OK, so what's the scoop on this option, and is it desirable?

Also, that do the wheels look like that come with this? It says it comes with 245/45YR19 summer tires. Are these the standard tires, or different?

From the website:

Active Power Stabilizer Suspension System
Working in conjunction with sensors and a computer that detect the amount of force needed to help keep the vehicle flat in a turn, the active stabilizer system increases roll resistance by twisting the stabilizer bars. Which pre-loads them to help them behave like thicker sway bars without having to compromise a smooth ride.

 

If I were going with the LS600hL, I wouldn't get one without the APSSS. Handling/cornering are reported to be much better with the GS450h with this option.

 

yes, if i were getting ls460l today and it has this option, i will FOR SURE get it. it improves handling dramatically without compromising much on the ride comfort. i test drove the gs430, gs300/350, and then the gs450h, and i felt the HUGE difference. even my wife on the passenger seat said "wow, this car handles great!" that's how much it helps on the gs450h. so i really expect something similar on the LS

 

What a shocker. Being told by the dealer that it cannot be ordered now, despite being on Lexus' website.

They really need to get this ordering/misinformation/website thing together. It just comes off as so amateur - especially on the most expensive car they've ever buillt.

 

After driving around in these big boats like the 745/S class, it handles very well.
Like what everyone said, I wouldn't get an LS without one.

I know it's not meant to corner like a sports car, but at least the car feels confident and your passenger sitting on the left seat won't end up in the right seat
