Thread: how hard to install cage?

Tweet

yeah i agree im sure the inspectors at the track around here get hassled every time theyre open. or they get punched in the face however thats another story lol

"but it's the local tech inspector(s) we all have to deal with at the events."

Point well-taken John. Thanks.

No matter what the actual ET they will inspect your car for the higher standard if you have a cage in it. For example, you will need a window net with a cage.

As far as mounting and padding, you must have missed my link to the paper I wrote on roll bar installation. I wrote it for a 5-point bar, but all you have to do is add a door bar on the passenger side and subframe connector bars on each side and you have an 8-point roll bar.....

built correctly, a properly designed and installed roll cage will stiffen up the car and take an amazing amount of flex out of a demon like you describe--10 sec 1/4, wow!! give it lots of looking and thinking and you can do it

well im putting ladder bars in for the rear suspension. and yeah 11.50s are fast.
thanks guys!

Yep, here's where compliance to the rules pays dividends in the tech line. Pay attention to the link I provided for you on the paper I wrote. You want to get the crossbar in correctly the first time (the bar your shoulder belts anchor to) and I have detailed that for you.

Something the rest of you guys should know too.....when you pull into the tech line and have done an outstanding piece of work, the word gets around and the tech guys will be much friendlier to you when you show up the next time. They'll know that you are a guy who does things right, by the book and they'll appreciate you showing up to race.

In the past, when I've found a particularly nice car (I'm not talking about chrome and paint, I'm talking about engineering and execution), I'll call the other tech guys over to take a look at it and sometimes even ask some of the racers who are in the tech line to come over and look at an example of how this particular part of the car should be done. Boy-oh-boy, you talk about a car owner popping the buttons off his shirt from being proud of his ride.....WOW. It gives everyone a good feeling and prompts the other racers to do a better job.

oh yeah. if i gotta wait another year to run my car im going to go over everything thrice
