Purchased Ebay Wave Rotors from Brake Disc Factory
First of all I don't have my camera with me so I don't have any pics but when I get it back I will post them up but we all know what they look like. I wanted new rotors for a while now and to be honest there was nothing really wrong with my stock rotors but I try to save weight when and where I can. Also I have often read the wave rotors do improve side to side handling.
After reading all I could on the Ebay wave rotors I decided to go with Brake Disc Factory because their rotors were advertised as being 5.5 mm thick. My thinking was if these wore faster than Galfer, Braking rotors or even OEM they would at least last has long as OEM rotors because of the thickness. I know that depends on if the metal make up is the same as OEM. Anyway I ordered the black set and they were out of stock but the person told me the black ones would be ready in a week. I got a notice that they had shipped on the 18th of April and I recieved them on the 21st by Fedex. Not too bad considering they come from mainland China. The rotors were well packaged and they looked really good, not very much machine marks on them. The rotors weighed less than OEM by a noticable margin but I didn't weigh them. I used my cheap Frankford Arsenal calipers and measured all three rotors. The fronts measured 5.7 mm and the rear 5.1mm. Now these cheap calipers could be off but they have always come close enough for me when reloading.
Anyway I mounted them and started to bed the old pads. The old pads were almost new so I wasn't going to toss them if I could help it. The first thing I noticed was the initial bite. This seemed to be a little better with these rotors. The Carbone Lorraine pads are not known for strong initial bite but these rotors improved that. The side to side transition was definitly improved, I couldn't help but to smile. After doing about 10 55 MPH stops I got her up to 90 MPH, began to brake and didn't notice anything out of the ordinary. I did feel the ever so slight pulsating in the lever from about 15 MPH and down. As I got slower the pulsating progressed but when it became apparent I was already stopped. I wouldn't have noticed it at 15 MPH if I wasn't concentrating for it.
So far I am happy with the purchase and I will keep this thread updated every five hundred miles or so until I'm confident that these are at least as good as OEM. I mainly ride street but I have purchased two track days for August so I am curious how these wil do.
