Where can I find braking distance numbers from 3rd gen Camaros ?

I would like to upgrade my J65 4wheel disc front to C4, so I wonder will I really notice a difference ?


Thanks

If you can lock up the wheels with your current brakes than you will not see any decrease with bigger brakes. Yes, they will look cool and give you better consistency with less fade, but they will not stop the car any quicker.
The biggest improvement in stopping will be from TIRES! Or weight reduction. Weight is the enemy!
