Didn't want to go Cup2s again, so I purchased RE71Rs for the front thinking I would go to the 355 V720 ACR rears as a couple here have done successfully. Unfortunately, those tires are pretty much on backorder indefinitely.

Well got the front tires on just so I could drive the car, and the rear Cup2s still have tread but are deff heat cycled pretty bad.

Bringing it out on spirited back roads the car actually felt great, but could get the rear end loose, which means on the track tomorrow I'm expecting the car to be really loose at the rear.

So now that I have the Re71s up front, which I like BTW quite a bit. I need a good match to the rears.

Basically I'm thinking the 100 TW R compounds (Nt-01/R888R, etc) will take longer to warm then the Re71r. So maybe not the best fit for the softer compound fronts.

So for rears, maybe go Cup 2 again in 345/30/19, or stock rears? Again lookin to see if anyone has a better idea for getting me through this less then ideal scenario.
Id check if you can find G3s in your size for the rear.
It is very similar to RE71R in grip imo - albeit it will take longer to warm up, so as suggested above perhaps start in PTM Dry. Cheers!
