Curious what everyone is running for cages. I was going to run 1-5/8 .083 wall Cmoly for NHRA SFI spec, but I'm not sure any of these other road race events or sanctioning bodies will pass this diameter/thickness. For open road race or autocross what do they require? I've read somewhere that 1-3/4 .120 moly is recommended. The tubing costs more, plus the die cost, but this would pass NHRA with no problem.
It seems easy enough to just put in the 1-3/4 but I'm a tight ass
and can save about $500 if I can just run the 1-5/8. Also if I do put in the 1-3/4 .120 wall I want to make sure that's the correct thickness. Please let me know what you guys have run into.
Thanks for your help,
Brett
