requiring ordinary shop tools, commonly available auto parts, and where necessary, CNC-machined core components. Our goal is to provide Spridget owners with the least-expensive route to desirable upgrades.
We provide shop-tested, on-line instructions for each project with photos and videos. However, if you can improve on any aspect of an installation, please contact us and we will post your comments and photos or videos of your refinements. Many have already done so.
We particularly appreciate learning about cheaper sources for a project's parts list to maximize savings for Spridget owners.
