Finally got around to weighing the new BBS wheels while I was cleaning and ceramic coating them before mounting the tires. FYI, when ceramic coating new wheels make sure to tape off about 1" on the barrel right behind the spokes and 1" on the outer part of the barrel. This is so the wheel weights have a chance of adhering to the barrel as the ceramic coating can prevent the weights from sticking properly and then they'll come off.

A bit of warning to folks with cars north of 100k. I just turned over 130k and the crank pulley started wobbling pretty bad, immediately took it to the shop and had it replaced. I was lucky to have caught it in time as it damn near fell off. Another CLS55 was there for the exact same thing but they were not as lucky and the pulley did come off and damaged the front of the block.
While it was up there I had the original coils all replaced along with an oil change and brake fluid flush.
Not much else new other than it has been an absolute time saver on roadtrips especially when the speed limit is already 80 mph
I also had it replaced a while ago. Please note that a small amount of wobble is normal with (very) low rpms. I got paranoid and also got it replaced for peace of mind, and the new one showed the same amount of wobble with low rpm
Really annoying that I can't update my top post but here is the recent maintenance done 8/20/25:
Spark plugs changed
Left and right valve cover gaskets replaced
Left and right rear shocks replaced
Front left and right control arms replaced
Front supercharger and drive belts replaced
Front left and right end links replaced
Ignition coil #3 wiring repaired
And bonus picture of the BBS wheels I got last year:
