The only thing I really care about is that it is safe enough for track days, and something along the lines of grid life time attack if I ever get to that point. My car wasn't built for wheel to wheel racing, and will never conform to any particular racing class.

The only other solution I can think of is getting a harness bar that people would typically run with a 4 point harness, but i'm not sure if those will even fit at this point with the roll bar installed.

It's rare that any HPDE group would tech-inspect or care about your bar and harnesses, so no matter what you do, they're going to let you on the track. The question is, how much do you value your own safety?

Jimmy, you've led me down a rabbit hole of looking at old Group N and Group A roll bar designs. Gustave's site has some good examples analyzed as well.

I suppose if I looked at it only that way, I would never even sit in a gutted out, motor swapped, turbo death trap from the '80s and spend the god only knows how much I have "invested" in this thing in a modern car, lol...

I'm going to try to mock up some new seat brackets and think a bit more, but it looks like ill be reinforcing the trunk firewall/parcel shelf...

Next time I do a build like this I swear I'm stripping the car to bare metal and building everything to my specs...

There was an excellent thread on the subject of the E30 cage that ran on S14.net.

https://s14net.vbulletin.net/forum/s...alk-roll-cages

Lots of good reading and pictures if the links still work.

These are the most overlooked and under-used words in all of car-dom.

A plaque with these words inscribed on it should come with every set of tools.
I could not agree more.

So this would be the best angle I could achieve if I was to literally use the side mount rails to essentially sit the seat over the factory bolt
Locations. I could accept this driving position. Trying to use the angle finder, but there really isn’t the space to get it in position. This looks to be somewhere around 20 degrees. Safe enough?
