1.) ET Streets, even the radials, should not *ever* be driven in the rain... not sure if you DD your Mustang, but its something to consider.

2.) If you want an economical tire setup, wrap your stock wheels with the tallest ET street you can get.

3.) If you want an economical and performance-minded wheel setup, get a set of Weld's in the smallest diameter you can and a set of the tallest ET streets you can.

4.) Turbo > SC in every area possible except for initial costs.

5.) Once you go FI and spend the initial costs for that low 500whp, what's to stop you for the extra few lbs of boost here and there for that 600whp - 700whp+?

6.) Don't buy wheels if you really are intending to buy big brakes later... you'll hate yourself when you realize your wheels don't fit anymore afterwards.

7.) Seeing a meaty tall set of tires is far more menacing than any sound any street car spits out.
