Ive been wondering how do you install a 3 point racing harness when you dont have a roll cage??

I thought you just bolt it down to the floor but where is a brace to attach it to.

i thought i heard its very dangerous to bolt it to the floor because in an accident it compresses your spine and there is to much downward force

i'm not sure someone wanna back me up

Yes, it is incorrect to just mount it to the floor. The shoulder restraints need to be mounted to a bar that is directly behind the holes where the come through. This way, on impact, you are held correctly into the back of the seat and not pulled to the bottom.

First off, you already have a 3-point harness....the stock seatbelt attaches at 3 points. You're thinking of a 4,5,or 6-point racing harness.

Both the above guys are correct. You'll have to have a harness bar made, or install a cage to mount the belt properly. There is an exception to this rule however. If you're only using the harness for autox where the chances of a collision are less than getting hit by lightning, then it is acceptabe to clip it into the rear seat belt. This is how my harness is done. It is not there for protection in a crash, it is only there to keep me from sliding around in the car at over 1g and help me feel what the car is doing. I never use it on the street.

I was under the assumption that you could mount them to the floor as long they atleast came up and over the bar behind the seat and then came forward to the seat - PLEASE correct me if Im wrong on that!

Um, why would you need to mount them to the floor if you have the bar there? Bad bad idea. There are wraparound harnesses that are made to go around the cage bar behind the seat and require no brackets.

so can you get a bar that attaches from each seatbelt post on the door frame? That runs across the back of the driver/passenger seats. I remember seeing something in Super Street that a company sold a bar that bolts onto the seatbelt part and connects to both of them so you can install harnessess.

Yeah i thought 3 pt harnessess had 2 straps on the sides and one that was attached to the roll cage?

Yeah, if you don't have the money to do it right, you're a lot better off with stock stuff (as long as its in good condition structurally).

I can't believe that DOT or somebody hasn't cracked down on some of the cheap ass 'racing' seats out there. Very unsafe in some cases. Did anybody see SCC's article on seats a while back? If you noticed, all the seats with FIA approval were mega bucks. Thats because they've gone through the testing and you will have the piece of mind of knowing that they're not going to kill you if used properly.

ok to make this easier.

Where can i get a harness bar?

And if its custom how much do you think it would cost?
