FAQsÂ
Frequently Asked Questions Unified Dirt Late Model Specs
Q. What is the purpose of these rules? A. The Unified Late Model Council identified several areas where products and industry knowledge should be applied to late model racing. Q. What is the timetable? A. All the specifications on the bulletin will be effective for the 2017 season. Starting with the first events. Q. What happens if we don’t have the item? A. Compliance is expected. Q. Where do I get all this stuff? Parts Suppliers, Chassis Builders, Online Suppliers and many vendors have already circulated product information. The builders and suppliers have knowledge of all the products included. Many have been on the market for years and are common in short track racing.
Seats:
Q. How do I know if my seat is compliant? A. The best resource for that answer is the seat manufacturer. They know the type and design of their products. They will also know if replacement or modification is required. Q. What is “full containment”? A. Again, the manufacturer of your seat will know this answer. Some manufacturers have kits that may be used to bring a seat into compliance. General description includes Design shall include comprehensive head surround, shoulder and torso support system, energy impact foam, and removable head foam. Q. Can I use the seat I have? A. The goal of this specification is enforce a full containment with comprehensive head surround, shoulder and torso support system, energy impact foam, and removable head foam head surround, upper body support and overall strength. The seat builders know exactly what will work. If applicable, upgrade kits and bolt on components may work with your base seat. The seat builders know the answer. Q. I am a really big guy…. Containment seats won’t work. What can I do? A. Several of the seat companies and safety companies offer an acceptable alternative to the left side head surround. The surround is supplemented with a net that attached to the seat and roll cage. Keep in mind this is left side only and needs to be installed correctly. A “latch” version of the surround has also been developed.
Fuel, Fuel Cells, Fuel Systems: Q. What is the Fuel Cell requirement? A. There is a huge difference in fuel cell construction. The FT3 specification is the industry-accepted minimum. Your chassis builder or parts supplier will know if the cell is compliant. Q. Can I tell the cell is compliant by looking at it? A. There are some easy references; the easiest is the stamping near the manufacturers name. The fuel fill plate, pick-up and return will all be on the top and the container will be filled with foam. Q. Where do I get one if mine is not and what should a new cell cost? A. Every Chassis builder or parts supplier including the online companies offer a dirt late model FT3 approved cell. Q. Can I make my current cell compliant? A. Most likely no. You will need to replace a non-compliant cell. Your parts supplier can help you with that… as important as the fuel cell is…. Holding gallons of a highly flammable fluid… is this the right place to not get the best?? Q. What are the straps? A. Your chassis builder most likely has these installed. If they are not in place they will have an add-on kit to secure the cell to the chassis.
Electrical Systems, Batteries, Electrical Accessories:
Q. What about the battery? A. Make sure your battery is securely mounted by brackets. Also make sure the posts are covered to prevent any thing from crossing the posts and creating a spark. You do not want your battery flopping around or held by a bungee. Q. Shut Off? What is that for? A. First, it’s a great way to shut the electrical system down on your car but more importantly it allows track safety to deaden the electrical system to prevent sparking, arching or engine run on. There are several options available including marine shut offs.
Wheel, Wheel Discs, Wheel Spacers:
Q. Why? A. There are incidences of wheel covers coming off and flying into spectator areas. Other than maybe saying, “where did my wheel cover go?” a driver seldom sees the result of the flying wheel cover. Replacing the 3 Zeus fasteners with bolts will be easy with kits that are now being produced. You can still use the same ring and cover. Kits are available from many of the usual vendors now.
Personal Safety Equipment: Q. Gloves A. The science is clear. The device has proven its value over and over. It doesn’t matter how fast… or type of car, size of driver, type of seat. Another great Christmas gift! There are several options of approved devices to accommodate your situation.
Fire Suppression
Q. This is expensive and complicated? A. Yes, this system requires a driver’s investment and is something we have gone too long without. There are several approved systems available and we encourage you to shop for the one that meets your car and position. Several companies have a kit available specifically for DIRT Late Models meeting these specifications. Thank you for your support of dirt late model racing. The true benefactors of all these specifications are the participants and their families.
