Rotora Big Brake Kit

I have been having a reoccuring problem with my front left caliper sticking. Not so good for brakes or gas mileage these days. So I was looking to upgrade my brakes a bit seeing that I am going to be spending some money anyway. My car is completly stock. I saw a articale at this site. http://www.racetunedimports.com/MR2_brake_kit.php
About the Rotora brakes.
Is anybody familiar with these. I would like some input before drop a dime for this. I need at least 17"s to fit the big calipier but I am just getting started so I guess i have to do it all at once.
If anyone has rotora brakes and or know anything about them on Mr2's please let me know.
