Buying new track tires for my 2015 C2S. Looking at RE71R and Cup 2s. I run in the intermediate groups at my DEs. Cup2s are $350 more expensive than RE71Rs. Are they worth the difference in $ or should I pocket the $ and put it towards my next set of brake pads? Thanks guys , really appreciate the input.

I switched from the SC 2's to the RE71R's about 5 sets of tires ago. Never looked back.
The Michelins may last a bit longer, but for me, the grip with the RE71R's is a lot more than the Cup 2's.
I love mine and will never switch back.

Good luck....

Don't drive a Porsche and have never used the Michelins but absolutely love the RE71Rs--sticky in dry and awesome in wet. Had them on last week at the Glen and they were fantastic during nearly 3 hours of track time in torrential rain.

Forget RE71's and Cup 2's - Michelin Blues FTW!

Go with the RE71R and pocket the difference. Do not run past 34psi hot, as they get greasy. Most prefer to run at 32psi for optimal results.

The CUP2 is an excellent tire, but it has a very small peak operating window. After that, they don't give the same feedback and drop off a little, but stay consistent for quite a while.

I hope this helps.

If there is the potential for HPDE's in the rain, definitely get the Bridgestones. If you are the type of driver who only goes out on a dry track, I think I'd pick the Michelin. I have a set of RE71R's. They replaced the OE Pirelli PZero. My logger malfunctioned my last time at the track so I don't have actual lap times to compare, but the butt dyno suggested RE71R's are no faster than the PZero. I'll be back at the track in a couple weeks. Hopefully the logger works and I can compare objectively.

Agree on the psi for these tires. When they hit 35 psi on the track, they get greasy for sure.
I like to start at 26 and after a couple laps, I'm usually right in that 34 psi sweet spot.
Good call on the pressures.

34F/32R COLD for my fwd car with no camber--the better to get 'em slidin'

....just grateful they're available--they were unobtanium from May 'til August in my size; had to use the new Direzzas instead. 1.5sec/lap slower

Cold at 34/32? Wow!!

You're a much better driver than me, that's for sure....

With 121hp if you're not getting slip angle, you're (I'm) slow. Really true for most cars as discussed in previous threads.....and we'll be slidin' round Mid-O Friday for sure!

Like I said, you're a much better driver than me.......

For the track RE71r is a couple seconds faster (at COTA in a GT4) and wears better. It's really easy to destroy a set of cup 2s if overdriving the car's grip. Cup2s are better on the street. Cup2 is closer to a Super Sport, and RE71 is closer to an NT01 from a civility standpoint.
