Hey

I’ve just got some new discs and I’m measuring 0.05mm difference in thickness on each disc, high to low. Straight from the box, not fitted yet as doesn’t seem right?

Not a good start 0.05mm when shooting for 0.15mm max run out when fitting,?

car is e65 745i

/u-nanimous

that’s what I am trying to figure are the discs not ok before i fit them, but yes I will be fitting a testing runout. And no they are aftermarket and I’m dubious of there quality,

yes got a few surface plates not calibrated but checked with a calibrated dti 😝
