DBS Steering Wheel wobble
Discussion
No, this is not normal, however DBS is very sensitive to each steering/suspension component. I spent long months and big money on my DBS to remove steering wheel vibration. I started with wheels balancing using Hunter balancer, then I changed tires to new ones, then I replaced tires again to a new brand as the previous ones were “unstable”, then I replaced front alloys. I have finally managed to get a perfect car with stable steering and braking with no vibrations at the full speed range. Each step improved the car, however the biggest one was to replace tires.

What tires did you use in the end? P-zeros AMS spec? I had my car in and the dealer performed the wheel vibrations SB car was reururend with an unbelievable amout of vibration and rattling noise from left disc when braking. A aston martin service team was in the city and they did the SB agin. There was imbalance on the discs. I dont know by how much. It is better on the vibrations but the wheel still wobbles and still rattling. When the dealer performed the sb they put the weights wrong which created a lot of imbalance. Dont know what they did when they removed the discs as now it rattles.
They are saying I need to replace the front discs to solve the issue.
In my case I had two sources of the steering wheel vibrations: wheels and brakes. In my previous reply I focused only on wheels as I understood this is your case, however my DBS suffered from the brake rotors as well. At the end of the day, front rotors have been replaced (one of them lost its balance after it lost a bolt between the CCM and the bell).
I wonder how your rotors are compromised/imbalanced assuming there is no physical damage? What is your MY? Only if you have first generation CCM, then you need to balance rotors and wheels on your car (e.g. using Hunter tool). I know AM has reversed by mistake marks on a few rotors, so you need to move the rotor by 180 degrees to balance properly.
I have changed tires to Michelin Sport 4. Will never change to any other brand.

I have MY 2010 DBS volante, I believe mine are the first gen of CCMs. The issue lies with the previous owner that changed tieres to P-zeros that are NO standard and not AMS. And then the wheels were balanced whithout takeing in to acount the rotor imbalance. I wonder how your rotors are compromised/imbalanced assuming there is no physical damage? What is your MY?

The balanceing was now done by the engineer who wrote the wheel vibration SB but the wheel wobbles are still there. It is now in a worse condition than it was before I left it at the dealer to fix it in the first place.
Michelin sports 4s will be the next tiers I get then
Thx for the info.
I swapped to Michelin from brand new Pirelli P-Zero AMS, which did have vertical (radiative) vibrations. Fortunately, Pirelli accepted my complain and refunded fully. With Michelin no issue after 10kkm.
I think you need to balance your wheels put on the car together with the rotors to fully compensate rotors imbalance or to do two-step Hunter balancing as per the service bulletin SB-04-0318. Below please find VINs and rotors generations from service action document SA-06-0189.
E00001 to E02521 Discs not balanced - No paint marks unless SB-04-0318 is done.
E02522 to E02603 Discs correctly marked with the paint mark at the highest imbalance position.
E02604 to E02668 Discs incorrectly marked with the paint mark at the lowest imbalance position.
E02669 and after Discs are already balance at manufacture - No paint marks.

I recently had to replace the front rotors on my ‘12 Virage with rotors off an older DBS. BTW the Virage rotors needed replacement due to corrosion and failure of the bell/hub bolts. Anyway the DBS discs have distinct paint marks on them. I now have high speed balance problems where non existed before. Based on the helpful notes about the painted marks should I mount my wheels with the balancing weights opposite the rotor marks or in some other position? The tires are very new Michelin Pilot Sports so the wheels have recently been balanced.
Thanks!
Thanks!
I assume your “the new” rotors part number starts with “8D33”. Then, you need to use Hunter tool to check imbalance point and weight on the rotors, and then add the weight on your wheels at a respective points to balance fully the rotors. Alternatively you can balance the wheels with rotors together using "wheels on the car" method. Good luck. The exercise is very annoying, it took me weeks to balance my rotors. Colored marks can be misleading as there were some parts produced by Brembo for AM wrongly marked.

where to look for the VINs and rotor generation ? on the rotor?
