'05 H2: Got Brakes?

[greenhummer]

So, I know the H2 weighs about 6400 lbs (without being loaded up with driver, passengers, dog, etc.). That makes it about 2400 lbs heavier than the sports sedan I'm used to driving that brakes on a dime.

After a long trip this past weekend, I got to experience some "emergency braking" first-hand. On one occasion, I did not find the brakes to be terribly confidence-inspiring.

The '05 H2 has stock wheels/tires on it. Do you get better braking when moving up to 22" wheels and lower profile tires? I know that one of the big brembo kits should improve the braking - definitely increase the resistance of the brakes to fade after a lot of braking. I'm more interested in just getting the H2 to handle emergency breaking better. I don't push the SUV hard enough to check out the boundaries of brake fading.

thanks,
