DemonZ Posted May 20, 2002 Share Posted May 20, 2002 I want to put in my own rollcage with one of those Harbor Freight mandrel benders. The main reason is I don't think there is a pre-fabed one that meets both SCCA and NHRA certs. Soooo... I was wondering if anyone has the rulebook specs for roll cages. SCCA or NHRA ok I am cheap too. I plan to use seamless tubing .083 .... Guys with experience putting cages in please chime in with your tips, and "would have should have's" TIA Quote Link to comment Share on other sites More sharing options...
Peternell Posted May 21, 2002 Share Posted May 21, 2002 Where in Washington are you?? I'm in the Tri-Cities. I could fax you the NHRA stuff, which unless I'm wrong (and it wouldn't be the first time) a cage passing NHRA spec's would also pass IHRA spec's.

DemonZ Posted May 23, 2002 Author Share Posted May 23, 2002 can anyone give me the regulations on SCCA rollcages? Quote Link to comment Share on other sites More sharing options...
Dp351zcar Posted May 23, 2002 Share Posted May 23, 2002 Try to contact Art Morrison Racing in Fife. They have plans of a 8pt roll bar that can be made into a cage with their kit. Memory fails me but I think I paid almost 200 for mine. It is nhra legal and a weld in. I know it's money but it would save a lot of time, and it is time that is hard to buy.

ZROSSA Posted May 23, 2002 Share Posted May 23, 2002 This may or may not be any help but...... Down here the road race rules are far more strict then the drag ones. I get the feeling that its the same in the states. I would build my cage to the SCCA rules. Hopefully someone will jump in and correct me if i am wrong.

pparaska Posted May 23, 2002 Share Posted May 23, 2002 Doesn't SCCA have a 0.120" min wall thickness for the main hoop (at least)? Quote Link to comment Share on other sites More sharing options...
74_5.0L_Z Posted May 23, 2002 Share Posted May 23, 2002 SCCA mandates 0.120 seamless 1.75" diameter(mild steel), or 0.083 alloy steel 2" diameter for the main hoop (2500 lb car). They also "suggest" using the same thickness on all supporting members. Quote Link to comment Share on other sites More sharing options...
katman Posted May 24, 2002 Share Posted May 24, 2002 Find an old copy of Z-Car Magazine, the issue where they described the cage for an ITS 240Z. It talks about the load paths and the SCCA requirements. A must read if you want to be safe. Since this keeps coming up, I got a copy I would gladly snail mail to somebody with a scanner if they wanted to put it up on the web somewhere where we could all read it. Unfortunately I'm worthless when it comes to PC's.... Quote Link to comment Share on other sites More sharing options...
DemonZ Posted May 24, 2002 Author Share Posted May 24, 2002 Dave at Art Morrison told me they didn't have a cage kit for the Z. They did have some for Honda's and Mistubishi's go figur... prices are double for chro-mo, and around half the weight: 140#, $260 vs. 95#, $520. Katman, I'd appreciate the piece on rollcage design. I'll shoot you an email. Quote Link to comment Share on other sites More sharing options...
