I drove it before the expansion. Small group, interesting cross section of cars. Lots of fun. I am told the track has improved since then. Last time I was there I watched a ‘67 mark IV doing laps.
Am I wrong with this, but I think this will mean your odometer is going to show about 5% more miles than you have actually driven based on the rear tires being 11 mm (about 0.4 inches) smaller than the original tires.
