This is my fourth set of Wilwoods. The two previous ones were on track cars which visited Sebring, Homestead, Moroso and Road Atlanta quite often. Sebring is quite hard on brakes. Never had any issues except wear and tear. Each set went a year and a half with no issues until I sold the car.

A friend also runs his E30M3 (with E46 running gear) in the red group and has been doing so for years. He is also on Wilwoods (granted it may be a different model)., No issues.

So in my personal experience, no issues at all. As somebody else said, for street use, it should be fine.
