Disclaimer: I'm not seriously looking to do this, just curious if anyone else has looked into it as it might be something I'd like to do when my original shocks are due for replacement. I love the idea of having it ride like a '72 Caddy for my commute and pumping it up to eliminate body roll on the weekends.
I opted not to go for the PP+DCC when I bought my car, partly to keep the cost of the car reasonable (paying near-as-makes-no-difference-to-30k for a GTI was painful enough), partly because I needed to get a new car somewhat quickly and ordering wasn't an option, and partly because my car is merely a commuter that is going to ferry my dog and I around the DC area for the next 5+ years, so as cool as it would be to have a diff and big front brakes, I'm not going to miss them 99.9% of the time I'm in the car.
However, being in the DC area, the roads are not the greatest. If the DCC had been available apart from the PP I would've tried to get it.
I know there are aftermarket coilover setups that offer electronically adjustable dampening. There's the KW DCCs which are $3k+ I think, and the Bilstein B16s (?) which are about $2k+. However I don't need any ride height adjustability. Like I said, this car is a commuter that gets used year round in the DC area, I need ground clearance for snow and poorly designed shopping centers and driveways with ridiculous entry angles. My other car has 3 inches of clearance from the front lip and I scrape it nearly every time I drive it.
Does anyone know if you can purchase just adjustable dampeners outside of a coilover kit that could be used with the factory springs? I'm assuming it would be impossible or just too much of a pain to try and integrate them with the factory DCC settings, but that's fine, I wouldn't mind tucking a control panel into the center cubby.
I also wonder if the cars are prewired for the OEM DCC option so that you could simply install them, plug them in and then turn on the settings in VAG COM.
