They were the Road Course compound. I did, unfortunately, run them as stickers - I ran out of time so I couldn't get them scuffed or heat cycled before Lime Rock in May.
I put them through 2x 20 min practice sessions, 4x 20 minute qualis, 3x 20 minute qualifying sprints and 3x 25 minute races on a ~2700 double A-Arm FWD car before both fronts were corded on the inside. The rears still look ok.
Maybe I should have them heat cycled beforehand next time.
