From Nagtroc. With stock wheels and tires.
All trackdays were done at my local 2.3 mile track called Mid America Motorplex and my previous best on the street tires was 1:42.8 - We had over 50 cars at the track that day including Z06s, a modded GT3 Porsche and lots of other cool cars and I'm happy to say the GT-R ran the fastest time all day.Switching to Pilot Sport Cups in an 18 inch
After switching to the 18" TE37s and R-comp tires (my only mod) I returned for one final session last weekend before they closed for the winter. Track temps were really cold and air temps were 34 degrees all day but I managed to better my time down to 1:39.7 which I'm very happy with considering what the Z06s run out here, heh. That's a full 3 seconds quicker on the r-comps, no other changes to the car besides maxing the front camber on the stock arms and re-setting toe to zero.
Who said the stock GT-R tires were real R compounds ?
