Any ideas?
I have about 40,000 on the clock and reckon I warped the rotors at around the 35k mark. Started to get vibrations in the steering wheel when braking at speeds over 80 kph.
I tested the discs with a runout gauge before machining and sure enough they were warped.
After the machining the vibration went away but I also noticed that I have quite a few hot spots which are located about an inch from the outside and are inline with every internal rib that holds the 2 discs faces together. Either way after the machining the min thickness has been reached.
So I need some new front discs. I looked at the DBA 5000 and DBA 4000 series. The 5000 are a 2 piece about $500 each and the 4000 single piece are about $330 each.
Any suggestions on a disc? or who makes them for a Z
