esr Posted March 18, 2012 Share Posted March 18, 2012 Can someone clirify the size of the tubing, seems to me that the rules state that cars over 3000lbs need to run 2 inch tubing. Talking to the local builders they tell me that 1 3/4 is all you need. Anyone knows for sure. Thanks Quote Link to comment Share on other sites More sharing options...

Anyone knows for sure. Thanks Better read the CCR again- it clearly states for cars weighing between 3,001-4000 pounds, 1.75 X 0.120 wall 4130, seamless alloy or DOM is required. ERW is NOT allowed (p. 61). Quote Link to comment Share on other sites More sharing options...

ERW is NOT allowed (p. 61). Actually, according to section 15.6.18 of the 2012.2 CCR, it says: For the purposes of determining roll bar tubing sizes, vehicle weight is as raced, but without fuel and driver. 2501-3000lbs 1.500" x 0.120" Seamless alloy (4130), Seamless mild steel.... 1.750" x 0.095" Seamless alloy (4130), Seamless mild steel.... 3001-4000lbs 1.750" x 0.120" Seamless alloy (4130), Seamless mild steel.... I just read that Palmettogasman's car came in at 3040# with a 185# driver...which means his car alone weighs 2855#. So if I'm understanding this correctly his cage would be legal if it was constructed with 1.500" x 0.120" 4130. So for those who have built cages already, what tubing size did you use, and do you have pictures to share? Quote Link to comment Share on other sites More sharing options...
Fixxxercask Posted April 26, 2012 Share Posted April 26, 2012 I just had mine done over the winter with the 1.75x.095 tubing. I noticed that in the rules. My car without fuel and driver is about 2850lbs. Quote Link to comment Share on other sites More sharing options...
National Staff Jeremy C. Posted April 26, 2012 National Staff Share Posted April 26, 2012 Went with 1.75x.120 for extra safety for my build! Quote Link to comment Share on other sites More sharing options...
scotts300 Posted May 1, 2012 Share Posted May 1, 2012 Went with 1.75x.120 for extra safety for my build! Hi Jeremy! When do you plan to debut your build at an event? All - how many feet of tubing do you estimate are used to build the cage? 40-50? Quote Link to comment Share on other sites More sharing options...

All - how many feet of tubing do you estimate are used to build the cage? 40-50? Shooting for end of this month! (Fingers crossed). I think we ordered 80' of tubing, but that was going to be more than enough! Quote Link to comment Share on other sites More sharing options...
Blackbird222 Posted August 2, 2012 Share Posted August 2, 2012 Jeremy's cage can be seen in the latest issue of SpeedNews - http://www.snmagcurrent.com/publication/?i=120245&p=58 Another view of "the office" - Moti @ Blackbird Fabworx Quote Link to comment Share on other sites More sharing options...
velocitymotorsports Posted August 8, 2012 Share Posted August 8, 2012 Cage looks good but it looks like the lower bar and upper support bar would be in the way of a quick exit. Ill get some pictures of the cages that hanksville hotrods did for our 350 i anyone is interested in seeing how its all tucked in. Good to see some spec build pics. Thanks guys and gals.

I'm assuming you're refferring to the A pillar support which may appear that way in some pics because of the angle, but in reality barely takes anything away from the window opening.
