ok guys, i am on my way to buying racing seats for my car. I want to buy a 4 point harness for the drivers side only but im stuck on where we can bolt it down to make it look good and feel comfortable when the harness is actually together so anyone out there with 4 point harnesses...please help me with this! Thanks!
bolt the right side to the floor..make a hole and bolt it good...
you would need the harnesses at a 90 degree angle...if your going to mount them please do it safely.

thats absolutely not the proper way to do it. if you intend to use it for everyday driving, i would suggest a harness bar, or better yet a roll cage. search on this. it has been debated hundreds of times, and the only safe way to do it is expensive.

If ur bound and determined to do harnesses, you need to run a bar or cage. The best way is to do a cage with a harness bar that goes 90 degrees straight back to the holes for the harnesses.
If you're not going to do that, your best bet is gonna be to run them to the back seats and mount them under the back seat. Corbeau sells harnesses that are retractable, snap in/out at the bolt and ones that snap in and out like a seatbelt so you might want to go check um out.
If you mount them straight down to the floor, if you get in an accident, kiss ur spine goodbye, so thats not a good idea.

sup guys..thanks for the feed back...im thinken bout just using the stock belts still..from what i read..if i dont have a harness bar its not safe..so i guess ill have to keep with stock belts..hope thats still comfortable for daily driving...
mine are bolted to the floor....havent had any problems/safety issues so far........but i guess i wouldnt suggest it

no safety issues??
just wearing them like that is a safety issue
RIP Saint ........ JBO
^ agreed...and the safety issues would be revealed in an accident that's for sure.

id seriously move them lindsey. they will likely do you more damage in an accident then wearing none at all with that mounting location. mount them to the bolts for your rear seatbelts as soon as u can before you get hurt.

wellll my boyfriend installed them and i told him about the roll cage and he says "theyre bolted underneath the actual seat brackets so theres no way that theyre going anywhere, the seat would literally have to go through the windshield for anything to happen, and that if i had harness bar/roll cage my backseat wouldnt be functional " and he basically sees no safety issues and says that he promises that theyre fine and i have nothing to worry about.
HOWEVER, now im freaked out. So if you guys can let me know what I need to tell him in order to convince him that they could potentially cause me harm then let me in please.... thanks!

The deal isn't with the harness coming out or the bolts failing or any of that when it comes to mounting them to the seat bolts. The whole problem comes with that if you were in an accident, because of the geometry, you would almost certainly compress your spine.
This is from SFI
_________________________________________________________________
Proper Installation is Important
The effectiveness of a restraint assembly is also influenced by attachment techniques. The principal precaution for installing the mounting hardware to the vehicle is to minimize bending stress in the fitting. This is achieved by making sure the belts pull from a straight angle against the hardware. The assembly should be installed so that the straps do not rub against any surface that can cause the webbing to fray. The anchoring mechanisms should also periodically be checked so that they don't become loose or weakened.
Proper installation of the restraint assembly also means achieving the correct fit to the driver. Belts should be as short as possible to reduce stretching for better control of occupant movement.
The attachment points must provide the optimum geometry to minimize movement of the belts. Lap belts perform best when they act at an angle between 45� and 55� relative to the longitudinal axis of the vehicle as illustrated in part A of the Figure. This angle permits the lap belt to react to the upward pull of the shoulder harness. A system installed with a shallow belt angle, as shown in part B of the Figure, permits the shoulder harness to pull the lap belt up off the pelvic area and into the abdominal region with the likelihood of injury to internal organs.
The end attachments of the shoulder harness must also be installed at appropriate angles. The ideal position is anywhere between 5� below and 30� above the driver's shoulder, as seen in part C of the Figure.
If the upper attachment point falls significantly below the driver's shoulder, then a spinal compression injury is likely to occur. In an accident situation, the shoulder belts pull down and back on the torso as they resist the forward motion of the driver. The resultant restraint force compresses the spinal column and will add to the stresses in the spine already caused by the force of the crash impact.
On the other hand, if the trailing ends of the harness are too far above the shoulder (greater than 30�), then two problems can occur. First, tension in the shoulder harness is increased and undue stress is applied to the harness and its structural attachments. Second, excessive angle will
cause excessive motion.
If the harness belts are too far above the shoulder, they will provide little resistance to forward motion of the driver's upper torso. The result is impact with the steering wheel and the possibility of neck injury. The shoulder straps should also be 3-6" apart behind the driver's neck to prevent slippage off the shoulders.

perfect, ill print that out for him. thanks for the info!

There are some safety tidbits in the links that I posted (see above) -- the first link is for a harness bar that might be able to be used in lieu of a full cage.

Read him this:
Basically it boils down to this: Proper harness installation requires that the shoulder straps do not drop below a certain angle as they come off the seat back. Too low an angle will cause spinal compression in an accident resulting in severe injury or death. In general, you should run the shoulder straps as close to horizontal as possible. That would entail either using a harness bar (as linked back to above), mounting them to the child safety latches in the rear seat (thereby hindering the use of the rear seat for passengers), having a modified roll cage to support the harness, or using them for show only if bolted to the floor.
Or what Seth posted... which is what I was looking for around the time of the post
another point that hasn't been mentioned in this post is if you roll the car, the roof collapes but your 4 point will not allow you to go sideways and duck, it will hold you up straight, you do the math, if you dont have a cage, dont use a harness.

The bottom line here, as you can tell by reading the other responses, is that your boyfriend doesn't know what he's doing and should do some research before deciding that he's the authority on this.
As mentioned, whether or not the harness stays attached to the car has absolutely nothing at all to do with the problems with your setup.
Send your boyfriend to this.

If he still stands by his opinions, then I strongly suggest you think twice before trusting your life to his opinions.
Yeah, this is the route I was planning on, but have one question, which after getting everything together I'd probablly be able to figure out, but how does the harness connect to the bar? Anyone have a picture?
Hoping to order everything in about a week...about another 2 weeks at most till it all gets here.
Get wraparound harnesses. They just wrap around the bar.

would a retractable 3 point work well? Either for attaching to floor or in stock retractor location. I figure the ability to move and retract would lessen the dangers of bolting to the floor. and mounting in stock location would be really slick.

If you wanted to go with a retracting one, hook it to the back seat belt bolt holes on the bottom or the top.

i have a custom harness bar im selling if interested

How much and can you still use the back seats?

i love how we watch out for fellow Jbodies...
and when safety is an issue... were gonna fix it.
i have a set of Crow Enterprises 5 point harnesses that i think i may wanna use as 4 point...but when i lay them on my tenzo r seats... they wont reach but half way down the back of the seat... are they too short for my seat??? i got them free so no biggie guys...
