9-3/NG Hatch Rear Chassis Brace Poll

Since I have played around and found the best brace options on my drag car and found it to be a worthwhile upgrade.. There is one problem though. As made that one is designed for a shell, not a complete car.

There are some options.

Need to be removable or is function a priority and semi-permanent mounting ok? Drilling? I am more function oriented. Not going to make one that does nothing though.. ;)

For reference.

I agree. Some sort of quick release is a must. This can be done, just need to be creative.

Think of a quick release from a bike wheel.

Also, check out the Rock Shox Maxxle (used on mountain bike freeride forks). It's a through-axle system that is a quick release.

Maybe they will sell you the parts... ha.

would this be an option for the convertibles? I'm ok with permanent in that case as long as i can still access the fuel pump etc... things that may be necessary. I'd be more concerned with functionality. I don't want to buy the thing and not see any improvement!

CV has that already. Bunch of extra parts in there to stiffen it up. If we had those welded in a hatch it would be no problem but stripping to bare metal shell and welding is not reasonable to call bolt on. ;)

That white one is a stock sti right?

Good news is that the middle option is what my plans were for. :)

Just have to work up instructions and get an install method. I can tell you it will require one hole drilled and 3 bolts.

If possible, a nice design feature would be to keep the full use of the rear seat pass through when the brace is installed. For example, by having the horizontal bar go above the pass through, and the angled pieces attach near the top corners of the pass through, so that the pass through opening remains clear.

Nice work, this looks promising.

wasaaabi I have posted about the same chasis stiffening things before. I think a great example of such products can be found at: http://www.flyinmiata.com/index.php?dept=15

The ultimate example:

Back to rear chasis brace. Here is how I feel about it in order of importance.

1. If it can be installed w/o welding that is a +
2. If it can be installed/removed w/ simple hand/power tools +
3. If it can be used w/ the rear seat still in that's a +

1: No welding.. Thats always a mess.
2: Hand tools, 19mm, 5/15 hex key and 9/16 socket, 1" hole saw for carpet and a 3/3 drillbit. 2 holes in carpet and 1 in steel.
3: Has to be with rear seats.. :)

Here is is not powdercoated.. The trunk carpet got sold out of this car long ago. We made a wood deck. The carpet stays.
Still leaves full access to the pass thru.

Ties in cleanly.

Tucked out of the way mostly.

Only drilling is the carpet holes and lower mounting. Little tricky to get it in there but not impossible. Took cody maybe 15min to mount it and tuck everything away. I will probably do them for a while at an introductory price. ~$120 :) Also powdercoat color is open.

Missed the album link http://genuinesaab.com/gallery/HatchBrace

Ties into the thick part above the shock mount. Where it is quite stiff to get best benefits. Its nice to have one complete car and another just shell next to each other.. This is in the stripped out car so you can see.
Image


Simply fold the carpet back to get in there, a little tight but not horrible.
Image


Could have made it an easier install but then performance would suffer.. So we stick with this. I might do another down the road more complicated with exposed fasteners but for now this will be it.

I see how it is mounted on the bottom, but where is it mounted in regards to the sides, can you pull the carpet back and snap a pic?
Can you comment on what this piece does, I understand the physics behind it, but I would like to know what this will do for my car?
Thanks, and happy turkey day.
P.S. What color are you powder coating them, black?
Once again you beat me to part of my post^^^
