It's all a question of compromise. If you are willing to sacrifice wet grip, wear and NVH for improved dry grip and better response, then the PSC2 is the way to go.

Won't last as long though. Sounds like you'll get 2k km out of them!

I have run all 3 the Ps4 been the quietest and the tyre with the least NVH.
I really don't think there is anything in it between the PSC2 and the PSS.
The SC2 is not bad at all

so far I have been using them as daily drive, once they get up to temp they grip and grip well. I also feel they are so much more progressive and controlled when they slide compared to the ps4.
doing controlled power slides is super easy with this tyre.

NO brainer for me, I will give up a bit of NVH for grip anyday and its not like they howl or are stupid stiff compared to a full on R-Compound.
Lets see how long they last..

Do you know if the difference in diameter of the PSC2 throws off the speedometer or messes with the MDM/Traction Control systems at all?

My '18 F80 came with 265/35/19 (F) and 285/30/20 in the rear PSC2 on M performance wheels.

The tire has great dry grip and as others have mentioned, needs to get warmed up. Has anyone tried running 4s in the rear and PSC2 in the front? I'm burning through the rear PSC2 way too fast (current projection: 2000 miles/replacement) and want something that will last a little longer.

Can't Say about speedo and what the difference is.
I will fire up the Vbox and compare it.

I also have not noticed a difference in MDM, but my car is euro spec so come in with EURO MDM.
I still think Euro MDM is still way to obtrusive, i want to code in GTS as most of the time I ride with DSC off.

in the lower speed stuff it allows a fair bit of slip when you add speed to it, it becomes intrusive, a bit to much for my liking.

ye hard to say, I am not a fan of mixing tires.
so I would not do it, I wouldn't even mix different spec sport cups 2.
maybe over-thinking things

whoop_ass and MPoweRo , how are the 245/35-20 Cup 2 holding up lately on track? i tried the stock 265/30-20 PSS on track recently and i quite liked the way understeering was mostly minimal. i'm still a bit worried if the 245 Cup 2 will pick up a bit more understeering behavior (of course cornering speed is higher with Cup 2 even if there is any understeering).

remarks: understood the tread width is wider for 245 Cup 2 than 265 PSS, but the rear 285 or 295 Cup 2 is also wider than stock 285 PSS

Hitting a track this weekend, with many tight turns
will update
but compared to PS4s you cant even compare the turn in of the P4s to cup 2
car just feels so nimble with the sport cup 2 front.

I don't have a reference point as the PSC2 is all I've had on the car.

What I can say is front end bite is good and the car overall is balanced. I would say a tendency to understeer in high speed corners and power oversteer in lower speed corners. Keep in mind I have GC camber plates with 2.4 deg negative camber. Tyre temperatures were consistent front to back.

I am so far very pleased with my choice.

Cheers.

Ps I should specify that I was at a medium speed circuit (Sandown) - max speed 230kph, highest speed corner 150 entry, lowest 55.

thx whoop_ass and MPoweRo , i'll likely give 245/35-20 Cup 2 a try!

[Bon F80]

MPoweRo , btw what tire pressure were you using?

33psi hot seems about right. It takes about one minute to bring them back up to temp once they've cooled.

They seem to have a reasonably broad operating window and will tolerate up to nearly 40 but the car will be slipping around a bit by then.

thx MPoweRo. i was running the stock 20" PSS on my ZCP with 34psi when cold on track the other day, the front outer edge of the tires was almost gone after 1 track day (too much rollover i believe). hence is 33psi when hot too little? or the sidewall of Cup 2 is much stiffer so rollover is not a problem?

Are you running camber plates? If not then that's what caused the excessive wear of the very soft outer tread blocks of the PSS. PSC2s also need negative camber or they'll end up with excessive wear on the outer tread.

I've found 34 psi hot to work well with PSC2s on my M4 (alignment and suspension setups).

thx M3SQRD, no I'm not running any camber plates at the moment. hopefully with the appropriate tire pressure the problem will not be as significant. will put on KW Clubsport eventually but not at the moment

Tire pressures won't help much with outer tread wear. Staying below a certain hot tire pressure helps to maintain consistent grip levels (i.e., not becoming greasy/sliding around). Only camber will help minimize outer tread wear.

looks like then i'll need the KW Clubsport sooner , thx

Yes and no...

Working with a tire pyrometer, I worked at progressively optimizing my tire pressures. I now run 42psi hot in front and 31psi hot in the rear on my 275-305/35R18 NT01. I now have a much more even temperature distribution across the tread and was able to increase my front tire life from 3~4 days to 5~6 days, almost matching the rear. Before that, I used to cord the outer and inner edges and that is with -2.5deg of front camber.

Let me qualify my original statement...unless you already have camber plates installed, tire pressures won't help much when it comes to minimizing excessive outer tread wear. Optimizing pressure by itself will have a barely noticeable effect on PSC2 (as well as any r-comp) outer tread wear.

SOOO glad i found this thread. Buying new tires for new wheels this week. front are 20x9 et25 and rears are 20x10 et34. Currently sitting on stock suspension, will be going to HAS kit though. Can I run the PSC2 245/35/20 up front and the 295/30/20? Any feed back would be great as I need to get new tires ASAP. If someone could give me the info I need to take to my shop I would really appreciate this. Thanks!
