Good stuff Guy interesting to see this when its completed with times

Guy_H,

Re: Disabling of the ACC (DCC)

Was the steering wheel resistence defaulted to normal mode after you guys disabled the Adaptive Chassis Control when installing the coilovers on the Golf R?

Cheers
WJ

From what we can gather with diagnostics it does not change - you can see dedicated channels going OUT from the steering controller to the ESP system (chassis control piggybacks off this) but there are no return INPUT channels to the the steering. So from what I gather, the only change you will feel in steering is from the dampers being stiffer or softer. It may be elsewhere in the system, but I can't see any reference to it what so ever.

A 135i would be worth the extra if the budget allows it but can't argue with the R for value.

Any more updates Guy, how'd the exhaust go? Did you leave the stock back box and flapper in the setup?

Assume it would sound more like an S3 without it.

Prototype exhaust is awesome - no drone, nice note (a little different to the S3 system). Had to try a couple of configurations internally on the rear muffler to get flow / noise, but this will be pretty close for production!

Will try to get some pics soon.

[Guy_H]

oh, binned the vacuum flap

Is there going to be a RSC version in the future??

Hmmm. There is quite a big difference in steering weight between the Comfort/Normal and Sport mode with the ACC. I'd be surprised if it was simply due to damper changes, especially at speed. So reading about your findings is a bit of a surprise.

Can you explain what the vacuum flap was for? I've seen people talk about the "flap mod" on the stock exhaust, but haven't really found what it's for and the benefits/negatives of having it

Only when Corsa (and the US) get the Golf R unfortunately! Can't be done outside their facility.

I would love to seean actual test on what changes, before we stripped it all out I did a lot of driving & cornering in all modes - I was not looking at the steering, but certainly I did not feel any change what so ever - maybe it's just me!

The Flapper is there to allow different noise at different RPM (helps them pass noise ADR's in some models as the noise test is carried out at a percentage of full throttle) . When we got it we connected & disconnected it - couldn't hear / see much difference, but again I have $10 ears

[Corey_R]

Thanks for the info Guy.
I have crap upper body strength, so I immediately noticed the difference with the ACC and steering in sport mode and came on here to find WhiteJames's posts and then started seeing the feature discussed in most reviews were the reviewer had an ACC equiped car. Now I'm interested in finding out what is being done to the steering when that sport button is pressed

I'm keen to keep the GTI for the RSC and new engine, no fuel pump upgrade requirement is nice.

Re ACC: the steering is much heavier in sports mode, which is great for spirited driving over 80km/h (but too heavy for normal driving and parking speeds).

I can notice a good difference in dampening between the modes but may feel similar if you're used to track setups.

Re ACC: the steering is much heavier in sports mode, which is great for spirited driving over 80km/h (but too heavy for normal driving and parking speeds).

That's actually how I first noticed it. I drove out of the dealer in sports mode and on that mode for about 5 minutes. I was thinking to myself how heavy the steering was compared to my Polo. But then I changed it to Comfort, and went to turn into a side street, and all of a sudden I almost turned the wheel around 3 times it was so light! hehe

Welcome to the girly arms club LOL. My excuse is never getting of the couch to do anything useful

Attach a weight to the remote and within months you'll notice a difference.

On my non-ACC car, I've noticed that the steering weighting is quite speed sensitive. While there may be minor adjustments to the weighting at low speeds, it seems to make a big transition around the 80km/h mark - I've noticed it several times while having a go on faster flowing bends, and also whilst changing lanes at varying (higher) speeds.

It'd be interesting to know how much variation there is in the system on an ACC equipped car in various modes, versus a non-ACC car.

[G-rig]

I assumed that the steering on non-ACC cars would be too light at higher speeds, however maybe having a lower car helps this?
