Pass happens around 8:49 mark. Cant tell how hard both guys are pushing. There was a silver 12C in the slow lane early on, and a fancy sporty one towards the end as well. Looks like a great day at the track, kudos!
This session was an absolute blast! I was right behind the two of them in my Viper ACR. Spectacular driving by the Mac driver and both drivers were pushing fairly hard. However, there is more speed left on the table in the 458CH especially in the Carousel and curve up hill at end of front straight. This Mac was on Hoosier R6 tires and a special set of 19" wheels both front and rear. I would stay away from this particular set up. PM if you need info as to why.
Do you not think the difference is primarily tyres McDc..? Have no knowledge of the relative strengths of the two here, but certainly this time last year mat spa the challenge didn't walk away with 12c on p zero?
