I'm wanting to get a 5 pt harness, but I don't have a roll cage, and don't want to bucher up the interior of my car. What is the best way to mount the shoulder straps? any pictures?

Thanks

A harness bar would probably work for you then.

As long as you are running autocrosses only.

As Kevin says, for low speed handling events only. If you are strapped in with a 5 pt. harness and the car rolls, your head has nowhere to go if the roof caves in. For high speed events a rollbar is the minimum needed.



The above one is from LG Motorsports - http://www.lgmotorsports.com .

I use the belts that have clips for eyebolts. For the shoulder belts I put the eyebolt behind the rear seat and as high up as I could. There is still some angle downwards towards the back of the car, but it isn't steep at all. All I have to do is drop the rear seat, but it doesn't want to latch in the up postition. There is enough pressure from the other rear seat back to hold it up when not in use.

A few things to consider.

Belts are designed to stretch in impact. If you were to hit something with a belt that was running to the rear "shelf" area of the car, you may see enough stretch to hit the steering wheel/airbag (not good), or it may just tear the thin sheet metal that it is mounted to.

I'd use a cage or a harness bar (harness bar for autocross only) or nothing at all (if it were me).

Just my thoughts, be safe.

Most belts require a certain mounting position relative to your body. Take a look at the belt specs and moutning requirements. Sparco I know gives you a 3-5 degree window of mouting options for correct installation. I would strongly encourage using a harness bar if anything for low speeds. However, they are not required and other than looking kind of cool, did nt really do much for me in auto cross. Plenty of other things to spend $ on. As for high speed raod racing, I am in the process now of building a car and I gutted the car, mounted my seat, spoke to my fabricator, and using the Sparo instructions, figured where to postion the cross bar as to optimize the belts performance.

Anyway, best of luck, I woudl just ask my self "what am I really going to so with tthe car" before I spend $

What he said! I know of some clubs where instructors won't run if you have a 5pt, and no rollbar for the reasons mentioned above. Even with a rollbar or cage, proper mounting is critical (angles, mounts, etc.).

Doing a full cage is best, we know.But even a 4/6pt is better than just a bar.And do a 6pt harness,trust me on this.

I've pulled enough drivers from crash's that they wished they had put a 6pt in nutkick.gif if you know what i mean!

And every one of those drivers thanks you for your assistance.

Anybody here ever heard of a hidden rollcage? I remember reading about this in an article on the Saleen Mustang that was built for Tim Allen quite a few years ago. It was the Mustang that had the Thunderbird headlights fabricated on it.
