I have been considering new Rotors all around on my 80. Someone here mentioned brakeperformance.com as having a lifetime warranty against warping. So the last few days I've been looking into them. Up until this weekend they have been advertising 25% off, bringing their 4 rotor brake kit about $365. Not bad! Then yesterday they changed their promotion to a 30% off Father's Day promo, All right! I said, but when I checked pricing, the same set was $395???. Turns out they adjust their MSRP to show a greater discount and yet the actual price is higher. This makes me wonder about their service when it comes down to needing to take advantage of the warranty. I am unlikely to buy from a company who does business like this. Does anyone here have something good to say on their behalf to change my mind?
