9.99 1/4-mile (6.39 1/8-mile)/ 135 mph or quicker:
-Roll cage is required on all vehicles at 9.99 and quicker or any vehicle running 135 mph or faster (regardless of e.t.). The roll cage must be constructed of a minimum o.d. mild steel or chrome moly tubing (moly can be a smaller o.d and is lighter but more expensive), see diagram below for specs. Roll cage must be padded anywhere the driver's helmet may contact it while in the driving position, see diagram below for specs. Roll cage must also be certified by NHRA every 3 years and have a serialized sticker affixed prior to participation. This style of cage is good til 8.50 1/4-mile times, then a funny car style cage is required.
See diagram below.
-Window net required (can be ribbon or mesh, no altering allowed unless done by manufacturer. 2009 NHRA rule book states mesh nets carry a manufacturer date and a 2 year expiration/re-cert, while ribbon are good forever. Check with your local track or division).

done by car designation (dragster, door car, etc). A physical, 2 NHRA licensed drivers to witness/sign your forms and a minimum of 6 runs are required. For NHRA license form click here: www.nhra.com/contacts/forms/licenseapp.pdf

-Battery cutoff (regardless or whether battery is still up front or relocated to rear of vehicle). The cutoff switch must shut down everything electrical when off; see here for pictures and a wiring diagram: http://www.ls1tech.com/forums/drag-r...ct-switch.html
-A full-face helmet is required with a minimum Snell K98 or M2000/SA2000 rating. Helmets last 12 years from their rating date (example a Snell 2005 would be good until 1/2017). Shield is permitted, and modifications to helmet or shield are prohibited. This rule posting is as it applies to cars like ours (closed body type). For open cars a different helmet ruling is required.
