Per Lexus website:
"The RX F SPORT is also exclusively equipped with front and rear lateral performance dampers to provide additional rigidity to the chassis while also minimizing vibrations. The result: enhanced handling, a more linear steering feel and a ride that’s as comfortable as it is invigorating."

There are obviously exhaust vibration issues. It costs $$ to add these dampers on each vehicle.

Don't mean to drift this thread but, I took my 14 RX to the dealer last week for my vibration issue. The tech. said it has a defective muffler so, I'm taking it in tuesday for a replacement. I really hate to have him cut into the factory welded exhaust to clamp on a new muffler. The car only has 10,000 miles on it. Hopefully the new muffler will cure my vibration issue.

Yes on both! It was definitely a minor annoying vibration on acceleration from a stop or turning a corner slowly. If you took off from a stop in a brisk fashion it wouldn't happen. Had the tech. ride with me last week and we agreed it was faulty exhaust. He stated a bad muffler and would replace it. I must have misunderstood him and thought they were going to cut the old one out and clamp in a new one. Instead it was a new welded assembly including the resonator bolted on from the cat. back. I'm happy with the results and the vibration is gone.

Front lateral damper
Had the car on the hoist for winter tire install and took of the front plastic shield to have a look at the supposed front "lateral performance damper".
It looks the same as the rear one and has the same high pressure gas damper. This can only dampen some higher frequency vibrations and does nothing for better cornering.

It is supposed to improve steering, apparently by increasing front end stiffness without increasing vibrations like a typical strut tower bar. I think you could use a stiff metal bar with holes drilled to fit and get the same effect and probably would never notice the vibration difference. Lexus wants about $500 to buy one of these things!

If the front frame moves at all, this pneumatic strut does essentially nothing to resist that.

I had a CT200h F Sport with the same lateral dampers. However on the CT they placed the front one where one would place a strut tower bar. In the engine compartment, between the two strut towers, where it may actually do something. I think I read that it is much stiffer than a shock absorber.

I installed a Curt Tow Hitch last Monday, which still allowed the use of the rear damper with some modifications (cutting plastic under-tray). The hitch comes with a special bracket that re-positions the damper upside down and a few inches toward the front.

I installed a tow hitch today and couldn’t reinstall the damper because the bracket wouldn’t support it.

You need the Curt trailer hitch that is designed for the F-Sport and allows for the lateral damper.

However it appears to me that if you install a hitch you no longer need the lateral damper as the hitch performs the same purpose in making the rear stiffer. I think it will be even stiffer with the hitch alone as the performance damper has a shock absorber in the middle.

The first step of the Lexus instructions for installing the hitch on an F-Sport says to remove the damper and throw it in the garbage.
Even when I installed the Curt, I didn't bother putting the damper back in, it seems completely pointless when the hitch is installed.
