'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.

I checked the BMW vin code and it shows I have sport suspension, I have read that 4,8is come with comfort despite being the sport model. I ended up calling the dealer and they ran my vin and conformed the rear air springs are comfort and not sport.

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
