Towing with a lowered air-ride vehicle
Anyone tow with their lowered air-ride e53?

I am considering lowering my 4.6is with the front springs and rear links, and I'm curious about how it might affect towing ability, specifically tongue weight capacity.

I would be occasionally towing a car (my e36 M3) to the track, and maybe a slightly heavier vehicle at some point.

Also, how does lowering the "truck" with the auto-leveling link mod affect the ride quality during normal driving? I work with vehicles which ride like dogs**t when the air cylinders are leaking down or not filling up all the way.
Is this thing gonna bounce all over the place if it's prevented from fully airing-up the bags?

My iS is lowered about 1" by coding. It tows just fine.
I didn't notice the difference before and after lowering.

Mine is lowered with springs and links. No affect on towing or noticeable ride

Is his a 4.6 or a 4.8?

Biggest change will be that you have changed the overall springrate of the suspension, so cornering and sudden stops will differ.. but by how much is hard to say from a computer.
As long as it isn't going to reduce tongue weight capacity, or sway the trailer, I'm fine.

Will the rear links adequately fool the calibration without doing anything else?
