It's a lot, but I'm just happy that this product is available
(or will soon be available) for our cars.
I agree, it's necessary if you have big rims. Did you see that Monster Garage with the Escalade tail gater? Jesse James said something about how it's laughable if you see a car with 20's and stock brakes. I can't remember exactly, but you get the idea...big rims, big brakes. If you're going to spend 4k+ on rims then what's an extra 2.5k for the proper brakes
