Will the 2010+ XKR CATS suspension shocks / struts fit in the 2010+ XK ?

I have CATS suspension, i'm looking to tighten it up a bit in the corners by
replacing the shocks with the XKR ones.

Thanks

cheers

 

 

Spires springs will tighten up your ride and improve the floaty feel of the vehicle .

Save your money and keep struts in place until they fail and go with performance springs

Another suggestion is going the xkr-s springs this will also improve handling

 

I hope this isn't construed as hijacking the thread, but perhaps asking for the same advice.

I have very limited mileage and seat time (<2000 miles total) in my recently acquired 2014 XK Touring coupe with 39K miles, and am trying to figure out exactly the ‘floaty’ feel of the ride. The steering, handling, and ride over cracks, potholes or rough road seems absolutely fine. No extra noises, no shudders or vibrations. Rock solid. But on highway that is less than totally smooth, I seem to be bouncing (or floating) down the highway, to a point that I almost get nauseous at times. I don’t experience this in any of my current vehicles (2014 C-class, 2002 Passat with recently installed Bilstein B6 shocks, and 2012 Lincoln MKZ with original suspension). I can’t decide if there is something wrong or this is the intended feel. I’d like to change it but don’t know how. So I read with interest the notion of changing the springs and hope that advice could apply to my car. Anyone else able to comment? Thanks

Edit: I wondered if there was a problem with the electronic shocks but no error codes.

 

Chris as has been said earlier I think all XK's have the same set-up, except on performance models, so fr instance my XK Dynamic has a bilstein shocks and shorter springs which are rather...erm...hard. They are IIRC the same as fitted to the XKR-S mentioned by Auzzie Steve.

So some questions:

1) Are you running 20" rims?
2) Tracking/Alignment last done?
3) Tyre band and pressures?

Wouldn't have thought that you'd have any bushes perished on a 2014 yet, so can rule that one out

 

Is this bouncy ride in normal mode or dynamic mode? I have found that Dynamic mode and highways/Autobahns don't mix well. In normal mode all is smooth enough and the suspension seems quite refined. In dynamic there is a more pronounced up-down bouncing over road level changes, but it is not floaty, rather too stiff. Dynamic is for twisty roads and the limited damper range is not required on relatively straight roads.

 

Thanks for the input; I appreciate your help. What I wonder is whether the ride is actually stiff, and the bounce I am describing is just a stiffer ride than I am used to. Almost feel like if I put a couple of cement blocks in the back it would 'fix' it. This is all in normal, not dynamic mode. Tires are 19", inflated properly, and no wear. Haven't checked the alignment but it tracks very straight. Compared to Mrs.'s Merc, I really like the seats in the XK - my 2 long drives were very easy on my creaky back - but the ride is, well, different.

Maybe I need to get a suspension tuner to do a ride along.

Maybe I'm just nuts.

 

When the 5.0 engines were introduced the suspension was also stiffened and the difference between the XK and the XKR was also reduced. Some journalists commented at the time whether Jaguar had gone too far for their usual customers.

You said "The steering, handling, and ride over cracks, potholes or rough road seems absolutely fine." This is a fair sign that the car is not majorly misaligned. If you are getting constant deflections over bumps, check the tires for wear on the edges - tells you quite a lot about how good the alignment is. Also as you sweep left and right across the steering center point, the change should be linear. If it seems sticky, again, alignment could be out (but might still be withing the "acceptable" range).
