Hello guys.
Drove an R the other day without Adaptive Chasis Control and was surprised to see you still get Race Mode in the driving profiles and the suspension in race mode wasn't harsh at all.
After speccing this on my GTI I've never felt any difference in any suspension setting (maybe very slight when being pushed) and ive asked all my passengers if they feel any difference while I switch modes, to which they say "no" so...
Adaptive Chasis Control, a bit crap for £815? I'd say so...will not be speccing this again.
Was the R you drove on 18s or 19s? What size wheels on your current GTI? If you're on 18s perhaps that's why you don't feel the need to make use of it, as arguably they give the optimum ride and as you say, the standard setup is pretty good anyway.
Now I haven't tried the DCC (formerly ACC) on mk7, but if you have 19s maybe that's where it becomes a worthwhile option, as we know they give a harder ride, whatever the car. I have ACC (albeit on a mk6) so the poorer cousin, but even that takes a slight edge off the harsh ride on the bigger wheels. By all accounts the 2nd generation on the 7 is a different beast, a distinct improvement with greater adaptability so reason enough to spec it if you are going for 19s?
I have specced it again on my R primarily as I'm sticking with 19" wheels, and, if they come on the woefully hard Bridgestones, coupled with our crappy UK roads, I might be even more thankful for it

(not that they're likely to stay on for long)
