Is there somewhere else other than the stealership I can get the rear air bags for a P030 package E63? I don't want to use the Arnott's as you lose the ADS function. Everything I have found says "without performance package".

You only lose the ADS function if you go with the NEW shocks/bags from them. If you go with a REMAN they keep the ADS as noted by a post from Arnott not to long ago in this forum.

Arnott's A-2725 Rear Air Spring for the 03-09 E-Class W211 and 05-11 CLS-Class W219 AMG (with AIRMATIC & ADS) will work perfectly. These install up to 90% faster than the OE because you don't have to drop the sub frame like they must at the dealership.

Doesn't it end up stiffer because of less air volume? I'm looking at my options carefully. It's time for preemptive maintenance in the rear.

I don't follow you. So how does less air volume equate to stiffer.

another question to Arnott...the site says "eliminates the OE reservoir". Question: Whats the purpose of the OE reservoir, that its ok to no longer have it?

Sport 1 and sport 2 close valves to reduce the volume of air that compresses when you hit a bump. Comfort mode extends the air volume all the way out to a separate reservoir. The smaller the air volume, the more the pressure increases as the air spring gets compressed. I think there is also a fluid control valve in the shock that makes them too complicated for aftermarket companies to build.

Thanks for the explanation

Good information, thanks.
