997.1 GT3 - Track tyres / fast road - what’s recommended

[Mc F]

Considering Nankang CRS or PS4s for a track day.

Any track guys out there with recommendations?

About to replace a worn set of PS4s.

I’m not worried about porsche approved….

I think Cup2s are still the daddy for track days?

I am about to replace a set of old Cup2s on mine with Continental sportcontact 7. They seem to be the latest and greatest test winners, with dry track pace around the Cup2 but with far superior wet performance.

I'm not expecting they will hold up to track sessions as well as a Cup2, but let's see!

AO52s (assuming they do the right size) keep being recommended to me as an all purpose List 1 tyre for races in changeable conditions. No first hand experience but would assume that they would be pretty decent on the road too. The tread looks fairly similar to the CRS you mention and looks more forgiving in wet conditions than something like an AR1 (which I like in the dry) or an AO50.

AO52's or Dunlop Direzzas, the Dunlops are my preference though

Are the Direzzas road legal though?

[blaine54]

Yep. Although they are on my race car so it gets trailered so I can't vouch for road use or ware off track. But they are the best non slick I've used on track 😄

Sorry to derail the thread but how do they compare to a proper slick? I've been using slicks/wets but am now doing a different series where the tyres have to be List 1. Currently using AR1s (which are fine for what they are) but clearly a big step down from a slick (about 1.5s a lap for me)

[blaine54]

Lap time difference is about the same as you with a slick vs grooved. I'm running in a non slick series as well, so a dunlop over a nankang or 888 is about a second a lap at the Snett 300 which is a lot and they are really consistent over a 40min race .

If you want them to be able to cope with wet UK roads as well as decent grip on a trackday then I`d go Michelin Cup 2 or replace with what you have now. I looked at the prices of the CRS and was surprised at how expensive they were.

[blaine54]

When I used Nankangs (pre CRS) they didn't like the cold or wet at all, but good on a warm day. If the compound has stayed the same I can't see them being any different and like you say expensive now

[JayK12]

If you want a road and track tyre I'd check out the Yokohama AD09, A rated in the wet too. I Have a set coming, the Cup2 are coming off.

I’m in Australia so air temps 20+

[blaine54]

Spoilt for choice then really if in Aus with predominantley warm dry weather.

I'd move away from Pirreli's and my order of preference would be Dunlops, AO52's, CSR's (as they can be a budget option that last longer with there hard compound) and then Michelin.

Interested to see what you go for, but I guess also availability will be a factor?

FTFY

Just bunged another set of Cup 2’s on mine, but following this thread with interest. I have definitely not found Cup 2’s lacking in the cold and wet. I think they do far better than even Michelin claim.

However, whilst I am very happy with Cup 2’s, I also have a nagging suspicion some of the newer tyres may have them beat.
