Yes that's just the rain. However, you have to account the overall dew point as well which will effect the slipperiness of the track as well. GM is super conservative with their estimates. But, nonetheless a 7:31 estimated time for 2014 is super impressive. Porsche has the luxury of hand picking perfect conditions.BMW just ran the brand new M4 CS to 7:30 at the track.... goes to show the level of handling and overall performance the Z/28 has even to this day.
