We make our own mounts for each customer and car, so I'm biased about what's good and what's not.
But the 2 biggest problems I see with all OTS mounts that offer enough adjustability to get the seat in the ball park on the X and Y axis, it's too far up on the Z axis, and more importantly, most (if not all) the bolts go into slots so nothing has 360 degrees of clamping.

The seats themselves, not a huge fan of. Too wide for me.
You wants to sell them?

Possibru. You'll have to sit in them first and see if they're what you're looking for. I'd have to figure out what to replace them with as well. Braian's Sprints fit me ok, but are still a touch wide.

I just wish Ultrashields didn't look like industrial ***. I know I fit in them but its a HUGE step away from a dual use car. For me anyway.

<p>Have you looked closely at them? I recently did a trip to Thunderhill and really had no issues with them. Surprisingly my girlfriend loves them, and the shoulder supports make perfect head rests for sleeping when you are 5'1&quot;. I don't know how the hell she sleeps in my car with how loud it is but she manages.</p><p>I personally think they look great. My only complaint is the height of the side bolsters in a dual purpose car.</p>

I actually like the Monacos, they're just too damn big for me. They'd be super awesome with a little more *** padding and about 4" less width.

not 100% true. you shouldn't bolt them in like a FIA seat. they need to be built into your roll bar.

Have you looked at the ones Track Dog Racing sells? That is what I have. He has them built with a nicer cover

It's the easiest install when it's done wrong.

Can you guys be more specific? If I just have a bolt in roll bar, not a full cage, how does one accomplish this correctly?

this is how aluminum seats need to be mounted.

remember a FIA seat will flex to reduce G forges on your body during an impact. Aluminum seats bend and need to be rigidly mounted.

So our single back brace should be replaced with a double back brace.

The aluminum seats need to be mounted into your cage. a floor will bend in a crash. It’s just 18ga steel sheet metal after all. Anyone that has drilled threw it will testify as to how soft it is. in a crash the floor will change shape, if the aluminum seat is mounted to the floor the seat will bend too. Mounting it to a cage will help prevent this, and help keep you located in the seat.

FIA seat Won't distort, they will crack under severe loads. If a FIA seat sees enough loads to crack there is little chance for survival. We are talking near to +110gs

an aluminum seat will bend with a 150lb guy pushing on it.

<p>I understand the bending, but you said the floor wasn't safe to bolt to.</p>

fiberglass and carbon won't bend. Aluminum will.
