then why dont u just get metal ones then insted of replacing the plastics ones all the time? any specific reason?yield said:I think what we are trying to say is that it probably won't matter too much. Unless you do a lot of track days or something. I had a plastic one get seized onto my hub after a track day (don't know if it melted or what?) but I consider them a wear item (i.e., I expect them to break,etc. fairly often) so I'm prepared to replace them yearly. If you're worried about it just get the metal ones and call it a day.
