I'm looking to upgrade my front brakes. I've heard that the rotors and calipers from a 1.8 will fit. How much bigger are these rotors?. Has anyone done this?

 

do a search...dave potter aka biknman did this swap..just a simple matter of swapping calipers and rotors from the 1.8....it is an effective swap, the rotors are 1" bigger..not quite a big brake kit, however definitely more stopping power
