why not matched rotors ?

Get a lifesize picture of a 16" rotor and caliper and install it on the axle behind the wheel.

Actually though I just used a .22 hard point - the force of impact opens the holes up a little anyways.
If only I had a dollar for every minute complaint - I could buy those Baer rotors...

So, the rear wheels are not only bigger, but the rotors are smaller. This does give a lousy visual to the car.
The Z51 is, I believe, 13.4" in the front, and I don't know what they are in the rear, but they're larger than the base/F55.
I put the Baer EradiSpeed rotors on my F55 and it looks a lot better, especially in the rear. The front is the same size as stock (but drilled & slotted), but the rear is a 14" rotor. You get a bracket extender with the rotors to move the caliper out where it needs to be.
Click on "My Corvette Photos" to the left under my avatar to go to my gallery to see some pics (before and after) of my rotors.

I think the reason that the rears are smaller is that it saves money.

Increasing the diameter of the rotor will make no difference in braking power other than slowing down heat build up. Unless you increase the clamping power or increase the surface area, i.e. larger calipers, braking will be the same.

This is a benefit with or without larger calipers.
I have the 14" Baer EradiSpeeds on the back of my F55, and I have noticed no problems. I think the 'Vette braking is pretty much biased to the front anyway, and even though the torque arm is increased slightly on the rear with the bigger rotors, I doesn't seem to be enough to affect the ABS or TCS.
Anyway, it sure does look a lot better!!!!

Looks great! Probably fine for normal street driving. It's the wet and track driving I would be concerned about. Have you driven agressively in the rain yet? or on a track?
