Basically everybar that connects 2 points and doesn't somehow form a triangle, doesn't do anything. The floorbar is just an end to end link. All it does is "stretch" the floorboard.

The whole problem with the targaflex is that once you take the targa off, the only thing connecting the front and rear axle is the floorboard/beams. Thing is, the floorbrace is not connecting the floorboard to anything but the floor itself.

The shortest path to a working brace to reduce targaflex would be from the passenger side floor to the drivers' side top of the A pillar and from the drivers' side floor to the passengers' side top of the A pillar. Then from the drivers' side floor in front of the frontseats to the top of the B or C pillar (where the targa would normally bolt into). And vice versa ofcourse. Problem with that solution is that it very rigid, but impossible to drive in :p

Moy: I'd need to see how the parts bolt in and where but most times there's little to no triangulation so yep they do dick ;)


Yo! It looks JDM tyte!

Thanks for the input guys. Would using a combination of the rxb and the lower arm bar have more effect on the wet noodle effect?

I know that a weezl wing would be best, but I personally would like to have my top completely open.

i have both bars, the JIC lower tie bar, and the Do-Luck RXB, and i still have a little "targa wobble"
i don't remember how much they helped, but the Do-Luck bar in my opinion is not worth the money i paid 7 years ago when bishop or dan mack had them imported

I always love how that picture of the JIC bar almost covers up the factory subframe brace 2" in front of it.

The cross bar is a rare and hard to find piece. Good luck finding one.

No, I watched three used Do-Luck RXB sell last month. The problem is that no one is going to pay the ending price of the brace plus shipping from Japan for an item that does nothing but look good.
There are much better options to reduce or eliminate the loose feeling from removing the sport roof.

I will point to the mod list in Noah's sig. Duplicate what he has, and you will have one hell of a nice handling car! That is the most sure-footed car I have ever ridden in. He scared the pure shit out of me on the first interstate looping exit, when hitting it at 20 pounds of boost and never slipping or leaving his lane. There was very little body roll at all. After the 2000+ mile trip we made to CHI2K7, I was used to it, and loved it.

IJ, what are your thoughts on stitch/seam welding for rigidity?

I don't think it does too much for rigidity unless the car has badly designed panel joints, but it DOES help in an accident situation as the shell structure is a lot stronger. (this is from personal experience)(stitch welded is preferable)

You need something like this to eliminate the noodle effect:

Targa comes off and goes on with the brace in place just fine.

Long ago I had a targa supra, and I was never bothered with the car flexing. I really think its all in your head. If you are really that worried about it, instead of paying high dollar for all of these parts, just buy a cheap hardtop shell and transplant. Then again, if it went that far, i'm sure nothing would suit you.

can you quickly break down the difference between stitch and seam? as far as i understand, stitching is a similar technique to welding replacement sheet metal in, where you'll weld a small section and skip a large section working in a loop to give time to cool. how's this differ from seam?

WHOA!

Where can one get one of those? I've never seen anything like that before. All the cross braces like that I remember require you to remove the bar to reinstall the targa.

Only a few where made, Lance (Rajunz) has one.

THe JIC bar isn't going to do jack squat since the stock brace is right in front of it. I accidently left that brace off and I did notice the car feeling weird (thought I had left something loose so got under the car and noticed it missing).

The do-luck bar is a royal bitch to get ahold of and the ab-flug bars might actually help as well.

Stitch think dotted lines on toilet paper the idea being if a crack starts it ends at the gap in the weld, Seam is continuous and if a crack starts it goes right to the end and the structure fails.

So how much do you charge for one of those?

Also, Do the interior panels fit back on, or not. I didn't know if you just had them off when the picture was taken.

projectsupra made a few of them a while back. I have zero interest in selling it:icon_mrgr
The interior needed to be trimmed a little bit.

With the roof removed, there is a noticeable amount of flexing. Going from a targa car straight to a hardtop car, you really notice the difference in rigidity.

Has anyone ever driven a targa Mk3 when they were NEW? Just wondering if they came from the factory with the targa wobble annoyance. If not, then all new bushings, door hinges, etc, might solve it.
