Hey, guys. I'll admit that I haven't done much research on the topic myself, as I'm looking for suggestions first. I will be doing track schools with my RX-8 and would like to have a set of harnesses in the car. I would like to have belts that buckle in, so that I can quickly remove them if someone needs to sit in back. I will probably use them most of the time on the street. Do they make ones that buckle the top straps to the child seat harnesses in the back seat? There's the anchor point just behind the rear headrest, and the two behind each lower seat cusion and seat back. It would seem like it would be easy to clip one into the anchor point above the rear headrests, and the lower belts could bolt down to the floor.
I checked out Schroth first, as I'm familiar with them from BMWs, but I don't know who else is making good belts for these cars. I want 4-point harnesses (I would consider 5-point) with a quick-release buckle (not the old-school seat belt buckles!). I think I'd want 3" wide straps, but maybe 2.5" would do. I really don't know about that. I'd like to have an option for them to be red, if possible, and as inexpensive as possible while meeting most of my criteria.

Please give me suggestions and pics if you've got 'em! Thanks!! :D

 

I guess a harness is an "interior" item but it is more of a racing item and thus you will find way better answers in that forum.

This issue was a concern of mine and there are a few older threads on this exact subject. I too noticed that the LATCH system anchor points (top one specifically) would make an ideal anchor point for the correct angle of a 4-5 point harness system. The consensus was that the LATCH system is not strong enough to keep an Adult in place during what would most likely be a high-speed accident. It will hold you in place well during the turns but get into an accident and it would rip right out.
What I am waiting for is to see what this company turns out

The roll bar they make “COULD” have the proper mounting points for a safety harness have to wait and see.
