I'm hoping to pop down to Cardiff this weekend for a quick inspection.Noticed my car has Dunlops rather than Michelins,probably better in the wet ,only time will tell
Dunlops are worse in the wet and worse in the cold vs cup 2's. I have not long thrown a set of Dunlops in the bin 1/4 worn as I could not get on with them at all £1400 as well so bloody expensive test :-(Also a shame they are worse on track and Don,t stabilise in psi :-(
And bloody hard side walls so a much worse ride.
At spa last year I could not stop them overheating either so no grip after 2 laps and no grip for the 1st half a lap, so you get one fast lap from them.
And last they take longer to get heat into them from cold so in the winter for road use no grip what so ever, I could even spin the wheels in 3rd gear and the car under steered off roundabouts the 1st 10 miles is like driving on ice when damp and cold.
Cup 2's are an amazing tyre, maybe not as fast for one lap but stable psi and heat up nice and far better in the colder weather.
I could well see people having an off in winter with Dunlops , so if the car does not feel as good as you thought you may have to bite the bullet and throw them away for cup 2's.
I could not not trust the Dunlops for me to push on so as I say I ditched them.
Sorry about the bad news I feel the pain having ditched a set.
Thanks for your thorough opinion on the dunlops
.This is the general concensus on them on all forums.What are your thoughts if i request my OPC puts a good quality winter set on my new GT4 prior to pickup.The last thing i want is to have some lairy slides before i get used to it esp bearing in mind where i live and this time of year

Sorry bit tired when I typed that last night. I miss the last 1500RPM of the 991GT3 rather than the 997 GT3. Performance wise the 997GT3 and the GT4 are overall similar but also quite different. The GT4 seems to be have a more generous torque curve and a very linear delivery by comparison. There is no significant hole in the torque curve on the GT4 but no extra top end excitement either. Perhaps it's just the evolution of engine tuning that has smoothed things out. As a DD the GT4 is better IMHO. I have only got 2000miles on so Its very much first impressions for the top end of the GT4.
As a quality place to sit and while away the hours the GT4 is much nicer than any GT3 I have experience off, 991 included. The interior is lovely, especially the buckets.
Still not totally convinced by the GT4 yet for me. The jury is still out in my head. one thing for definite it is an absolute bargain. Not sure I can buy into the ECOTY result but the Autocar verdict is drivel.

I find my GT4 far more usable, comfortable, and enjoyable than a 997 GT3....But like you, I miss the manic nature of the 991 GT3's engine from 8k rpm onwards..!

Tough choice as I would put pss on but an OPC won't they are not N spec..This is the general concensus on them on all forums.What are your thoughts if i request my OPC puts a good quality winter set on my new GT4 prior to pickup.The last thing i want is to have some lairy slides before i get used to it esp bearing in mind where i live and this time of yearYou could go full winters but I have not seen a matching set from the same make in the right size.

It's not a track day it's an open test session. I have a race license and there are not many cars out so I should be able to sneak out for a bit. Lanan racing who look after some of my cars are testing their new F4 cars so I am hitching a ride with them.
Mind you I may not be going now as the forecast is a bit pants and I don't fancy it much in the wet on cups, so don't rush down.
Forecast is looking better for tomorrow at donington May even get some Sun in the morning.Mind you I may not be going now as the forecast is a bit pants and I don't fancy it much in the wet on cups, so don't rush down.

That's a pretty scathing review. It is hard to understand how they are factory fitted if they are this bad.Also a shame they are worse on track and Don,t stabilise in psi :-(

As I said the Dunlops will give you a faster lap if you time it right.
As for wet use Cup2's are far safer than Dunlops. (people get mixed up with race maxx and sport maxx) I only talk about race maxx, I think the GT3 winter tyres was a sport maxx !
Small reviews in hot temps is pointless, I lived with both these tyres for 1000's of miles though summer and winter and on track.
IF you want the fastest UK track road legal tyre you buy a Pirelli trofeo, but life on them is bad ie very bad.
Shame we cannot buy nitto's track tyres they seen the ones to get the fast lap in the USA.

After doing some research on Rennlist and 6speedline forums i've found more favourable opinions on Dunlops vs Michelin.Sportauto supertest tested them back to back and found the Dunlops quicker arond Hockenheim.Also i seem to remember last year reading APOLLO 1 comparing Michelin cup2's and Dunlop Maxx Race on his GT3's and concluded that the Dunlop's were more suited for UK driving in wet conditions.Autocar recent comparison criticized MPSC2 wet performance.If you're reading this Apollo could you recap your experience with both tyres.
HiDone over 40 track v-max events in my RHD and LHD 991GT3s, RHD had Cup2s, LHD had DRMAX,
RHD, Cup 2s
Take a few dial downs to get right on track then they work fine, don't like temps below 10d, and don't like a wet road or track, but when warm and at the right temp they are fine, good wear rate also.
LHD DRMAX
Again take a few dial downs to get right then offer about the same grip level in the dry as the Cup2s, but in the wet or temps below 10d, imv they offer much more grip on road and track. They both seem to wear about the same also.
991RS. New Cup 2S
Now done a couple of track days, the grip level and wet weather performance from these tyres is like nothing I have ever experienced on a road car before, they inspire so much confidence to just press on, but they need to be set at the correct pressure, the ones above does not matter so much, couple of PSI either side, but the ones on the RS need to be at an exact 29-33, big difference in braking performance outside this...

Thanks Apolo for your quick succinct reply.This tallies with some observations from experienced trackers in europe and stateside.The general consensus is the huge variation in official wear rates between MPSC2 and DRM respectively 180 vs 80 where Pirellli Trofeo r is 60.Apparently both these tyres need 3-4psi difference in tyre pressures for optimal track performance,can't remember which wayDone over 40 track v-max events in my RHD and LHD 991GT3s, RHD had Cup2s, LHD had DRMAX,

.I'm down to Cardiff tomorrow to pick up my GT4 so hopefully will post some first impressions if i can drag myself out of the LWBS

My pick up tomorrow . White clubsport on Dunlops. Snow forecast up North tomorrow so should be fun .....
Given Demon's damning report on the Dunlop DitchMaxx's, and the danger of inattentive police leaving you to die in the first snowy ditch, you might want to consider picking up another day ;>Have just returned home with my new GT4.First impressions are all positive from the moment Ian teased me by just pulling the cover partly off.It looks amazing in guards red with PCCB's and platinum alloys,much better than i expected
On the drive home about 100miles half on motorway and half on twisty backroads have some impressions.
Wonderful supportive LWBS esp with height control for the family and teutonic build.Much nicer noise than expected and not at all contrived like the boxster GTS i drove last year.The PCCB's are otherworldy in how they wipe speed off with seemingly no effort,also much better brake feel than expected.Although not pushing very hard on the wet greasy twisty backroads pleased with the dunlop's so far and gained confidence just before getting home.Can,t wait to get it on a track next spring,should be a complete hoot
