Amazing drop off after the first lap on the RS. Expensive game chasing lap times on track days! Will be interesting to see a head to head against the Michelin equivalents

Apparently they will make them in GT3 fitment too, but only in the R (not faster RS). Hopefully, having three OEM approved tires will cause a little price competition...

I understand the market these serve as an arrive-and-drive tire, but if one has the means to get another set of tires and wheels to the track in a support vehicle, then going to a full slick like the Pirelli DH or DH2 will give better performance, last longer, and actually cost about 30% less.

And since I have a Non-RS, it seems like Cup R and Goodyear RS won’t even come in my sizes

4 second faster is a lot. I wonder if the gap was created by the drivers comfort level with the car after few drives. Great to have more tire options and wonder how they compare to cup 2

I’m not sure what the risk actually is, but Porsche can theoretically cancel your warranty if running slicks (and they can show some causation between that and an engine or suspension failure). The Cup R and Goodyear RS seem comparable to Hoosiers, but OEM approved. Real slicks are faster still, I’m sure. Since I have to drive to the track, real slicks (and possibly even Hoosiers) are not going to work for me.

Are we talking bushings or something else?

I have tested two sets of the Cup 2 R. Great tire for 2, 20 minute sessions then a rapid drop off. Approximately 1 second slower each session thereafter. I have switched to Hoosiers on 19 inch Forgelines as they are half the price.

Good info, thanks for the real world data. The R is definitely a cheater tire but it doesn't seem to have the value over the long run.

Regarding what the question is with slicks, I think the first place you would see issues would be in the wheel bearings other than that I don't think there's too many other components that would be impacted.
On my 944 LS3 swap I'm running 315 and 330 Hoosiers and I basically need to change wheelbearings once a year the rest of the components are fine.

Porsche already documented "Not to use slicks" in the 991.1 GT3, some issues related to the Rear Axle Steering. The link to the official comm is buried somewhere here in RL.
Run slicks at your own risk.
