The tires were fantastic all weekend. Lots of grip, good audible feedback, and heat up quick even running first in the mornings (more than my R-S3's did). However, by the 5th shootout run, which were only about 3 minutes apart, they were greased. I ended up with a DNF coming out of a 180 sweeper into a slalom....front end pushed and hit the first pointer while holding the same line as previous runs.

Congrats on the win! I was just happy to be somewhat competitive considering my tire handicap.

The Wilmington Spring Pro is capped. The two Toledo's line up with family commitments, so I'm looking at the Wilmington Summer Pro and Match.

YES!!! I'm not the ONLY one with similar setup!!!!

Do you have any videos of your runs?

I am on 275/35-19 re71R and run EXACT same pressure 39F and 34R cold. I have rear 8/10 stiff and front about 5/6 stiff (and looks like I should bump it up half a turn maybe?). Everyone tells me to do otherwise (super soft rear and stiff front and honestly, I didn't like it at all.)

Question, do you have any trouble getting grip in super super smooth asphalt venues? I'm experiencing a little under-steer or lack of front end grip with this setup in just ONE of my three venues? other two venues I'm fine. This venue has a slippery super smooth newly sealed asphalt. In this venue, would you soften the front koni a bit or stiffen even more to 80-85%?

I have a bit of info on the wear of the tire, I'm on these for a daily tire as I frequent the dragon. They are wearing much faster than the RE11 for me but I typically run 33/30 cold pressures. May try bumping them up a bit and seeing how they react.

This is the first tire I've ever owned that sounded like Velcro peeling off the road everywhere I drive. That doesn't mean it's that sticky, it just makes a weird noise.

I think our setups are very similar. I have 275/35-19 RE-71R too and Koni's and Eibach front sway full stiff. I just got back from the Utah Match Tour in Farmington, UT. It was a new location I guess and it has new asphalt. I was only able to place 4th on the first day and missed out on the shootout. However I got randomly drawn into the bonus shootout and finished 2nd there. In regards to your comment I noticed these tires weren't fans of the afternoon heat which was hovering around 100 degrees, I'm not sure what the surface temp was. Traction dissipated and the surface was slick almost grease like. I think they're awesome tires and they're wearing quite nicely. I have 24 runs on mine and probably 200 miles of actual street use on them. They have this weird 45 degree wear thing going on though which I guess is normal because other local drivers are experiencing the same. Still good amount of meat left.
