my car has also felt like this from day one. I test drove an SS and the brembos felt NICE. Instant grab, the V6 brakes me feel unconfident about the braking power of the car even though its great.
This is one of the things that has bothered me about the V6 Camaro since day one
The exact words i used was mushy as well when i described it to friends.
Hope we can get a fix for the mushy feeling. Its obviously no defect since it seems like a v6 thing only.
Hopefully theirs a solution to it
