wilwood coversions..what next??

The various Wilwood kits fill a niche but they really aren't "streetable" kits. Some people run them on the street just fine but that doesn't really prove much. Most of the Wilwood stuff is very lightweight and is designed primarily for drag racing and/or street rod stuff. They do have some larger kits these days that might be suitable for street use but you'll need to upgrade to 17 inch rims.

There isn't really any reason for people to get wound up about this stuff, there are a bunch of different vendors and the parts are all designed for different applications. The Wilwood stuff fits the lower end, lightweight cars, drag race type of applications. PBR has the mid-range and Brembo owns the top end. The OEMs tend to use cheap cast iron caliper and rotors whenever possible but on performance cars they'll step up to either PBR or Brembo. I don't think a single OEM has ever used Wilwood calipers or rotors for anything.

If someone wants to debate the subject then Rokketride is as good as anyone on the subject. He could provide a number of reasons why Wilwood calipers aren't of the same quality level as Brembo calipers. But I'm not sure why there is even a debate on the subject. Why would anyone think that a $600 disc brake kit would be as good as a $2000 brake kit? You tend to get what you pay for and the cheapest kits on the market are priced that way for a reason.
