The VX already has some pretty big brakes on it, just nothing you would phone home to mom about in the "visual" dept. Upgrading to Brembos was just the over-achiever in me wishing for more, heh.
Brembo fitment is a tricky problem. Mounting them on any car is pretty trivial, but getting the right wheel and/or spacer is the trivial part that not all cars have info on regarding fitment. Unless someone else has tackled the task on your vehicle make already, there is little to go by.
