Hey no problem!
I was running Continental Extreme Contact Sport tires prior to the Yokohamas. The Advans have been the first 200 treadwear tires I've run.
5 days on track - 3 open lapping days and 2 PCA days where we had 4 x 20 minute sessions + 2 x 30 minute sessions. I've got 1 more day planned on Friday July 3rd and I think they'll be pretty done by the end of the day.
I noticed my lap times improve by 10-15 seconds easily with the new tires. I also upgraded to Ohlins over the winter, so they may have contributed to the improved lap times as well. I'm not sure how many miles I got out of them, I need to download my most recent data and do some math.
I've got 2.5 degrees of camber on the front and 2 degrees of camber in the rear. The tires have worn pretty evenly all around, front and rear. We just swapped the tires side to side to get my last day out of them later this week since my 2 local tracks (PNW) both run counter clockwise.
I ordered tires in January and the Advans were all that were really available. I am thinking of going to the Hankook RS4S as well later in the season. My husband has those and got 15 days on track with them. He's a bit more aggressive than I am, though I'm catching up.
The RE71Rs aren't available in my track wheel size. I am considering putting those on my stock wheels as back ups though.
I hope that helps!
