Question About Calipers 
Have an 02 TA.My next mod is a caliper upgrade.
I W/ like to go with Willwood, I looked on the Summit Racing websight and Im not sure which kind to get.
Do any of you have caliper upgrades?
If so, what kind do you have?
ALSO, how many pistons do our cars have?
I only run the car at the track only 1-2 times a year on track days.
I have cross/drilled/slotted rotors on all 4 tires, but I want the car to be able to stop the second I hit the brake pedal.
Do you think a caliper upgrade W/ do that?

The way I look at it is the F-bodys and Vettes share the same Calipers. Vettes get taken to the track repeatedly and very few ever have issues. Unless you are REALLY going to track the car and do some hardcore racing with it, I wouldnt' think a caliper upgrade is necessary. They are extremely expensive and I don't think you would notice as big of a difference as you want.
As someone already mentioned the drilling is just a bling factor. Look at all the real hardcore race cars. No slotting, no drilling.
For me, I rarely if ever make it to a track, but I do lots of "spirited" driving on the backroads and twisties of Austin. I went with Hawk HPS pads all around. Went with stock sized blanks for the back and did the C5 rotor upgrade to the front along with the stainless lines. This all by itself made a HUGE difference. The C5 kits are readily available and parts are relatively inexpensive. This setup works great for me and the stopping power is great. I couldn't justify spending 1000+ on brakes. I have maybe 500 in the front and back and am VERY happy with it.

However, swapping the Corvette calipers onto an F-body will result in a decrease of front brake bias and limit the clamping load on the pads a bit more than the F-body calipers would. So, it's actually going the wrong direction (unless you add the C5 rotors with them). So, though it's a better caliper, it's not going to show the gains the thread starter is looking for.

So, they are a similar design, but not really the same caliper at all. The Corvette calipers also hold up much better under track conditions due to those changes.
