This was my first ‘Long’ track day in the C8. I don’t run this configuration very much – maybe 5 days in 3 years, so I’m slower than normal on it – lol.

Conditions: 92 degrees, moderate humidity, light winds.

Equipment of the day: Fresh set of Hoosier R7’s (275F/315R) on 18x10 and 18x12 Finspeeds. I tried to get a 3rd day out of my front G-Loc R12s, and that proved to be a big mistake. Very inconsistent braking after the first couple of laps of each session.. Very hot. I ended up packing it in after four sessions – I was really hot, the brakes were really hot and my laps weren’t getting any lower. :/

Outcome: Best lap was 1:48.71 in session 2 chasing a friend in his 488 Ferrari Challenge car.. I probably spent a couple too many laps chasing him in session 3 but doubt I would have bettered my best lap. I’ve previously run a 1:43.29 in my C7Z but the lack of downforce and relatively low horsepower of the C8 are more apparent on the long track than the competition course. I think the Porsche guys were running 44's in their 3RS’ which lines up with the C7’s times. I may run one more day this fall on the long track so we’ll see if I can get down into maybe the 46’s. Time will tell. 

Running mod list: ‘WolfpaqC8’ is a 2022 C8 Corvette Z51 and has magnetic shocks/PTM. Mods from ‘Factory Stock’: Lowered ¾” front and back on Paragon collars, GM-spec track alignment, GM brake ducts (now removed) Girodisc rotors front/rear, G-Loc R12 track pads front/rear and SRF flush.
