Recommended Posts

Hello! I've been using a 2005 Mustang Gt for Pro-Am drifting for about a year now and I would like to do road racing! My car does pass all tech specifications of the American Iron rule book other than the cage design being a little different. Formula Drifts rule book calls for a cage built with 1.5x.095 tube size for cars 3500 pounds and lighter. Mine being around the 3400 mark, would it be able to run still with this style cage? I've sent a few emails out and I'm awaiting responses, I also wanted to hear some public opinion as well.

From a few post down.

 

 

https://www.nasaproracing.com/rules lists the general rules at the top including CCR’s (Club Codes and Regulations), then has info for time trials, and then for the individual other series. For example, if you were going to run ST4, then you would check out the main CCRs at https://nasa-assets.s3.amazonaws.com/do ... 2017.8.pdf and also the Super Touring rules. Section 15.6 of https://nasa-assets.s3.amazonaws.com/do ... 2017.8.pdf has info on roll cages, and 15.6.18 has size info below, so if your car is 2501-3000 lbs (without fuel or driver), then 1.500x0.095 sounds like it wouldn’t be enough for wheel to wheel racing, but I believe that it would be fine for running thru HPDE and also Time Trials, but just not for wheel to wheel racing. - Jim

 

15.6.18 Roll Cage Tubing Sizes

For the purposes of determining roll bar tubing sizes, vehicle weight is as raced, but without fuel and driver. Note: There is an allowance of minus 0.010 inches on all tubing thicknesses. Minimum tubing size for the roll cage is:

 

1501 - 2500 lbs

1.500” x 0.095” Seamless Alloy (4130), Seamless mild steel (CDS Mechanical), DOM, or Docol R8 (only)

1.500” x 0.120” ERW* (No issuance of log books for cars with ERW cages) *Note- Specifications listed only for

reference for inspection of grandfathered vehicles.

 

2501 - 3000 lbs

1.500” x 0.120” Seamless Alloy (4130), Seamless mild steel (CDS Mechanical), DOM, or Docol R8 (only)

1.750” x 0.095” Seamless Alloy (4130), Seamless mild steel (CDS Mechanical), DOM, or Docol R8 (only)

1.750” x 0.120” ERW* (No issuance of log books for cars with ERW cages) *Note- Specifications listed only for

Guess he didn't like the answer the first time so he was hoping for a different answer this time??? LOL (but having to upsize the cage a 1/4in does suck!)
