I had 9 autocross runs on RE-71Rs yesterday. The tires also have about 4K street miles, including a trip from Miami to New Orleans and back. I can confirm that these are _the_ tires for my Miata and, later for my 993. "RE-71Rs are the best tires in the world. All the other tires are for the little girls" (c).
Seriously, I see very little negative in RE-71Rs for a sports car, especially the one not daily driven for hundreds of miles a day.

What are the particulars of each evolution?
Tirerack blog from 2015:
Tirerack blog from 2013:
A quick search shows just about universal preference by consumers for PSS over PS2. Google "michelin pilot sport ps2 vs supersport"

And Michelin...
PSS is cheaper as well.

The following are some of the key advantages of the Pilot Super Sport compared to the Pilot Sport PS2:
More dry grip
Improved fuel efficiency
Extended treadwear
Improved wet traction
Faster steering response
Reduced tire weight up to 10% compared to competitors

And Michelin...
Michelin’s in-house testing, performed at the Michelin Technology Center, helped identify six key areas in which the Michelin Pilot Super Sport outperforms its predecessor, the Michelin Pilot Sport PS2:
Road-holding on dry surfaces: Tests showed a 1.5-second gain on a 2,700-meter closed-circuit track.
Braking on dry surfaces: When decelerating from 100 km/h to a full stop, braking distance was shortened by 1.5 meters.
Road-holding on wet surfaces: Time was reduced by 2.5 seconds on a 4,100-meter closed-circuit track.
Braking on wet roads: When decelerating from 80 to 10 km/h, braking distance was shortened by 3 meters.
Total mileage on the track: 50% more laps.
Total mileage on the road: 10% greater distance.

+1 for the PSS or the 4s that sound like they're going to be even better.

These tests are not with N spec PS2's and apparently N specs are better. I just would not put a non N spec tire on my car.....

I just changed out wheels today for autocross and found that my PSS are pretty much shot after only 3000 miles and 6 autocross runs, not events, runs. I know performance tires don't last that long but that seems a little ridiculous. It looks like the wore evenly so I don't think it's the alignment and it's not like I do burnouts or anything. Should I contact Michelin about this? Just got a set of 17s for the much cheaper tires, went for Federal 595 RS-RR, cheaper for a whole set than just the rears with 18s. They stick much better than the PSS; they can rip your face off under braking.

Definitely go back at least to your tire dealer. I've seen lots of flat spotting and scuffing but no wear outs over the years autocrossing with PCA UCR. I use my 260Z and just switched out crappy Fuzion's after about 40 runs over 5 years.

I just don't understand why anyone would use an outdated design on the most important component of their vehicle. Particularly when it's one of (if not) the most expensive choice. And especially when that component has multiple companies competing with new designs nearly every year.
Just because our cars are ancient doesn't mean the tires have to be as well.
Thanks for your posts on the topic over the years, I've learned a lot.

Doing research currently on N-rated tires vs. Idlers. Tossup so far, but I'm still shoveling.
