A current eBay auction for a 2003 XJR shows it with no rear sway bar. Was the rear sway bar not always fitted to the X308 XJR? Or perhaps someone has taken it off of this car?
The rear anti sway bar was standard on the X300 XJR, so was just curious of that were different for the X308.

My '03 XJR has it. Previous owner must have taken it off. Don't know why he would take it off, but you don't need it unless you plan to throw the kitty hard around corners....
It probably never had a rear anti roll bar, since there's no mounting plate for the roll bar bushings (see attached pictures).
There are two versions of the wishbone tie assembly and I doubt that the preowner changed it to the "no anti roll bar"-version when removing the anti roll bar. So it's more likely that it didn't ever had an anti roll bar.
Even though I don't know of any XJR, which had no anti roll bar...I thought they'd been fitted as standard for every supercharged and XJ Sport version.
Maybe the car got a whole new rear suspension or differential mounting at some point?

Totally agree, no one would remove the wishbone assembly - this car, or this rear end never had one. Maybe the wrong rear assembly came down the line and into the car it went
Thanks for the quick replies, I concur and noticed the wishbone mounting tabs and lack of the correct central mounting plate, so it had me scratching my head too.
I can't imagine anyone removing the anti sway bar, and even if so also changing out the differential mounting plate, so it's an odd one. An interesting mystery.
The JDHT website lists the rear A/R bar as "Supercharged" for USA models, which would imply that the A/R bar was fitted as standard to the S/C models. It is quite possible that the wishbone tie has been replaced with a non A/R bar version (my old X300 failed an MOT once due to failed wishbone tie bushes and had to be replaced so it's not beyond the bounds of possibility). I don't know if the US has an equivalent to the Uk MOT roadworthiness certificate which has to be done anually but its quite possible a PO has had fitted a non A/R bar unit due to cost/availability most probably....
Do you guys see the difference on the rear of what Vector posted? If you don't have the sway bar, you have the truss carrier like I have on my VDP. It literally is a truss like on a commercial building. This mounts to the body on the wide parts of it and down to the differential where it is attached. Thus replacing the old style sway bar.
I used yellow on the second pic to see it easier.

I noticed the same although I don't see how the truss bar arrangement can replace and/or perform the same function as a rear anti-roll bar. Am I missing something?
Someone will probably need to clarify this, but I believe they use the truss system on the CATS system? The stiffening of the shocks when in sport mode compensates for the sway bar I believe?
I've taken 40 mph curves doing anywhere between 70-90 and she sticks like on rails with no roll and that's how I lost a Lexus 460 one night and then I came off the ramp onto the adjoining highway and powered off it doing 155 .....and I coasted the next 5 miles and never saw him again. Mind you I was running Michelin Pilot Sport 225's then. They are sticky like a spider web, but I only got 9500 miles out of them. I'm using 255 Goodyear Eagles now (with a 55k warranty), I don't trust them as much with the larger sidewall and harder compound. But they are still descent.

You left the ramp doing 155mph? Impressive. Perhaps you can tell me where the button is for the hitherto-unsuspected warp drive, on my XJR.

....hahaha, I was almost maxed down to the speed control rubber mount under the pedal. It was awhile ago, but I remember looking down at the speedo after checking my mirror for that guy and I was like "DANG!" (insert other word).
BTW, the car for sale does have CATS, you can see the caps and leads on the front shock towers.

Every version of the 308 uses the same truss. It has noting to do with the anti-roll bar. The CATS electronic shocks have a soft and a hard setting and all 4 shocks adjust together. They do not provide any anti-roll control.
X308 XJR without rear anti sway bar?
