Pirelli Trofeo R's vs R888's
Just wanted to post my first impressions of the new Pirelli Trofeo R's for DE events.
Background & Experience: I've been doing DE's since 2002 (since 2011 with the C5Z) with about 35 DE's under my belt - Run in the advanced groups typically. Over the years, I've run Nitto NT-05's, Toyo RA-1's, Toyo R888's, Kumho V700 Victoracers, Kumho V710's, Kumho XS's and Hooser R6's on various cars. These days, I only run about 5-6 DE's a year and I only utilize 1 set of tires for street and track so they must be dual purpose.
To start the year, I was on fresh 295/30 R18 R888's in the front and 315/30 R18 R888's on the rear. I corded one of the front R888's recently (too much street driving with aggressive negative camber) and decided to buy (x2) Pirelli Trofeo R's, after reading various magazine articles about how great these tires are on the new Z28.
Yesterday, I started with the Trofeo R's (22 psi cold - 30 psi hot) on the front and the 315 R888's on the rear (28 psi cold - 35 hot) and the rear end was all over the place!! Much more than with a R888 set up all around.
I switched and put the Trofeo R's in the rear and WOW, what a difference. The back end stayed planted and I was able to get onto the power MUCH earlier. The car just plain hooked up out of the corners. It was very surprising how much more grip the brand new 295 Trofeo R's (not shaved or heat cycled) had over 315 R888's with 5 track days on them (which I still consider to have DE life left).
To equate them to a well-known tire, I'd say new R888's have about 75% of the grip as Hoosier R6's. The Trofeo R's are about 85-90% the grip of Hoosier R6's. They are that much better than the R888's.
Coming home, I ran into a heavy rainstorm and the Trofeo R's did very well in the rain as well. In my opinion, they are one of the best dual-purpose tires out there. I'm planning to pick up another pair for the front and see how the wear is over time, but I can say that after 3 sessions yesterday, they are showing hardly any wear at all. Very impressive for a 60 treadwear tire. Definitely going to pick up another pair for the next DE event in October.

First rule is don't mix tire brands/models and compounds on the track as the compounds/construction are different from one to the other and you always want the best handling tire on the rear of the car. Even placing brand new R888s on the front may have compromised the handling since they probably would be better handling than well worn R888 rear tires.

Obviously, after the fact, it is easy to see your mistake was placing the freshest tire with the best grip in the front. However, there would be no easy way to determine which tire grips and handles better when you first installed the new tires.

Again, I was simply trying to state......what I feel is the superiority of the Pirelli Trofeo R's to the R888's. I had the wider tires in the rear as I thought the 20mm of increased width would even they playing field. It didn't, the Pirelli's offer superior grip, plain and simple.
I've looked everywhere without luck.

You were really quick out there Matt. Gettting on the gas early and really pulling hard out of the corners. After a few laps my 3 event old NT05s packed it in and I had nothing for ya.

As much as I love Tire Rack, you often can't use them to determine if a tire exists. You have to go to the manufacturer as Snorman did in the previous post. Yell at Tire Rack if you want them to carry size X of tire Y. If they get enough "yelling at", they may consider it.
As for the OP: at the price of those Trofeos, they'd better damned well outperform the R888s. What you can't answer (yet) is: will they be as robust as the R888s are? One great thing with Toyo Rs is that they last forrrrrrr ever. Specially if Tire Rack heat cycles them for you.

Woodman is showing them, they ain't cheap.

Just for comparison to the sizes I run (f/r):
R6: $373/$388
R888: $327/$296
Trofeo R $436/$520

Same as you. I have always run less pressure in rear.
Huge braking loads with a weight forward car & smaller tires on front, needs a bit more front hot pressure according to my tire wear and pyrometer.
Starting out cold the same normally results in a few psi higher on front for me.
