In my Nissan GT-R on March 15 2009. I moved up to the Yellow group a month earlier but imo only because the car is so darn good. I ran this lap in 1:56.6 on a slightly damp track and as you can see there is a lot of room for improvement, but a sub 2:00 here is impressive regardless. 

I've shed over 20 seconds off my best lap since I first started driving on a track 6 months ago. I good driver could probably break 1:50 in this car. 

Only mods are an HKS USA resonated midpipe and some Ferodo DS2500 brake pads that replaced the worn OEM ones..
