Roll cage rules"
"3: SAFETY
3.1: Rollbar and Structure: Professionally made full roll cage required. A poorly built, improperly mounted, or badly engineered rollcage can keep you from racing: Don't show up with crap! At minimum, cage must include: Full front and rear hoop, appropriately braced to each other along the roofline; two drivers-side door bars (X-design is acceptable); appropriate main-hoop backstays with no bends, located as close to 45 degrees from horizontal as practical; one main-hoop diagonal; appropriate spreader plates and gussets; complete 360-degree welds at all joints. Each major load-bearing member must be formed from its own single, continuous tube. Shoulder-harness bars strongly encouraged, and virtually necessary for proper shoulder-harness mounting in some applications (the attachment point of all shoulder harnesses must be between zero and 15 degrees lower than the seat-entry point); dash bars very strongly encouraged.
3.1.1: Rollbar Tubing and Padding: Minimum tubing size for cars weighing under 3000 pounds as raced is 1.50" x .120" or 1.75" x .095". Cars weighing over 3000 pounds as raced must use a minimum tubing size of 1.75" x .120". Properly-bent, racecar-grade and -quality tubing is mandatory: no stretched or crushed bends allowed. DOM mild steel is very strongly recommended over ERW (seamed) tubing.
3.1.2: Don't understand any of the above? See where it states "professionally made." You shouldn't be doing this yourself.
3.1.3: All roll cage tubing must be padded with high density roll bar padding wherever a driver may contact the tube.
3.1.4: All attachment points on the vehicle must be selected and reinforced as necessary so that, in an accident, the cage will not punch through, tear, or grossly distort the attachment point. Spreader plates, backing panels, gussets, and/or other reinforcing elements are generally required to meet this goal. Cages mounted to rusty, thin, under-supported, or otherwise stupid attachment points will flunk tech immediately.
3.1.5: Waivers: Previously entered LeMons cars that don't meet the above specs must upgrade their equipment or apply for an individual grandfather waiver before showing up for the race. Be warned: Waivers aren't automatically granted.
3.2: Driver's Seat: Driver's seatback must reach above middle of helmet or higher. One-piece SFI- or FIA-rated competition seats very strongly encouraged. All seats must be very securely mounted to the floor or cage to avoid separation during a crash. All seatbacks must be securely attached to the seat base and braced or otherwise restrained against rearward failure.
3.3: Onboard Fire Extinguisher: Fully charged Purple K, Type 10B:C, or Type A:B:C extinguisher, 2.5 lbs or larger, must be located in easy reach of driver and secured via a proper, purpose-made, all-metal quick-release bracket. (In other words, just go to the damn hardware store and buy a good mount; don't use the cheap plastic thingy that came with the bottle"
Be careful, the safety rules will cost some money. And they do check for 360* welds. We take our welder to races and invariably help teams that don't meet the rules. If you have to cut a hole in the roof to get your weld complete, do it. Sometimes you can get by with less than 360* if you use gussets and the total weldment is equal or greater than 360*, but I wouldn't rely on that. Its a case by case by judge by inspector type of ruling. Safer to get the 360*.
By the way, these are not the crashfests that they were during the first couple of years. Be prepared for significant penalties if you have car to car contact today.
