Sounds absurd, but I want to raise it up to an all-road height for about a year or so.

 

I think you'd stand a much better chance at raising it using standard suspension components. Are you talking about incorporating the air suspension into an S4?

Why not chip an allroad, add sway bars and an upgraded exhaust? Sure it'd never handle like an S would, but it'd be a quickand fun 4000 lb ride.

 

Why do you want to raise it up?

 

He's probably gonna torture some poor Cayenne owners.

 

HA! I don't think a Cayanne has mud or branches contact the body....

But really, I might move on top of a mountain in Big Sur, CA and the roads are so steep and rough that I want to raise the s4 up a couple inches temporarily to protect the undercarriage from scrape-age. Coil overs would be great if they could raise the car and lower the car around the stock height.... but all I know is that they lower, and I do not know if they raise.
Does anyone know how to do this?

 

Mabey you should trade it in for an allroad for now.It's going to cost you alot of cash to do the coilovers& alignment when you go up & down on the ride height.

 

thanks

 

get a allroad, you wont regret... and the 6 speeds are almost as fast as the s4s anyway. Chip and exhaust and you wont be dissapointed. Ill have my ar forever. It does everything!
