Seatbelt Harness: Anyone installed a Sparco or Schroth?

[mattm]

I'm looking to add belts for autocrossing to my ITS. Has anyone installed Sparco or Schroth or another manufacturer's belts, if so which brand and any issues?

not yet. I have some fixed buckets and harnesses I would like to throw in for track days, but so far I haven't spent time figuring out how to mount them yet. You think harnesses would work well with our stock seats?

Got a roll-bar, bucket, helmet, and HANS? Not going anywhere without them.

You can make do without the rollbar depending on the rules of the track day organizer. Like everything, do it at your own risk.

The ITS seats will make a three or four belt setup challenging. The CTR seats have holes in the seats to feed belts through them. I'd probably feed them through the posts of the headrest. I do that now in the 1M. I'm not doing a track event so I don't think there is a need for roll bars and HANS. Helmets are required for an autocross.

Anchored to what? No part of the seat is designed to strap you down tight enough or arrest you in a collision with the way you're planning on rigging it up.

Do what you want but there's more to it than draping a couple belts over your shoulders.

If you look at the schroth rally harness mountings, they bolt on directly to the seat belt anchor points, such as in the back seat area to the seat/ bottom point and then the lap belts.

Yes, that's how my harness hooks up as well. just have to remove the back seats. I wold be tracking mine. I did run into a guy that had a direct bolt in Harness bar in his CTR, FK8. I think I would not do the harness bar and just anchor them as I did in my last car. Some track organizers require a roll bar as fixed buckets/harnesses could be dangerous in a roll-over if the roof were to deform at all. You essentially be locked in vertically. That scares me a bit. Not sure what I'll do in the ITS. Love the buckets and harnesses, but the stock seats are not too terrible on the track. Pics of previous car:

Scroll to about page 4 for install details. https://www.schrothracing.com/doc-share/ea_2-3_2020-11_online.pdf Remember this is for autocross only.

I installed a schroth 3(4) point bolt-in harness in my Camaro. Fairly easy install, use the same bolts as the existing seatbelt for the lower, then for the upper I chose to go to the parcel shelf upper child seat anchors because the angles worked in that car, for the Integra I'd recommend going to the lower child seat anchors because it has no package shelf. Can throw it on the floor in the backseat for street driving, then pull it forward for use.
Regarding what was mentioned about what organizations would let you use it: NASA was a no without a HANS, they said they'd consider it if you did have the HANS but it would be up to the organizers discretion, as it really should be mounted to a harness bar. SCCA will let me run it at autoX or TNiAs but anything over that they will require a HANS and a harness bar.
If you have the ability I would ABSOLUTELY swap the seat before putting a harness in, the seat change is the right way to do it. For my circumstances the seat swap was going to change my class so that was why I compromised with the temporary harness. Because of the restrictions around it I still end up using a regular seatbelt for most track days that I run, it's really only for AutoX that the harness does me any good.
