LT1 brake upgrades...
 

I'm looking to upgrade the single piston front calipers on my LT1. I know the first step is to get LS1 spindles and I can get the 2 piston calipers and rotors for only slightly more money.

So, where should I take it from there.
What is the benefit of the C5 upgrade or should I consider spending more and doing the 4 piston CTSV caliper with C6 rotors? I have 18" front wheels...
The car is just a weekend canyon carver, will the LS1 brakes be all that is needed?
