I ran VIR full @ 2:14.32 yesterday
Weather: approx 90 deg. & High humidity
M4 Mods: 285 square RS3 (street tires), JRZ, Pagid RS29
Timer : Harry's laptimer app paired w/ 10htz external GPS
(I'll post a video when I figure out how to)
You could also post that Donnie Isley ran a 2:09.6 at VIR FULL with a bone stock M4 featured in grassroots racing, he is an Instructor for BMW Performance Center and ex-Pro Driver....That way we all that run VIR have something to aim for
