Going by previous experiences on all variants of the Dunlop ShyteMaxx, I would avoid. There are much better boots available. The difference between the original ShyteMaxx and some Mich PS2s is literally night and day!
IIRC, I think PhilMcavity has the SportMaxx TTs, but I don't think he is particularly 'hard' on his tyres, and from chatting to him at Inters, seems happy with them, but if you are a 'hard' or demanding user, I would still avoid.
I have also tried their so-called top-spec - the SportMaxx GT - on the new RS6 - and they really were NOT up to the job. But bear in mind the RS6 is a 3rd of a tonne heavier than the GTI, and has mooohassive front discs with 8-pot Brembos!
Mich PS2 gets my vote any day! Even on my mighty RS4, they are well up to the job!
