To keep it short and sweet, I am curious as to the stock thickness of a new brake rotor for a 4 lug FC. My engine mods are just about complete and in my SIG, now it is time for suspension & braking component upgrades. I have found a decent set of 4 piston Wilwoods for ~$100 a piece brand new.

 

At your level you may want to go to the 5 lug setup, this will allow you to go to a vented rear rotor.
