Remember we are running street tires and John Mathews stated that we SHOULDN'T be going through turns 7 & 8 (first set of chicanes) at 100 mph. Not that we couldn't, but shouldn't at our level on street tires... not enough stop to have a big safety margin.
I have video of me hitting them at 95 mph for sure. I don't know if I got my 100 mph pass on video or not.
Oh... and by the by... John Mathews is the HPDE Director and an excellent course driver, so I'd take his advice any day. I had him drive my SRT6 at Buttonwillow Raceway last November and he knows his stuff... BIG TIME!
Just because we 'can' doesn't mean we 'should'. Now, maybe when we get to level three or have better tires and brakes (I'm half way there) then, he might say you should...
