The upshot is that I thought the MK6 without the switchable dampers both handled and rode better than the MK5....just slightly.
How old is your Mk5? Maybe your suspension is nicely 'worn in', whereas the demo Mk6 will still have tight suspension. A similar thing occured when some peeps swiched from the std Mk5 GTI to a newer Ed30 - they innocently thought it had different to the std GTI - when they are in fact identical.
It maybe that i agree with you i have the same feeling going from our high milage company GTI mk5 to my own low miles one.
Are you saying the mk5 GTI and the mk6 GTI are identical?
Yes, well within the usual weight-range differences. The Mk5 and Mk6 have identical front and rear subframes, identical suspension arms and wishbones - which will all indicate identical geometery (again within the usual range of adjustments). The actuall spring rates also
appear to be identical, as do the dampers. The only real difference is if you spec the ACC, or whatever its called - which substitutes the conventional 'analogue' dampers for the electronically controlled dampers. These are exactly the same as the Audi TT.
or simply tacking onto the end of that that the ed30 and GTI mk5s are identical?
An that too.
If so may i ask have you checked up that the mk5 and mk6 GTI suspension are identical with identical components and use exactly the same rates?
The 'hardware' (apart from the optional elec dampers) are identical. The rates are more difficult - all I can say is that the full range of springs and dampers available for the Mk5 (variable due to the 'kerb weights') are the same offerings for the Mk6. But weather say a Mk6 GTI with a kerb weight of say 1435 kgs has exactly the same rates as a Mk5 of 1435 - that I don't know.

I thought i read in a VW press release from germany they had changed something but cannot remember what for sure now it maybe was the rear antiroll bar? but i cannot remember for sure.
Hmmmm . . . I don't always take 'press releases' as 'gospel'. Even some of the official 'Technical Data Sheets' get things wrong - the gear ratios for the DSG gearbox are a classic example!

But maybe they have increased spring and damper rates, along with beefier ARBs - and the ARBs are something I haven't checked! :embarassed:
