Hey folks,

I took my bone stock C2S 7MT out to track at Ridge Motorsports Park in Shelton, WA last weekend. It was a blast! I have been ripping the track every single session and managed a fastest lap of 1:53.5, which was amazing considering it was only my first day with C2S and still playing around with tire pressure settings.

However, as it gets later in the afternoon, my tires overheating and understeeting issue got worse, and I found out the inner side of my tires were pretty used up. (After 7 full 20 mins session without any tire management). I was really surprised with how short life these street tires have, even with overheating.

Now I have to find a replacement for my next few upcoming track days this summer. I am debating Pilot Sport Cup2 / Pirelli Trofeo R / Dunlop Sport Max in 245/305 to fit on my stock rims. I daily my car and put down decent miles and plan to use this set of tires over the summer. I'm wondering what would you guys choose? Any suggestions? anyone knows all of their tread wear ratings?

Thanks in advance,
G.

I have the Michelin Pilot Super Sports on my stock wheels and they work great, as long as you keep the pressures below 40 psi. I find that if I start with 28/30 colds, that works out well. I am sure the R compound tires above are stickier (Sport Cup and Trofeo), but you would likely want t separate set of wheels as those tires would not be good daily drivers.

+1... I will add that sport cups (any r compound tire) can be rather nasty if you are not a seasoned tracker. Tons and tons of grip until you have none - without warning, no sound. So I'd run a dedicated track tire only after you are well into the advanced class. And as mentioned above, they suck as a dd... especially in the rain.

Forget lap times. Run street tires until you are driving the line with precision and consistency and have your tire pressures down pat. Until you reach this point don't go out without an instructor more than one session per track day. Being in Bellevue you should also sign up with PNWR for Driver Skills out at Bremerton, and DE at PR. But the Driver Skills is by far the more valuable one to take. Not the advice you were looking for. But I will guarantee that if you do this then by the end of the year you will look back and realize what I already know, that you were overdriving the crap out of your tires and could have been going a hell of a lot faster without all the wear and tear if only you had the skills.... which if you follow this advice you will have by then.

Below article provides a bit more insight into what Chuck911 is talking about.

Oh yeah, Silverstone!
I'm getting a little woozy just thinking of it, like Jeremy Clarkson saying "silicon carbide". There's a ton of info in that short article. Like the way the writer was thrashing his tires by creating understeer going too fast using too much throttle. Or the way he learned its better to sit back with shoulders well into the seat for greater car feel and control. Or all the time he wasted working on his performance of a mindless task now thankfully rendered obsolete by PDK.

Anyway, I just realized the OP may not know about PCA or PNWR and since he can't be PM'd... http://www.pnwr.org/

Its been a while since I was running Driver Skills but I know the program and cannot recommend it highly enough. There are also several National level autocross champions in PNWR, and you can learn a lot from the autocross instructors as well.

In 19", I like RE11 & AD08. For the 20", tough luck in choices.

I'd forget about the Sport Cups for a daily driver. You just won't get that much life out of them, I've heard of 997 GT3s barely managing 3K miles out of a set.

I'd take a serious look at Dunlop Direzza Sports if they have them in your size and the Pilot Super Sports which is what I'm personally planning to replace the stock tires with on a 981 CS. I've driven both on my previous BMWs and both were very good in wet and dry conditions (the PSSes were particularly amazing in the wet). I didn't get a chance to track the PSSes though.

PS
I was at the same track day in the Spec Miata

+1 for Yoko AD08s. Just did a day at Watkins Glen with them in 19"--did very very well. 255/35-19 front and 305/30-19 rear AD08R.

Yes you did if you are the blue 991 I talked to. I will give them serious thought when I get track sets.

paradocs98

That was me. Great to meet you.

You can get Nitto NT05 in our 20" sizes.
They cost 1/2 what PSS cost, so you can tear them up on track with no worries.

Ill buy 1 front tire for you, to see a review ; )

I have PSS and they got greasy fast.

John's 991

Lunarx, I did not think the Nitto's were available in 245/35/20 and 295/30/20 sizes. Did they release recently? I would be interested in trying them.

I am using the MPSS now, and like them much better than the P0's, although you do have to keep them under 40 psi to keep them from getting slippery. I find that this works out to a 28/30 cold temp, if that helps.

lunarx

Well you are right, they are not available in those sizes.
However, they do have 255-35-20 & 305-30-20.
I put those size PSS on my Sport Techno Wheels.
Those sizes will fit on the standard wheels too.
If you try them, I really want to hear what you think.

Anyone try Toyo T1R's? Had them on a Nismo and they worked pretty well.
