That test though is pretty much is accurate with what I've experienced with GY SC3 vs GY SC3R vs Pilot Sport Cup2 on my GT3RS. GY SC3 < Pilot Cup 2 < GY SC3R < Sport Cup2R
GY SC3R are pretty much the fastest 19" tires I can run other than Pirelli PZero slicks in GT3RS sizes of 265/35/19 325/30/19.
Pilot Sport Cup2R are fastest but my god, that thing only lasts for ONE SESSION at that high speed. Then it just falls off a cliff. It's not a tire for practice use, that's for damn sure! |
That's great information. Johnathan's test agrees with your fastest tire experience where on a GT3 RS he found the Pilot Sport Cup 2R was the fastest but he found the GY SC3R grip dropped off more between those two tires in his own circuit testing. See his lap time delta in the photo below from lap 1 and lap 4.
As mentioned earlier he conducted his test at Michelin's test center using a car on loan from Porsche.. and the Michelin won. The host tire manufacturer's product winning the test seems to happen a lot whenever Johnathan tests at a tire manufacturer's facilities.
From Johnathan's test: "The Goodyear Eagle F1 SuperSport RS, Michelin Pilot Sport Cup 2 R and Pirelli P Zero Trofeo R are regarded as three of the fastest road-legal track day tyres in the world. To find out which of these three semi slick tires reign supreme, I've borrowed a 991.2 Porsche 911 GT3 RS, and have use of Michelin's tyre test facility in central France to run my own tyre testing program."
