Door bars are required to pass at the drivers shoulder, and I believe the knee. IIRC its been a few years since needing a cage done, but the rears went from the main hoop to just behind the shock mount and had an X brace between them. The door bars left the main hoop just above the shoulder and went down to the front door bar at the kickpanel. If you check the nhra website they have illistrations to help you out and pretty definitive IIRC. G/L

Here's mine. It was custom built by a friend of mine. He tucked the door bars in very close to the panels. The kits you buy don't come this close.
Notice how wide the bars go out to the side where the panel is. That gives me the most arm room.
I paid $275 for the material and $600 or $650 for the install (can't remember exactly). My cage weighed 46 lbs including the 6 plates.

Just finished my cage last Friday. I got to help some, but it was installed by Jon at DB Rods in Taylor, TX and he did an outstanding job. It's a Wolfe 6 point with 2 additional down bars from the main hoop to convert it to an 8 point. The Wolfe kit is a decent kit but I'm not too impressed with some of the bends which are flattened a little. I used RJS cam lock 3" 5 point harnesses with 2" crotch strap. They fit very well and are super easy to get in and out of.

The difference betwean my cage and both of the others pictured is that it is tied into the shock mounts, spring seats, and frame connectors. I am actually "using" the cage to help the car launch. They all look good. It just depends on what you are trying to do with the car and space requirements.

yep, for sure, i had my kid in there for mock up, and Ill be putting foam pad around all the rear bars when they are in there, and this is the last summer i will have a back seat(the girls wanted me to keep it one more year). I ran 11.46 with a 1.70 60' last year and after that pass, my t-tops dont fit right and my drivers door squeels when i open it, so i figure its time for the sub-connectors and roll bar.
