Never heard of, or seen any. The fuel tank placement between the towers would be an issue. I have considered making one up to see if there is any time to be gained from it, but my gut feeling is no. The front brace I made does go a long way to making the front end more rigid, but I dont even know of anyone investigating the need for a rear brace.

can someone explain the benefit to a strut bar on a double wishbone suspension set up
i can see the benefit on a fwd tin can where the suspension strut is the main component of the actual suspension, but on a soarer its different...
the soarers chassis isnt too bad for a big coupe my driveway flex test shows its better than any local car thats ever been on it...
everyone know the track is different than the street, so go ahead on your track weapon, but on a daily i see no benefit..
everyone talks of less flex, i can tell you with new bushes and the front aired out there isnt any flex, unlike what you would get in a crummydore of the same year....
i used to have a car that the chassis twisted so badly you could hear the back window pop every time you went in the drive, but back in the 60's im sure they didnt care back then... everyone know they dont build them like they used to! sure! they build them better.... well some anyway

Yeah fuel tank placement means there is no off the shelf rear brace. I was toying with the idea of getting something design but really i wouldnt need it and im still thinking of how to design it so it works correctly. Fronts brace is good to have, rear brace is also good but yeah too much effort with the placement of our tanks.

I know of some people using it in their cars (not Soarer's)... but, probably not worth it as the performance gains wouldn't offset the effort of investing time and money + would there be enough demand for it?
The fuel tank would most likely be the only issue and I'm sure if there's any budding engineers out there they can design there way around that problem.

Toyota saw fit to put them on Aristos as standard equipment, so the worlds biggest auto manufacturer seems to think there is some benefit.
On my JZZ30 track car there was enough flex so that when one side of the car was jacked up (via the suspension arm) the bolt holes for the strut brace were completely obscured due to the movement between the towers. With my brace fitted the movement is gone.
Dave Cazes has also got some figures on this and the flex between the towers/guards and the fire wall, which he says is significant. My brace triangulates back to the fire wall, hopefully tieing the three points together and eliminating a lot of this, and allowing the suspension to do its job as designed.
But, as you say, on a road car it would be up to personal preference as to if it is beneficial. I myself have a brake master cylinder brace on the road car due to the way the pedal feels when all that flex is removed, but others may not see the point. I do not have a strut brace on the road car as I don't feel the need for it.
It is a matter of opinion, and opinions are like assholes- everyone has one and no one likes to think their own stinks...
