HPDE alignment
Have an '09 Z06. Running Hoosier R6's for my one or two track days per year. Have stock alignment so I know I'm leaving a lot on the table. Since car is a 90% streeter, is it worth messing with the alignment? If I wanted to do it, what specs? Have some Pfadt specs but wondered what's working out there.

You are shortening the life of the Hoosiers by running a street alignment. You need -2 to -2.5 degrees front camber to keep from wearing out the outside shoulders. However, if you run that alignment on the street you will increase the wear on your street tires as well.

Also start to take tire temperatures. The temps will be your guide as to what the alignment specs should be. Here are the tools you'll need.
Also only use one tire pressure gauge. Tire pressure gauges are pretty inaccurate. You can solve the problem by only using one gauge. If you start to use a different pressure gauge you're basically screwed.
