I've joined the club! Throttle response is more aggressive than I anticipated smile Next question is does anyone know a good indi servicing specialist in Essex?
One of the best colours for it!

Enjoy every mile.

Cheers, I specifically waited months for this colour to come up in the right spec! smile

A convertible in that spec and colour has just turned up at BCA, it looks fabulous but a bit scruffy round the edges. Just my sort of car hehe



I'd rather a light interior like the one much like it that went through at Bristol 2 months ago, which also had the same wheels as drmotorsport, but you can't expect too much from the used car factory. I think I'd change the roof for a burgundy one when the rear glass inevitably drops out.




Watch out for kerbs when parking!

Speaking of which, how do you find the C63 now you've had it a while?
In fairness I've done little with it except drive it places lately - my mother passed away late in December so I've been busy helping dad with stuff, driving up and down to see him etc. Hopefully get to stretch its legs a bit soon now we're out of winter (touch wood) here in Scotland!

It's an interesting thing though, very like the XKR in some respects - that sense of vastness about the engine, the dual personality thing of being just as happy pottering as giving it the beans. Not as well appointed inside, definitely not as pretty outside and not as comfortable in terms of ride. While the XKR is faster the C63 feels a bit more dramatic and feels like the handling matches the performance. And here's something you probably never thought you'd hear - I miss the fuel economy of the XKR!

Yep 2014 XKR Dynamic R with Black pack. Supposedly all the goodies from the XKRS but without the s/c pulley and the bodykit which i'm not keen on anyway.
The XKR-S didn't have a different supercharger pulley from the XKR - the engine was entirely the same, the only powertrain hardware differences were in the exhaust, other than that it's just the ECU mapping. Your Dynamic R will have the same crossover mid-section as the XKR-S but I think the back-box from the standard XKR.

XKR faster ? Surprised to hear you say that .

Glad you're enjoying it.

I'd have thought it's a fairly safe bet for the 5 litre XKR to be a bit quicker. I think weights will be similar and it has an extra 50 ponies.

Both plenty I'm sure!

Certainly feels like it - being supercharged the Jag's pace is more accessible. Not to say the C63 doesn't feel quick, just not as much as the XKR.

The C63 Coupe is a little bit lighter IIRC but gives away a bit of power, but torque is fairly similar between the two. Pre-facelift C63s had a fairly awful slushbox, not a patch on the ZF ones. Facelift examples like mine got a MCT which is much more user-friendly and effective.

That's stunning, well done. XK Dynamic R? They have the XKR-S ECU mapping (or something very close to it) which is a bit sharper than standard. I installed that on my 5.0 XKR and didn't notice massive difference in outright performance but the car definitely felt more keen.

I didn't really take to the facelift 5.0 look but I could see myself going back to one of those once I've had my fun with my C63...

That’s an absolute stunner. Congrats. Beautiful looking thing she is.

On the throttle response comment and the inevitable traction issues, I’m now 4 months into ownership of a 2011 XKR, now looking at possible replacement tyre options. I drive mine always in sport on the paddles (always pull away in 2nd) and when Mrs D isn’t in the car I have dynamic mode on. The traction with the Dunlops on mine is diabolical out of junctions no matter how much I modulate the throttle - I’ve had a lot of quick cars now, including 3 previous s/c Jags, so I’m beginning to blame the Dunlops.

Does anyone have better experience with the Michelin PS4S or the new Continentals?

One of the first things I did on my XK was bin the terrible cheap tyres and fit four PS4S all round. very very good tyres, although I've heard good things about the Sport Contact 7, so I think really so long as you're fitting one or the other, you can't go too far wrong.

The new continentals are superb and seem to be wearing ok on mine, and PS4S are very highly regarded.

The Dunlops are widely known to be crap, I binned a set with 5mm of tread on they're that poor.

I've got Bridgestone Potenza on the front of mine and it is very nose stable.
The Dunlop's on the back spin up at the lightest touch so I'll be swapping to Bridgestone all round when I get it back.

I recently fitted Sport Contact 7's on the rear to replace the Dunlops and traction is utterly comical by comparison.

I've been able to floor it in second in the wet without the power getting cut.

I had the Dunlops on my 5.0 XKR when I got it, quickly swapped for Vredestein Ultrac Vortis - miles better. Later went for the Michelin PS4S, I'd say the outright grip wasn't that much better than the Vredesteins but feedback was significantly improved, I'd use them again without question. My C63 came on four nearly new Continental Sport Contact 7s, can't compare directly with the Michelins as they were on different cars but they're also very impressive. Any of those three will do you very well.

PS4s all day long. Made the world of difference and they have lasted for ages.

You could fit a pair of £120 Kumhos and they’d knock the spots off those Dunlops, they were ditchfinder level bad on my XJ in the rain, sliding everywhere at walking speed.

When I picked up my XKR Dynamic in Jan, they’d just put a set of Pirelli P Zeros on it. No expense spared by the JLR main dealer.

Probably not what I would have put on, having had them on both the F355 and Mazer, they are a fantastic tyre in the warm and dry but wear quite quickly. But v skittish in the cold. And over early Spring in the SW with single figure temperatures, the car did struggle for grip.

I put Avons on the Mazer 4200 in the end, which I thought were pretty good and very underrated. Hopefully won’t have to think about tyres for 5he XKR this year but will follow with interest.

I've got P Pzero PZ4 on my XJ Supersport and also found them to be quite exciting in the cold, glad it's not just me.

I'd not buy them again, I've found Pirellis to be inconsistent performers for decades like a mid range tyre at a premium price, but I wouldn't throw them in the bin like the Dunlops.
