I seem to recall there being some issues with DBS models suffering wheel wobble/vibration. Has this ever been resolved by AM? Is it just a problem with the actual wheels themselves or something more sinister?
Finally, does it affect other V12 models, such as V12 Vantage, DB9, Virage, etc?
Thanks

It's not the wheels, it's the CCM rotors. And it can be fixed via a Rube Goldbergish wheel balancing procedure.Finally, does it affect other V12 models, such as V12 Vantage, DB9, Virage, etc?

Any dealer with access to a wheel balancing machine that can do a bare rim balance (for the CCM) can do it. There is a service bulletin with the procedure laid out in it.
I still cannot understand why this is not done at the factory when the cars are built. Half an hour and the problem wouldn't be there.

I'm genuinely shocked. I recall this being such a massive issue a few years ago, and to think, it is resolved by 1/2hr with the right wheel balance technique.
Don't understand why Aston can't properly deal with it. Porsche, Ferrari, Lambo, Audi etc have been using Ceramics for years with no such problems...

Blimey. Where does one go to get the wheels balanced in this way?
I suppose the other alternative is to rip off the CCM's and whack some steel brembo's on... keep the CCM's in a box until resale and then pop them back on....
The true petrol head would rather you leave the steels on I suppose the other alternative is to rip off the CCM's and whack some steel brembo's on... keep the CCM's in a box until resale and then pop them back on....

Go ask the Corvette ZR1 owners about CCM balance issues...same as Aston.Don't understand why Aston can't properly deal with it. Porsche, Ferrari, Lambo, Audi etc have been using Ceramics for years with no such problems...
I think this problem has all but disappeared with better rotor balancing at Brembo. You certainly don't hear of it very much any more. And I would imagine that older cars that suffered from this from the outset were corrected post-delivery.

I have a client who runs GT2's and GT3's (although I guess his 2 new ones are still at the dealers making sure they don't catch fire) at the 'ring giving his customers rides
Always specs steels now. No loss of performance and a little cheaper 
Also has a 430 Scud and says its useless around the 'ring: reason - brakes not up to the job.
He also has a 458 Spyder but that's just for going to work so it doesn't really matter

Contrary to all accounts, you'd really rather have steel rotors rather than your CCMs for track use? I understand that the steelies are much cheaper, but surely the CCMs will last longer and will resist fade better than any equivalent metal version.
Having done the B500 in Germany driving in a spirited fashion with steel discs I can say without hesitation that they fade after 45 minutes of very hard driving. Happened to a couple of us at least, and I suspect those with CCMs didn't suffer any fade at all. I can't imagine how much worse driving hard on track would be but I cannot believe that steel discs would outperform CCMs.V12woollie said:

Mine were ok on the D500 but I drive like a girl anyway 
However I have heard the same about track day 'professionals' liking steels instead of CCM's
Fast road driving, CCM everytime for me. No fade, no dust absolutely superb.
Track driving, shed loads of dust and wear on the pads and the CCM's get very roughed up also (unless you drive like a girl
lotto 
). Don't get me wrong, hard driving around SPA (not sure I mentioned going there) and the CCM's never had any fade, no matter how hard I tried. The issue is that the cost to replace discs and pads after a trackday will leave your wallet severely dented. 15,000 miles 2 sets of front pads and the 2nd set lasting only 4,500 miles says it all
Trackday cars need properly specced steel discs and proper pads, fast road definitely the CCM's.
OP the wheel wobble has been correctly diagnosed by the pie eating one

Having munched through rear pads in 5000 miles I have never experienced brake fade in our V8S. Even howling down Alpine passes I never had a cause for concern. Most of the wear occurs whilst taking bends . This probably accounts why some Indies choose to fit V8S discs and calipers as part of an upgrade.
CCM discs have huge advantages over a steel set up . The reality is that in a World outside of a race track you will never know. Could it all be a dick waving exercise? Spec your new F. Type with CCM brakes , £7500 to you Sir. Will you ever need them ? I doubt it.
