Jumping on the soapbox for a minute..

I've been around racing a long time, spent most of my weekends at one track or another for about 30 years. Road race, Dirt Oval, Hard oval, drag. I've built over 20 race cars. I Support that many more for friends etc..

Bolt in cages DON'T hold up in real crashes, I've hauled enough drivers out of bent racecars to see a pretty good sample. If your going over 100 you need a 6 point welded DOM tubing cage. Or make sure you have a good life insurance poiicy. If your higher than that you need a FIA spec cage.

Roll cages in street cars are dangerous, you need a helmet to protect you from the cage. The factory 3 point harnesses allow a lot of movement in a wreck, its why they need air bags in cars. The factory seats wont contain you and you'll hit the cage, with your arms, legs head whatever and the cage wins. (Personally attended two funerals because of this.. )

Safety systems are a package, you need all or none in between gets people hurt badly.
A single roll bar is an exception if installed correctly. Its usually put in far enough back to protect in a rollover but not be where the occupants can hit it..

A full race quality cage will start at about $2200, and $3500 is about average for a hand built 6 point with all the gussets and attachments needed for a safe race car. The last 8 point I helped on required almost $2200 in TUBING without labor.

Ok.. Jumping off the soapbox and putting the keg of beer back on it, you may continue with our regularly scheduled programming...
