A lap around the ridge in a 675LT with top down!

I have always wondered will a stock Mclaren run sub 40 at the ridge, obviously I didn't do it, but with more seat time, a fresh set of tires, and better driving, I believe a completely stock 675LT could do 1:38s in a cooler day. 

2016 Mclaren 675LT spider, 
Stock, 0 mods,
235/35/19 3R 6th heat cycle,
305/30/20 3R 10+ heat cycle.

It actually makes me sad how fast this thing is compared to my R8...
