Hector Morales Posted May 11, 2023 Posted May 11, 2023 Hi. I am planning to add a 4 point rollcage to my weekend trackday car. Last year I participated into a couple HPDE and day tracks events, by that time, the car had all seats and OEM seat belt. This year I installed a race seat and a 5 point race harness and I am planning to add a 4 point bolt-on rollcage. (half cage). My questions are>>>. to run in HPDE/track days/Solo drive with a Race seat + 5 point harness + 4 points rollcage, 1. Do I need to use a HANS device? 2. If I do not install a rollcage, just using a race seat + 5 point harness, Do I need a HANS device? all your answers will be highly appreciated Quote

Sorry you didn’t get a response last year. In case you’re still wondering (or for folks that are reading this and might be in a similar scenario): The addition of safety equipment (harness) means the driver/car needs to comply with the technical requirements of Section 15 per Sections 11.3.2 and 11.4 of the CCR. In particular, checkout Section 15.5 regarding Driver Restraint System. For convenience: NASA Club Codes and Regulations (CCR 2024.0 Edition) Though you’re not racing in HPDE, from a pragmatic standpoint, you might want to look into a head/neck restraint if you’re running 4-5 point harness in lieu of regular seat belts. Consider that in the event of a high speed collision, though the harness will hold your shoulders/body in place, your head will still be traveling with the same velocity until your neck stops its motion. Talk about whiplash or literal breakneck speed! Quote
