Roll Bar install for Solosprint
Well I do have regrets fitting in the cage. But I've come to realize that the car is not worth much anyhow cause I would be lucky to even get 1/4 of what I paid for it. So might as well drive it into the ground.
Problem with buying another track car which I was going to do is money and space. I don't have anywhere to put it and I don't want to pay insurance for three cars.
The towel is over the bar because I snapped from the constant squeaking noise from the seat rubbing the bar!
You guys will have to sit in it to see if its all that bad. I am not used to it yet.
Insurance does not know about it.

I think I might be able to pull it off since I've got a little more depth without the bins, and more room above the strut towers since I'll be cutting out the speaker pods.
Curtis, I hope you aren't reading this thread...

That is one strong roll bar you got there. See what obrien has to say. He may be able to build a roll bar suited to you.

Ian,
Not to rain on your parade but are you sure O'Brien met the following rules in the rule book? Maybe I'm a bit jaded from working in mindnumbing engineering land...
2.5.16 In cars with frame type construction, the roll bar and braces shall be attached
to the frame of the car wherever possible. Mounting plates attached to the
frame, regardless of whether welded or bolted, shall be at least 3/16 inch thick.
.17 In the case of cars with unitized or frameless construction, or cars with frames
where frame mounting of the roll bar and braces is impractical, mounting
plates shall be used to secure the roll-bar structure to the floor of the car. The
minimum mounting plate area shall be 20 square inches. The important
consideration is that the loads be distributed over as large an area as possible
and as close to vertical structures as possible. Mounting plates bolted to the
structure shall not be less than 3/16 inch thick with a backup plate of equal size
and thickness on the opposite side of the panel with the plates through bolted
together.
.18 Mounting plates welded to the structure shall not be less than 0.080 inch in
thickness. Wherever possible, the mounting plate should extend onto a vertical
section of the structure such as a door pillar.
Did Obrien pick up the rear main cross member which bolts the subframe up? If so maybe you can get away with 0.080" thickness? Else you gotta be at 3/16"...
What tubing diameter did Obrien use? Your car's mass is between 2001-3500 lbs which calls for 1.750 x .120 Mild Steel. I only ask this because you will be asked these questions before your log book is signed off.

I'm not 100% sure as the rule books leaves some ambiguity. Section 2.5.17 can be argued that if you can't weld a plate to the structure of the car and you are forced to attach the plate to the floor pan than I interpret it as you need 3/16" plate of 20 square inches area to distribute the force of an impact if you flip.

Yeah, it's not clear if this part,
"Mounting plates bolted to the structure shall not be less than 3/16 inch thick with a backup plate of equal size and thickness on the opposite side of the panel with the plates through bolted together."
and this,
"Mounting plates welded to the structure shall not be less than 0.080 inch in thickness. Wherever possible, the mounting plate should extend onto a vertical section of the structure such as a door pillar."
are mutually exclusive in the rulebook. If they are mutually exclusive, then they should be 2.17a and 2.17b or something like that...

Also, can you open the storage bins still? Especially the passanger side one? That's where my battery sits now so it's kindof important for me.
I doubt techs would have a problem with that cage, it sure LOOKS strong as hell.
I don't see how with that rear X brace you could fit tires in the storage bin area.. they might "fit" there but you wouldn't be able to get them in!
How tall are you? I don't sit with my chair anywhere near that reclined or I can't reach the wheel properly.

, and when I pay someone a ton of money for a job and somebody that builds cars/cages for CASC, SOLO, and other forms of racing and comes highly recommended and when I asked him if he was aware of the rules and requirements he assured me that he has built a ton of roll bars/cages for solo racing, then I would expect me to do nothing but hand him that stupid wad of cash and away he goes! If it does not meet the "code" then I will expect him to redo it free of charge. Or either remove it and refund me Not to mention the slander that he will get from me on the casc, solo and racing websites.He did build all of mazdee's spec sentras for the racing series....

Both storage bins still open up. I'm 6.1. I fit in it fine now that I adjusted my normal seating positions. BUt no idea with the helmet. helmet on i need at least 2" more clearance.
