First let me give you a great big welcome to the CCF, you must be a first class guy as I know all C4 owners are. We can never have enough C4 pilots in our mist. So welcome aboard.
As for the brakes, if you are like me and just do a bit of cruising and not beating up on your ride, it makes no sense to upgrade to one of the top notch systems that are available. But you also want to make sure you can stop your pride and joy when you need to. So I would be looking at the Hawk pads and maybe a nice set of OME rotors. Take your time and have a good look around at what is available. Remember that places like Corvette Central often have free shipping, but you could probably get what you need at your local Napa store.
Once again, I can tell ya how happy I am to have another C4 guy here........ The others on this forum will know what I mean by this.... LOL !
