About Us

I/O Port Racing Supplies is located in Lafayette, California and was established in June of 1988. Specializing in safety equipment, I/O Port has grown from selling helmets and suits at local race events to having worldwide sales. We are constantly expanding our inventory to give you a more comprehensive source for racing goods. Recently we added the The JAWS Advanced Warning System now required by NASA for the 25-Hours of Thunderhill and Lucky Dog night endurance races. We also have added CTEK Battery Chargers, Red Line Brake Fluid, I/O Port Angled Window Nets, Radio and ChatterBox Cable Adapters and a ton of other equipment by major manufacturers such as ESS, Longacre, Kirkey, Safecraft and Simpson.

Our electronic catalog offers an in-depth overview of our goods. You may link to other sites on our Links page. You may download our sizing charts and other informational pages for future reference, but please remember, all information located on is for personal use only. All copyrights apply.

I/O Port manufactures video camera mounts, electronic devices, mirrors, window nets, cool suits, tow straps, steering wheel adaptors, seat brackets and seat-back braces. All of these items were invented to fill a need in the racing field. We are constantly looking for other needs to fill. If you have an idea that you think we would be interested in, please call or email to let us know.

I/O Port distributes quality racing equipment offered by the leading manufacturers. These manufacturers haven't been resting on their laurels - they've been working hard to bring you cooler and lighter driving suits, safer and better fitting seats, and lighter, cooler helmets, for instance. When we bring in new products, we test them at the track. You can rest assured that each product is of the highest quality and offered to you at the lowest price possible.

I/O Port offers Sponsorship only in the form of contingencies to race organizations. We are proud to help sponsor the NorCal NASA, the NorCal SCCA, Thunderhill Raceway Park and the Race Drivers Club. We have been known to provide contingency sponsorship to the SCCA's RDC Enduro and the local chapter of the Porsche Club of America (PCA) recently received items for door prizes for their annual autocross school. Because we feel that everyone should be treated equally, we discount prices universally...we do not sponsor individual drivers.

Many sanctioning bodies require the use of Head and Neck Restraints. I/O Port supports this step toward greater safety. Be sure the one that you choose is either FIA 8858-2010 or SFI-38.1 certified. The SFI certifies all these devices to a 70G load! I/O Port stocks the Head and Neck restraints from HANS and NecksGen. Simpson's R3, Hybrid, Hybrid Sport, Hybrid Pro, and the Hybrid-X devices are all SFI-certified. Both the HANS and the Hybrid are also certified for FIA and NASCAR. HANS with post anchors are FIA certified. Each device offers different comfort, ease-of-use and price points. If you would like any one of these devices, we now have stock in a variety of sizes. Which is the best Head and Neck restraint? The question is which one is the best for you. I/O Port gives you a choice! Call us to discuss your needs.
