To be fair to Pirelli, they fulfilled their brief pretty well to the letter - the FIA asked for the tyres to wear out much more quickly than we'd seen with the Bridgestones. It's not that Pirelli can't make good, long lasting tyres, just that their brief was to make tyres which wear out rapidly.
I have to agree with that as well. I suppose I should just keep my fleeting brain crepitations to myself

That said, when I've run Pirellis on a road car, I've generally found them to be very grippy but shorter-lifed than other makes.
I went off and done me some research F4-wise this weekend and changes to the Accel and Launch stats for all the cars (that I checked) would seem to bear this out.
My search/research was mostly based around the Muscle Cars. Here's what I have so far without having actually seen the Shelby garage.
- Class structure appears to be the same, with the same limits.
- 16 of the Fm3 cars made the transition to Fm4. Gone is the '68 GTO. Included is the '60 Vette.
- So far, there are 11 cars included in the base set. This includes the '78 King Cobra and the '77 Trans Am. Both of these have strange Pi values. Also included is the '57 TBird.
- Then there are the 10 cars from the American Classics pack.
- Plymouth returns as a Manufacturer
- 3 new Chevies, 3 Dodges, 5 Fords, and 5 Pontiacs. Most others just got a single entry. The Corvette count remains the same.
- All of the carry over cars received a substantial increase in Pi, putting most up into the mid/low D Class. The biggest mover (so far) is the '60 Vette with 79 Pi points, the '69 Z-28 is next with 73. The smallest increase was the '70 Challenger with just 4. Many were 69, with most in that neighborhood.
- The Accel and Launch stats all show a substantial increase. Handling gernerally took a tenth or two hit. The drag racers are doing their happy dance, no doubt.
- All in all I make it 37 old American cars (so far), 30 of which can be considered legitimate Muscle Cars.
Now, on to what has developed into a steaming issue over on the Daught GNet. The AWD Pi change. I have only looked into one car, but it was enough for me to see the lay of the land in the New Deal. The car I checked is what used to be the best car in the game, the 1995 Mitsubishi Eclipse GTS.
The Pi hit was rather substantial. From E256 to C358, that is 108 points!
Changes to the stats:
OLD: 5.7 5.0 3.7 4.8 4.7
NEW: 5.5 4.7 5.4 6.0 4.5
The issue wasn't so much the default AWD cars, but more the ones with the AWD conversion and the Pi point break that they recieved. It is funny to note that RWD conversions received the same break, but somehow that never got mentioned in the crying sessions.
The Civic VTi has recieved a rather substantial increase to its Pi as well. Up 97 points from F163 to E260.
OLD: 4.3 4.8 3.0 3.8 4.6
NEW: 3.7 4.5 5.0 5.4 4.4
I think most of the changes are the result of resolving the ludicrous wheel spin off the line. This has been wrong forever and is one of the primary reasons I have run with the TCS engaged. The wheel spin was such an obvious kiddy ploy that I just couldn't stand to deal with it.
I think I will play with my spread sheets today. I just have to do something that is Forza IV related...
