Just to provide some perspective: Sunoco GT 100 octane race fuel is $13.38/gallon at High Plains raceway in Colorado. My T3-spec 350Z finished second and third in two SCCA Majors races over the weekend, and is currently tuned for 100-octane fuel. I may have to think about going back to a...

I still have my '03 preorder Redline track and replaced the seats with newer power models. Been working on restoration details this summer and it's looking good after almost two decades.
