Dynamic / Adaptive chassis control (DCC / ACC)

still not completely sold on this?? sounds more gimmick than anythign to me..

And for some people it will be.

That is the thing - go back and read the other threads.
Some people swear by it. Some people don't see any different. And in those 'people', I'm only including people who have tried it - because if you haven't tried it then what does your opinion matter?!

Many people make the good point though, why spend $1500 when that can go into a quality after market suspension which will give you better performance. That is somewhat true. So purchasing ACC for the 'sport mode' does seem a little besides the point.
However, purchasing the ACC for the 'comfort mode' does make more sense - especially for those considering the R with 19" wheels (and by some accounts, even the standard 18" wheels due to the fact that the suspension and sway bars in the Golf R are 20% harder than the GTI).

I have not tried it, as a demo car with it was not available to me.

However the standard car I drove on 17s seemed more than capable to me. Firm, but not overly so and cornering was flat and precise. I am not one who complains about harsh ride quality, so I've ordered mine with 18s and no ACC. I certainly don't find the GTI to be particular choppy or harsh over bumps, maybe some people need to harden up and realise it's a performance car. j/k

Personally if I want more performance, then I'll install coil over suspension later on. $1500 will go a long way to a decent set of coil overs.

However if you value ride comfort, and this is a subjective thing, then ACC may be of value to you.

[Corey_R]

Yeah - I had my MKV GTI with 18" wheels and that obviously didn't have ACC. Although it could get a bit choppy on some of the roads in my local area, it was always a pleasure to drive within Brisbane, Goldcoast, Sydney (city) and major highways connecting all of them.

I drove the MK6 with ACC and did feel it made an appreciable difference, but not sure I would pick it if I was on a limited budget and had to sacrifice another option to get it.

But I would imaging that if the suspension and sway bars were 20% firmer, as they are in the R, that ACC could all of a sudden make a lot of sense... just saying

yeah i hear your point...ive read the other threads and its abit hard to judge going by them.. it still would be interesting to see if people with 17's and ACC notice any difference...

[Hoversloth]

I can help you out there. I've got ACC on my new car which I picked up last Friday. I've got 17's and I've done about 400km's so far. Yes, you still can tell the difference between sport and comfort however if I was given the option I wouldn't have paid the money for it. I might change my mind once I put some 19's on it but so far while it is a nice to have, I wouldn't be losing sleep if I didn't have it. (As opposed to not having Bi-xenons, which I would miss greatly if I didn't have them!)

Thanks for the feedback Hoversloth. And yeah - that's what I was getting to - I'd much rather put that $1500 of ACC towards Bi-Xenons or something.

Please update us after you've got the 19" wheels on it!

Wont there be an issue when fitting 19" wheels with ACC?

Reason being that the car will look like its a 4WD (literally - not AWD) and sit high unless you change the springs (shorter).

Do we know that its possible to change springs and not affect the ACC system?

[quakk]

nice work hoversloth.. thanks for the feedback!

Nah - the GTI's 17"x7.5" or 18"x7.5" wheels can be swapped out for third party or 18"x8.5" or 19"x8.5" wheels - with several companies making wheels specifically for the GTI/R32 in this size, such as Oettinger.
On the 18x8.5" width wheels you'd run 235/40R18 and on the 19's you'd run 235/35R19 tyres. You could run 245 width tyres, but then there are reports of rubbing towards full lock etc.

Effectively the rolling circumference difference between the 225/45R17 and 235/35R19 is only 2%

Several of Harding Performance's GTI's have run these 19" Oettinger wheels over the years....

[elisiX]

So the car wont 'look' like its riding really high if you go from 17" to 19" and not change to lowered springs?

[noone]

Normally you would lower the tyre profile when changing the rim size so the rolling diameter does not change (or only by a few %).

Bigger wheels look cool, but less tyre profile means the 1st point of suspension (the air in the tyre) is reduced, making the ride often rougher. If the new rims weigh more, the unsprung weight can change the handling, normally in a negative way, but depends on the rest of the suspension setup.

Are we talking about something different here?

[Sute]

+ 1.

I have the ACC and the 18" combination. Although it will make Sydney's roads fell better when 'confort' setting is selected it's not that noticable on a freeway (IMO). I guess depends on the roads you'll be using the most. I would have been kicking myself now if a heve lost out on the xenons over the ACC. I think the xenons should be the first on your wish list, folowed by 18", leather, ............. ACC somewhere in the bottom half (again IMO).
Good luck

[quakk]

dont get started on the leather!!! another one of those bloody can do-do without issues

[elisiX]

Sorry that's right. I wasnt thinking properly before I replied.

Tyre profile will most likely make up for most of the gap.
