Hey mike I live in Sammamish also and have a z51. Are you familiar with autocross? Checkout our upcoming Autocross school at
http://www.nwacconline.com/2017PDFs/...choolFlyer.pdf.
It is a great place to learn your car capabilities. I saw your post about PTM Wet and we can help you get familiar with that new z07.
