Suspension Setup wrong?
So I have measured my preload and set it as best I can with 2 people. I know the rear is accurate, front may be off as much as 10mm, in either direction. However, when downshifting under braking (in first especially) I hear a little bit of a tire chirp. I am almost 100% certain it is not from the front, as the front does not appear to slide or lose traction under braking, and while I have had the rear squirm around when I am braking hard, it was only after setting up my preload that I noticed a brief chirp.
Anyone have any ideas what would be causing this?
