20 Minutes, pull out two front seats, undo 10 nuts/bolts, undo quick connect couplers and slide the bar out the front. No, rear seat can be left in place. Quote:

I'm definitely interested in bar/cage development for this car, even though it won't become more than just a light usage DE car (ie 6 events a year or so) for years

this is a good looking style bar. And probably an effective mount for harnesses if you are looking for one. And I do get the idea was to have something that bolted to existing holes without hacking up the chassis.
For people that are looking for a safety upgrade, here are a couple things missing in this design that would prevent it from passing a safety inspection for any track day org that evaluates safety equipment. 1. The rear bars are multi piece. 2. rear mounting location: rollbars transfer weight into what they are mounted on. The rear mounts are secured adjacent to the shock towers, but the mounting plate only holds it in place - It's not positioned in a way that would transfer force into a substantially reinforced portion of the chassis. It would transfer force into that hollow stamped steel piece the bar sits above. Best case the bar would twist and deform the mounting plate. worse case it would tear it. 3. I haven't seen the front mounting location, but unless it bolts to something like the frame rail, it would provide no protection in a roll over. There is a video on youtube of a mustang that bolted a rolbar to the floorpan and not a secure chassis mount. In the roll over, the bars just pushed through the thin metal of the floor pan and the rollbar ended up at shoulder height in the cabin. A backing plate won't change that.

1. I've never seen a bolt in bar that wasn't setup like that. Very difficult not to have a joint, but those joints are VERY strong and have been used with success before. The tube over tube joint method works too. 2. Could not agree more! And everyone else I've talked to and shown pics to agrees also. Two bolts only which aren't designed to withstand a ton of shearing force, combined with that raised stamped steel which will rip off the main body with enough force and the minimal and offset mounting arms..... 3. With a proper mounting plate that should not happen. Backing plates are to prevent the reverse from happening. Sheet metal in the floor pan is fairly thin that's why it needs to have the load spread out over a large enough mounting plate. Certainly it's possible, but most real cage designs won't do much more than welded on mounting plates or boxes.

Thanks for your opinions Dave and Matt.
I think we can all agree it's difficult to please everyone. There will always be those that want a true race cage and are willing to make the sacrifices associated with that. In fact Alex will be building a full race cage in a dedicated FR-S race car soon that will see professional race duty. Some won't appreciate the added value in a made in USA, TIG welded bar with $100+ quick connect couplers, for those something like an Autopower bar may be good enough. There are also those that just want a pure "show" cage like Cusco. I've had all of the above in various cars. This time around I decided to go this route as I prefer the fit and finish of what I feel is a much safer, lighter and more livable bar than what I could get somewhere else. In the future, I might decide to go with a full weld in cage, but for now I'd like to keep the option of going back to stock. Are you volunteering? |

I hope you don't think we are just attacking it for the sack of attacking it. I just think the design could be improved to increase the functionality of the bar. I definately appreciate that it was built in the US, TIG'd (although not really needed in a bar, but good TIG welding is awesome!) and uses (I'm assuming) Ballistic Fab ID joints. Although those joints are only ~$35 each, not 100+. Even with two of them at retail Autopower and Kirk both also make good bolt ins, and while their joint method is more common I like these joints. I agree that the Cusco crap is just for show. For the best fit and finish, you can't beat a truely custom, no compromise design, that's all I've been using lately.

I'd like to see one with the interior re-installed to see how much of it needs to be cut. Looks good though

Here are a few pics of the back seat bases re-installed and the carpeting installed. I don't have the foam pieces and don't plan to re-install the rear seat backrest since it needs to be trimmed and I'm planning to sell my interior complete un-modified. I'm sure someone will post pictures of the bar with the back seat trimmed eventually. |

Can you grab a pic of the main hoop mounting and backing plates?
Thanks!
