    as long as the 2nd downtube bar starts at the harness bar node (strength, you want them all at nodes), and then terminates on the plate with the second downtube bar.

    You do not want to just put a support bar in the middle somewhere.

    On your cage, you also have a door bar backing up that brace bar. On the roll bar, there will be no door bar. So, i don't think it's too critical where the brace goes.

    Two-thirds of the way through X you are one-third of your way to Z. I will keep Y out of this, because the time it usually ends up taking is laughable.

    absolutely INCORRECT...

    you want those bars terminating at a node. The concepts are all the same for a roll bar or a roll cage

    Mine! Can't wait to pick it up!

    Ben is VERY knowledgeable and honest and has an extremely fast turn around time. If you're considering a 4 pt bar, definitely get one from him.

    I know nothing about cage/bar design but I'm assuming that nodes are important in cages to avoid shear. For the roll bar, there's no opposing force (like the door bar of your cage that Jon already mentioned) and therefore should not shear under normal circumstances. If you hit a wall with the side of the car hitting straight on and created an axial force through the harness bar, it should create practically no opposing forces in the direction of the brace bar since it's at ~90* angle and would not shear. Now, if you hit the wall side first at an angle, I feel that having it welded at the node would be more beneficial since it wouldn't twist and buckle in between where the harness bar and brace bar connect. This would have to be a pretty severe crash to actually do such damage to the bar and most likely fatal, but for argument sake.. I'm no expert but I just wanted to voice my opinion and see what the experts have to say.

    I do really like how the brace bar is underneath the window line if attached at the node.

    I'm not suggesting that connecting at the node isn't better. That's pretty obvious. I'm just saying that:

    Brace shown > No brace
    Brace at node > Brace shown

    The sheet metal at the wheel well is so thin that i doubt either of the braces in a simple roll bar are going to help. I can see it being useful in a cage though.

    One aspect no one has discussed is the ability to put wheels/tires into the back seat with the bar installed. In my car, with my bar, with no brace, i am able to stack the tires. I think with the lower brace, that would be more difficult.

    I am going to have him make this controversial brace, crash my car and test whether or not it is an important structual piece

    I agree with Jon, it is clearly better than no brace at all but is obviously not the most ideal method, which would be welded to the node. Good enough IMO.

    I might as well get a roll bar for my car since I never have people in the back seat

    UPDATED PRICE- I will be charging $475 for a 1.75 x .095 DOM bar like the one I have posted in the first post. Without paint will be $460. If anyone wants anything different we can absolutely work something out and price it accordingly. Also I wanted to mention I am including plates that go on the underside of the car that sandwich the stock metal. I am not including hardware at this time, however if someone wants me to supply that I can pick it up and would just pass the cost of it along to you. Thank you all for the support, this is fun!

    Ben...I thought Id post some info that might be helpful to you.

    First...Ive attached a page that has the dimensions of the coupe and sedan.

    Second...If you don't already know large items like these rollbars can be shipped nationwide via Greyhound Package Express(bus) for around $100.

    Thirdly...Powder coating these bolt in roll bars runs about $250.00 but if you're doing multiples they may be able to get that price down.

    Cheers !
    MikeD.
