Hi guys,

I was wondering for drag racing what do the rules say about what types of roll cages are required? I think it is when your car starts to be faster then 12.0 seconds (not sure) in the 1/4 mile, then you are required to have a roll cage. But is there a specific type of roll cage required? or will a Cusco or Do-Luck bolt in roll cage work fine?

Also Does anyone here use the Cusco or Do-Luck cages on their FD (or any other gen)? I've seen pics of them on AE92s and Skylines, but I would like to see some on RX-7s, especially the drivers side. I know that Rutt, the moderator in Far East had a Safety21 roll cage which is the same as the Cusco or Do-Luck, and it pretty much saved his life when he got into an accident. So what are all of your opinions on the Safety21, Cusco and Do-Luck style cages?

Thanks

 

I'm not a drag racer, so I'm not familar with the rules. However, I did some digging and here's a quick rundown Hotrod did on the rules you need to comply with to be NHRA legal, but the exact rules must be gotten from NHRA.

I have no idea what the specs are on any of these rollcages you posted, so I'd start digging for info on those cages.

OPPS!!!

I forgot all about this thread...

Thanks for the link Silkworm, I tried a search on yahoo.com but I didn't come up with any good results.

I wanted to get into some road racing on some of the local courses like Thunder Hill. I dont know if I want to go and do the classed events like STS, STX or whatever. I'd like to be able to do whatever I want to my car without having to worry about whether if will comply with the rulebook. I just want to do a few track events without getting to serious about it. So I figure some minor body stiffening, suspension work, and rims+tires will do for some roadracing.

So does anyone else know anything to say about the Safety21, Cusco, or Do-Luck type rollcages?

Thanks

 

If you just want to hit the local road courses, you don't need a cage or anything. Just make sure the car's in good shape -- cooling system, brakes, and tires -- and go enjoy the day.

For drag racing, you won't need a cage until you have a lot more mods and dragging experience....

If your car is even close to a daily driver, you won't want a cage....

 

From the looks of it the Cusco, Safety21 and So-Luck roll cages are easier to get in and out of then a full roll cage from Kirk Racing.

Below is a link of what a Safety 21 rollcage looks like, and I assume the Cusco and Do-Luck are similar. I am thinking about the 8 point roll cage. But if I feel that the bar by the front left or the one next to my head will be too much of a hindrance I may go with the 5 point. It may not stiffen the chassis as much but it will hopefully protect me better against a rollover if I should ever get into one.

About 1200 in cost alone...but well worth it..I think it's very well made...

 

If you get bars anywhere near your head I suggest you always wear a helmet AND put the purpose designed padding on it. Without both you may have a permanent headache following an accident ... if you're lucky.
