Custom designs are our specialty and we welcome new product ideas.

Engineering Services:

DSE is a custom engineering one-stop shop. From electronic hardware design to PC software, mechanical design and production, to everything in between. Contact us for professional results - we will work with you to make sure you get exactly what you are looking for. 

Automotive Aftermarket: 

Using motorsport inspired materials and design processes DSE is able to bring the automotive aftermarket closer to IndyCar, USC, F1, and NASCAR. Many OEM and aftermarket parts would not live up to the standards of professional motorsport. Our goal is to provide products that improve the strength, weight, function, fit, quality, and appearance of the OEM or aftermarket part using design techniques and materials that have been race proven. We will not produce something that does not significantly improve upon the original design. Our attention to detail and continued passion for motorsport and automotive performance means you'll get a high quality product at a reasonable cost.
