how do the Dunlops fare against the Cup 2's ?
Car is a 991 GT3
currently 90% road vs Track, though that will change in spring 2020
only had Cup 2s previously, but there appears to be a stock shortage...
My advice would be to wait and get the Michelin cups. I’ve got Dunlops, and whilst in the dry they’re ok, in the cold and wet they are shockingly bad. Just do a braking test on a wet road from >70mph, and it’s alarming how early they lock up.Car is a 991 GT3

There’s a very good reason why you’ll only ever see Porsche GT press cars wearing Michelins.

I'm glad someone else has made a positive contribution..I wasn't aware that your new RS came with Dunlops. Mine's on Cup 2s which is astonishing as all my previous Porsche GTs were on Dunlops !..The Dunlops seemed OK until i drove the RS on Cup 2s..The Cup 2s are much more confidence inspiring when its both cold and wet where the Dunlops gives no confidence or feel whatsoever in those conditions.There’s a very good reason why you’ll only ever see Porsche GT press cars wearing Michelins.
Still might fit some MP4Ss though as i found them astonishing when i took the 458 to Swindon recently in biblical conditions.

Keep me in touch,i will change the 2.8rsr 5th gear this winter,for some cruising
It’s a very fair point - I need to earn my stripes before I’m allowed out out of the county Keep me in touch,i will change the 2.8rsr 5th gear this winter,for some cruising

It is a fair point. Last track day of the year for us next Saturday...Llandow, tiny track but good fun. Fancy that ?.
Would love to but that weekend I’m “Home alone” in charge of all things young and obnoxious - I know it looks like I keep ducking the invites, but I promise to get to Wales soon enough RSVP911 said:

Likewise I found the Dunlops on road had a better grip in the low temps over Cups, also a better in wet conditions. Agree above that they do lack the feel that Cups give though.

Interesting, as I find the latest iteration of the Michelin cup is way superior in cold and damp conditions to a Dunlop Sport Maxx.Edited by APOLO1 on Sunday 1st December 09:06
Worth noting that the Michelin cup tyre has improved massively over the years. Remember when they were launched on the E46 M3 CSL, and they were great in the dry, but were horrendous even if it became damp. Even back in 2013 when it was fitted on the 991.1GT3, it wasn’t great in the wet. But the latest iteration is miraculous in the way it can generate grip in the wet. I’ve got them fitted to a Golf TCR, and in damp conditions just hovering above zero degrees, I’m still astounded how they can find the grip they do.
If Porsche’s press dept really believed the Dunlop was the better tyre for road use at this time of year then we see them fitted to all the press cars - but we don’t, they fit Michelins, because it’s the better tyre.
Incidentally, has anyone tried a Pirelli Pzero Corsa system tyre on a RWD or FWD car..?

I had P-Zero Corsa as OEM on all my 991.Turbo S, 13-17Ys thought that they were a great road tyre even in low temps and damp conditions. But when used on track in the Turbo-S after 30 Mins or so of fast laps, even with regular dial downs not good they would just go off, no doubt the weight of the Turbo S did not help. Back in 17 the only approved Performance tyre for the Turbo S was the D- Race Max. My Opinion of these over 20k road and track miles is as above.Worth noting that the Michelin cup tyre has improved massively over the years.

I agree that latest version of the Cup 2S That came out first on the Sep 17 GT3.2? are a good step up in terms of both track and road performance over the ones the ones that came with the likes of 15 Y 991.1 RS. The latest version that came on my 19-Y 991.3 RS are brilliant on track, 2 dial downs and they remain stable all day, the wear rate over 400 track miles seems very impressive also. But for me based on my own experience whist I would never put a set on the likes of a GT3-RS etc the Race Max do offer a small advantage in terms of road use in Wet weather and low Temp, like single Figs performance. If I was looking better performance for road driving this time of year, I would do like what the Press team did on the GT3 Touring test cars and just fit proper winter tyres and be done with it.

But of course !. D5 Pirelli Corsa's....wear well and superb in the wet

Agree with APOLLO , Dunlops better in cold and wet ( drove through a biblical rainstorm on way to Le Mans at unabated speed ) and used them all winter last year .
But on track they just get hot and need adjustment , then the rears go off and get wheelspin in the corners even with TC on.
The Cup 2 were much better on track especially the first two days and the last 3 track days the understeer is back , but maybe need to deal with set up as still stock .
This was all on GT3 RS over 8 k miles and 4-5 track days on each type . Yet to use the Cup 2's through a winter though .

I'm familiar with the P-Zero and Corsa, have had them on various cars, but the P-Zero Corsa System is a new tyre, details below. Interested to hear if anyone has tried this exact tyre..?

For those that didn't like the Dunlops, did you try the N1 version or the original N0?
I had the NOs on my GT4 and NIs on the gen 2 GT3..I did 4k miles in the GT4 and nearly 3k in the GT3..In my admittedly novice hands i thought the NOs were better in the wet compared to the N1s and conversely in the dry..As i previously said the Dunlops need 33/35psi F/R to perform at their best whereas the Cups are better with lower pressures IMO..The Dunlops are still very good tyres although most seem to prefer the Cups..

For road use theres nothing in it.
Any slight advantage the Dunlops have in the wet is lost in less durability compared to the Michelins imo.
You are talking about the first gen that were indeed sAny slight advantage the Dunlops have in the wet is lost in less durability compared to the Michelins imo.
t. These second gen tires are much better than the cup 2. They grip better on wet road, they do similar tipes to the cup 2, they cord less, and most importantly, they perform very similar to the end of it's life and aren't as close to be daisys about operating temperatures and heat cycling as the michelins. Right now they are a no brainer for whoever has a gt car. The only minus they have is when new vs new cup 2 are marginely faster.luigisayshello said:

My Instructor at the PEC yesterday told me preferred the latest Dunlops compared to the Cups..He races the GT4 Clubsport and seemed to know what he's talking about..I think the reason most people like Michelins(including myself) is that they seem to be easier to get heat into them when driving normally whereas the Dunlops need to be driven harder to heat up.t.

I was there Monday, went out in the RS on Cups came back in after a few laps, it was 5d. Reminded me that Cup 2s are not really a good road tyre in less than 8/10ds.

I wasn't allowed to take the RS on the new circuit yesterday morning as they said the newer surface on very cold temps and an RS with Cups are too dangerous..I drove my RS yesterday from the first time in freezing temps and you just need to take it steady especially under braking..When i got to the main roundabout by the main Silverstone entrance a hatchback has side swiped a lovely Black M series BMW..Its other idiot drivers you need to keep an eye out for when its freezing and if you need to take quick evasive action then the Cups are a liability..Gassing Station | 911/Carrera GT | Top of Page | What's New | My Stuff
