Anyone using a 4-pt harness with stock seats?
 

How is it? Easy install? Which are you using?

I'm looking for something for light track duty in a 4-point. I have looked at the new Takata Drift type which are nice and ASM .. and also the standard Sparco 4-point.

I would LIKE to mount them without a harness bar which seems do-able with this car.

I haven't installed mine yet, but I will be removing the plate for the driver side child seat restraint and using a longer bolt to attach to the rear luggage shelf for the rear attachment, lap belt attachments are typical, doubling up on the 3 point belt and latch points.

Mine is a schroth Rallye 4-point.

if you're doing light track duty then just have a little more confidence in your OEM restraint system

there is absolutely nothing wrong with a car that meets 2013 safety specs

if you find you're sliding around get a CGLOCK or just brace with your foot

Bracing with your foot is not much good when you use it so much.

Honestly I'm looking for harness suggestions, not alternatives.

I'm pretty sure the correct solution is a harness bar or stock restraint. Getting an extended length 4 point means the belt has a chance to stretch in an accident if not perfectly adjusted, or you'll submarine underneath the belt harness.

If you are really concerned with safety then get a 5 point and a harness bar, otherwise just use your standard 3 point seat belt.

the fact that you're asking about using a 4 point with the OEM seats just tells me that you are poorly informed about car safety in general

i gather you're a race photographer? I would stop trying to imitate the mistakes of others and start educating yourself on what's actually safe on a track for personal use.


Also just out of curiousity, how many Battle Endless or CSCS events have you been to as opposed to the Solosprint/Ontario Time Attack ones?

I'm not a big fan of harness bars. Reason is that the intent of the harness is to keep you strapped in place, and in the chance that you roll the car over, your head is basically stuck in place and the roof will crush your head first. With the oem 3 point style, it allows the body to bend sideways and away from the roof.

Now the chances of rolling a car over in autox is very slim, so a harness bar and 4 pt should be ok. But if the car is going to any sort of track, I'd highly recommend either the stock 3 point with a CG lock (and yes your left foot will get really tired from supporting you, I've had mine even cramp on really hot days) or a correct 5 point with a custom rollbar.

Just my opinion.

here is what FIA has to say about 4 points

scroll down to section 6.1 through 6.3

If you're concerned about safety you will not use a harness bar. One flip onto the roof that will cave in and goes snap of your neck because you were strapped in and couldn't move. Now if you had a roll bar it's a different story. Do it all the way or do none at all. CG lock will help you a lot. I've seen guys with stock belts out out better times than guys all kitted out.

I put a Schroth Rally 4 in my BRZ. Not too hard to install. I mounted the lap belt to rear mounts on the seat sliders. Intentional or not, there is a little notch in the sliders that allows the tab for the harness to slot in rather than actually sandwiching between the rail and the floor pan.

For the shoulder straps I used the anchors for the rear seat belt. The lap belt on on the inside, and the lower mount for the retractible mount on the outside.

Removing the side plastic bit is the hardest part. There is also a "gotcha" with the rear seat bottom. Remove the front bolt, then push down really hard in the rear and pull out. There is a tab that holds the rear seat bottom in place (it will pivot up and down on the tab).

If my belts weren't 10+ years old, I'd run them on track without hesitation. As it is, I probably will use them only for autocross.

CGLock in use here.

anybody mount here for 4 point?

4 points are a waste of time and money. they arent safer than either a 3 or 5 pt harness. the issue here is submarining. if you dont allow your torso to move forward in a crash, your body is going to go under the seatbelt unless you have a 5 or 6 pt.

I agree with these guys. The "in-between" solution (harness bar with 4 points) is not a solution. Keep it stock or get a roll-bar with proper harnesses.
