We could also make the diagonal a bolt in piece  because it does still get in the way of the passenger seat. I first need to find out if they allow this part to bolt in or not. They might be real specific on how they want it done.

dont really care about racing aspects. id feel a bit safer with a simple 4 point. the FD feels like a aluminum can of death sometimes.

I don't know yet. I didn't plan on doing a group buy but maybe we wil fir the first ten. We still need work out the details like the diagonal going through the hoop. We might need to make that an option or at least make it bolt in.

May I ask why the hoop is bolted in opposed to welded?

Removing it improves visibility but it could be welded in. The rear shock tower mounts might have to be shipped unwelded because the bar may not be removable with them attached.

Justin- Not saying you should copy but some of the design and installation aspects of the Raceshop roll bars are phenomenal.  If you want me to snap a few detailed pics, I would be happy to.

I'm familiar with the race shop bar. I'm trying to do something a bit simpler than that. He likes to use threaded bungs to hold things together poke the diagonal he uses from the hoop to the harness bar. He does his bar with a lot of options, I'm not going to offer as many. I don't think door bars are even nessary one a street roll bar. Just remember the more complicated the more it's going to cost so if it doesn't need to be there why have it.

Yeah, that's why I just want to make them simple and affordable. Id even even want to put in the diagonal through the hoop. If you guys see something that you think it should have feel free to let me know?

How much would it cost to have something like this made for the FC?

If its a custom job we just charge by the hour on that stuff, but I'm not interested in those type of jobs anymore, I just do production work now.

I'm starting on a second prototype of this bar. It's going to 1 3/4" .095 wall tubing. The bottom two bends are going to be rotated so that the inclination of hoop will lean forward a bit and sit a little higher in the car. Also more importantly it will be easier to install. It also looks like the shock tower mounts are going to have to be left unwelded until the final installation of the roll bar. So powder coating will have to be done first and then the installer will have to weld the rear braces to the mounting brackets after everything is fastened down.

Justin, I think it's great that you are working on producing this.  Excellent work.


unless you own a turbo ls9 rx7 you do not know what the fuck you are talking about.
