'Sport' Air Springs into 4.8is?
Hi all.

I've come into acquisition of a rear pair of Arnott Sport Air Springs, and in checking around it appears even with the VIN-specified S221A (4-Corner) and S226A (Sport) suspension packages, all 4.8is models are equipped with 'Comfort' air springs instead. Is switching this a 'no-no?'

1. What is the difference between the two, comfort vs. sport? Does anyone know?
i.e. Height? Diameter? Air capacity?

2. What happens if I put these sport springs in? Am I risking anything "bad" happening?

Following, I'm curious as well.
I've converted my 4.8 to coilovers but have thought about adding the rear bags back on for towing. Put a manual switch on it maybe.

Don't know much, but get COMFORT! The bags provide extra articulation for the adjustable suspension, so sports are no-go.

This - don't go outside the box on this one - you need the Comfort bags from Arnott

CHECK WITH BMW VIN CODE AND YOU WILL SEE YOUR 4.8IS HAVE SPORT SUSPENSION [ALL 4.8IS ].

I believe this exact comment was covered in another thread just a few months ago and is exact opposite of what you're saying.
4.6iS and 4.8iS and NON-Sport models all use the Comfort air bags adn ONLY the SPORT edition models (Yes 4.6 and 4.8iS are excluded from this) are the only models running the Sport air bags.
