Is it just me, or are the seats in the 4.2 XKRs especially horrible in cornering? I mean, I literally slide right out of the seat--I have to brace with my knee to stop from flying out of the car, it seems! What do you guys think? Are later seats any better?

Definitely my butt loses traction before the tires do, and I don't think it's because the tire grip is that good...

 

Well, I guess I am the only one who has this problem! I wonder if the upgrade to say, and XKR-S, would be worth it just for better seats.

 

Or... here's a thought, instead of buying a new car, you can upgrade your seats. Also, if you think it's bad in your car, try driving an early (97-03) XK8 fast, unless you have the seat belts on, you will literally fly out of the car during cornering.

 

Your car has power adjustable side bolsters...have you fiddled with them yet?

 

I have fiddled with them a little bit, but they seem to do very little in the way of actually securing me in a hard turn. Perhaps losing weight will help! Or taping myself to the seat!

 

Losing weight may be something to consider regardless of the car's buckets.

 

So this brought a secondary question to my mind.

Between 2007 and 2013, how many versions of seats were available in the XK/R/R-S series? Not paying attention to materials, just coutours and such.

I admit the side bolsters in my XK are lacking, even when inflated.

My parts diagram only goes to 2010, but shows the following for the seat-back:

XK Luxury Pkg C2C24154
XK Sport Pkg XR849360
XKR Luxury Pkg C2C24154
XKR Sport Pkg XR849360
XKR Portfolio Pkg C2P16800

All show the same seat-bottom XR851091

Does the Sport or Portfolio offer larger side bolsters?

I know my Lux pkg has the 16 way adjustable. Is this an option offered with all the variations, or did you have to have the Lux Pkg to get it?

 

Interesting questions. I wonder the same thing. Does the 2010+ even have different bolsters than the '07-'09 models?

 

Swap the drivers seat out for a Sparco, lol.

 

Ouch!

 

Haha, I'm not sure if I'd go that far! However, I know there must be others out there that feel the driver's seat is not good enough for a car with this level of performance.

 

I do have a 5 point harness hangin' in the garage I have though about installing! Guaranteed to solve the problem!

I would think *losing* weight would make the problem worse...you would be lighter, smaller, and would move around even more in the seat.

Being bigger would make the seat feel snugger around you, but the extra weight would affect the cars performance negatively...

Yes, the tape is the best answer.

 

For me from the 08 xk to 10 xkr there is no differences within the seat settings. In design maybe the stitching. And the ventilated ac.

 

Actually, I tried the bolsters again today, and made them as stiff as they would go. It really does seem to help! I will try it again on some curvier roads (my commute doesn't give me much chance to throw the car around!).

However, my bolsters seem to deflate by the time I get in the car the next time. So maybe I just need to remember to inflate the side bolsters when I want to do some more serious driving.

 

Bluntness is one of my failings.

 

if you can't live with them and can't live without the jag, maybe a set of recaros are in your future.

 

I think the bolsters are part of the memory function.

 

This time I took a hard turn and I had the bolsters fully activated, but it still seemed like I was sliding out of the seat. Definitely better, though.

 

I'm currently chatting to a racing seat company regarding fitting racing seats (similar to XKR-S seats), the process isn't as simple as you think. The dashboard will light up like a Christmas tree with many errors. An airbag lives in each of the standard seats, these can be over written with a resistor, but the main problem is the pressure airbag sensor in the passenger seat. The switch isn’t a closed or open circuit as the system knows when it’s been disconnected and triggers and fault code which then needs to be reset. This code stops the SRS system functioning correctly.

We're working on this now and will report in along with pics of new seats fitted!
