i have posted in the Road Racing/Autocross in hopes to get a response, but didnt find any, ive posted on s2ki and did not get a response either.

I have recently decided to mount a 4 point harness, but will resort soon to a 5 point due to the submerging i have read on many threads. I will be running a bucket seat, 4 point harness using the snap-in ends of the harness.

These will be connected to 1.25-inch Eye Bolt with 7/16-inch shank i have order from ioportracing and takata, since i believe home depot eye bolts do not comply for automobile safety regulations.

The harness will be connected to a 5/6point roll bar. The roll bar has hole predrilled for the shoulder eye bolts.

My main concern is what would be the safest mounting point for the lap portion of the harness? I have heard and seen on threads that the existing 3 point stock harness located below is where most people mount the eye bolt.

as for the other location, ive seen other people the other eye bolt which is mount parrallell to 3 point stock harness shown below.


if i do mount it to the transmission/exhaust piping location the other side will be backed with 2.25 inch Washer x 2 nuts.

i will also add a cotter pin to prevent the nut from unscrewing shown below.

as far as angles for the maximum and minimum limit i do understand the lap harness and shoulder harness should be as followed.



the position of my seat will be similar to this picture.



Can anyone verify if the holes i chosen for the lap portion of the 4 point harness are correct?

Also, can anyone direct me to were i can buy seam sealer to compensate the holes i will be drilling into my vehicle? thanks.

I have search and came up with these threads. any other information would be greatly appreciated.

Your lap belts would be within the limits.

I did not use seam sealer, but welds.

 

would also like to know..

, nice research btw

possible sticky?

 

You've done your hw. That hole is fine for the lap belt.

i thought i should do the hw myself since i was interested as to where to properly mount the harness.

 

Body/paint supply shops.

Don't worry too much about getting seam sealer. Shoot it with some rustoleum

 

man thanks for the info

you did your homework, and now i have some reading to do

 

thanks guys, i just went to my autostore and ask if they had any seam sealer, they had this rubbery compound that would seal to prevent rust.

no problem, haha

im just stuck right now trying to remove the rear tray. n i probably will buy a new drill just because im this ****.

ive even researched on this

 

The rear tray attaches to the 2 softtop-frame support panels on either side by ways of 3 screws. One of them is attached from the bottom and has to be accessed through the trunk, which means trunk plastic is coming out as well. There are also push-clips behind the roll hoops that hold it down, as well as a plastic panel behind it. Happy searching.

thanks, i am currently at work, and have removed all the screws that are push in's in the middle, and ive removed 3 white tabs from the trunk.

ive also printed myself pdf of this rear tray in the helms, would you happen to have any pictures. i think i have more than enough information. i am anxious to get out of work.

 

thanks for sharing your research.

what rollbar is that? autopower?


as for lap belts, you need to install your seat first in the final location your comfortable with. then you route the belts and make sure the angle to where you attach is natural and does not cause kinks in the belt. that will determine the best location for your anchors.

 

your lapbelt anchors really need to be located on the floor for maximum strength. so in a collision the brunt of the force is pulling straight away from the anchors. if its being pulled 90degrees to the side u will expose the weakness of the metal floor, if the impact is hard enough.

 

Even in the Takata manuals it states that the lap belts clip on to the eye bolts at that exact 90 degree angle.

 

The rollbar in the first picture is the Mugen bar. I am the only one so far that has the autopower bar.
