Techart lowering module compatibility?
 

I was scouting eBay and other places for the techart lowering modules, it seems all the ones I find are for the 955 04-07 models and might not work on my 08 turbo. Now I was wondering did the air suspension change in 08? It seems all the other lowering modules say they work from 04-10? Has anyone tried a early 955 on their 957?
