We have wilwoods on the cuda. Brakes are fine, but customer service was terrible. Make sure it all fits before you bolt it up, because once you bolt it up they won't accept returns/exchanges. I had a fit issue with my rear kit and just ended up machining the spacers to get the brackets to fit, because they wouldn't exchange the $25 spacers. I noticed the spacers had voids in them from a poor casting when I cut them down. I won't buy anymore products from them, but for now their brakes are on the car. They work fine, I just can't recommend Wilwood to anyone.
Cross drilled and slotted are a taste issue for street driving, some people like the look. On another note, I had to machine the dust cap so the center cap of the wheels would fit. Not sure if anyone else has had this issue though. American Racing AR500 wheels.
