Would you swap back and forth for track days if you had regular seats? Do you have a preferred brand of racing seat? What do you like about it?
Hmm, any links/pics of the sub belts running through the stock seats? I was already thinking the 4 point ASM profi IIs, but even a non-ideal sub-belt setup might be better
The image from Schroth below is similar but instead of routing over the side bolsters and attaching to the seat lap belt mounting points you slide the belts between the lower and upper seat cushion to the bar. Porsche owners have been doing this for decades. In either case you're sitting on the sub belts. Shcroth looked at this and said either routing option if fine for HDPE. They even modified my sub straps to accommodate this layout. With the Recaro's in the current Mustangs there's less compression and a straighter pull by routing out the back. I have not looked at the new Recaro's but they should work the same.
You can't run sub-belts through stock seats. You would need to cut a hole through the bottom of the seat to properly run the belts and by doing so you would degrade the structural integrity. You absolutely need to swap out the stock recaros for a dedicated racing seat to run a 5 or 6 point setup.
I'm using the profi II ASM's also (mated to a custom rollbar).You can't run sub-belts through stock seats.

I have the 4 point Schroth ASM profi IIs mated to a Watson roll bar. They will be used for HPDE events, but will stick to the stock seatbelt for street use.
Schroth Quickfit/Quickfit Pro fits the GT350 and doesn't require a roll bar.
I have these installed then on my 2017 GT350 and they work great! Had to make a slight modification given they changed the stock 3 point seat belt setup for 2017. These pop right in for a 2015-2016 GT350.
In my track car, I used Deist harnesses. Top notch stuff.
Sorry to resurrect an older thread, but I'm thinking of purchasing the Quickfit Pro for my '17 GT350 and am curious about the slight modification you mentioned. What needs to be modified on the '17 cars?
I have these installed in my 2017 GT350, and they are great for HPDE. The modification is that you need to twist the rear anchor bracket 90 degrees for it to bolt in properly. I also needed to slightly clearance the plastic trim by the lap belt anchor to get an appropriate angle for the Schroth male end that bolts to the factory tensioner bolt. Total install time was ~1 hour for both sides.
