If you dont have a roll bar, you shouldnt be mouting harnesses-
Only time you should be using a harness without a roll bar is MAYBE during an auto-x...

Uh, who made that rule? I don't have the ability to have regular seatbelts because i did an S5 swap. It's my opinion that the s5 seatbelts are ****, and IMO unsafe due to the sliding belts.
I did get some idea's from one of the guys I met through work who races some older chargers and what not.
He stated:
The tabs that I have have to be bent at a 45 degree angle because cars that have transmission tunnels (referring to the lapbelt mount) will never be able to have a mounting point that pulls straight out. He said that this WILL pass tech inspection at the track. The same goes with the mount on the door side of the lap belt. The submarine belt almost must be bent at a 90 degree angle, then bolted to the floor. the rear mounts behind seat should go straight down to the floor through the chair and bolt at an angle that meets the holes in the chair. He also said, that if I wanted to cut the straps to fit me that was fine and would also pass tech, as long as the webbing was ducktaped or melted at the end that's fine. Also belts must be replaced every 2 years.
If anyone has anything to add or say "Hey, your wrong" that's cool I'm always lookin for more information!

Can't be mounted without a roll cage? I beg to differ. I know of several people who have theirs mounted just simply by drilling their own mounts in strategically strong locations.
This is the one thing that you MUST remember. The 2 upper belts that will be supporting your upper body must travel at no les than a 35 degree angle at a total minimum towards their mounts behind the seat, otherwise, the belts will put the squeeze on you in a hard collision. If they go straight down from the seat, they will probably crush your shoulders.

You can get eyebolts and clips that use the stock seatbelt screw holes. I have an RCI setup and it works great. I have a rollbar however, and mounted the shoulder belts on it. The reason people say not to have a harness without a rollbar is because if you roll it, the harness will hold you upright, and since you have no rollbar, the roof will go squish and so will your head.

When you get in an accident with regular seatbelts, if you flip, what happens? The roof comes after your head, and the stock seatbelts allow you to slide sideways (your torso and your head go sideways).
When you get in an accident with a 5-point harness without a roll cage, if you roll, the roof still comes after your head. But the 5-point harness holds you upright and you've got either a hole in your head, a crushed skull, a broken neck, broken back, snapped nerves in your spine, whatever.. either way, it's not good.

Exactly Barwick and Gene-
Also, if you dont have a roll bar its VERY hard to mount the belts at the proper angle.
If you mount the belts too low you run the very serious risk of severly compressing your spine in a front end collision. The belts need just enough downward angle to keep you from sliding up the seat while upside down- anything more is dangerous.
But do whatever you want- Darwin is watching.

Thanks.

they wont even let you race out side of stock classes at the high speed events i drive with out at least a 4 point harness. And in the fastest stock car class ( class X ) they wont even let you race stock with out them. No, you dont have to have a cage in your car. I race with the midwestern councle. So some where, they must have deemed racing harnesses more safe. They can sure make you drive faster though!

Roll cages arent good for the street either. Ever hit your head on a bar climbing in or out of a car with a cage? Imagine hitting your head on one while driving on the street with 45mph force behind it.

This is why you should never put people in the back seats of cars that have cages- Its a death sentance for anyone back there in an accident.
Of course, most RX-7's don't have to worry about that kind of thing.

Any kind of HPDE running these kind of rules is asking for a lawsuit. I can see harnesses being ALLOWED at low speed auto-x courses, where run off areas are big and paved and roll-over risk is minimal.... but to require harnesses without a roll-bar in a 'open-track' situation is just plain stuipid. About 3 out of 5 HPDE's I go to I see a rolled car. Those without bars/cages ussally end up with flat roofs, those with cages look much better.
