I haven't driven at Sonoma/Infineon/Sears Point for 3 to 4 years. First time driving my 2013 BMW 135i DCT at Sonoma. What a fun and challenging track. There are quite a few fast cars and great drivers in the advance group.
Currently running Kumho V730 245/40/17 fronts and 255/40/17 rears with over 7 track days on them. I also use these wheels/tires on my BMW 128i. These tires last but traction started to degrade. I am too cheap to throw them away :) I managed to squeeze a 1:56.26 lap. I had only driven 3 track days with the 135i so far. With fresher tires and more seat time with the 135i, low 50s is achievable.
Always enjoy doing track days with LightSpeed. They offered 8 sessions and only 3 groups at this event, you can't beat it. Thanks LightSpeed.
I will be posting more videos with my 135i, 128i, Cayman S and Spec Boxster. Stay tuned. You are welcome to subscribe to this channel. Thanks for viewing!
