Real quick question for everyone. I have cayenne brakes on my car and I know that I the TT and Passat spindles won't work cause the outboard caliper mount face sticks too far out. Would it be possible to get it to work if I put a wheel spacer between the rotor and wheel hub on the spindle?
I went back to get better measurements on the steering arm length, comparing A3 (MK5) to TT (MK2). I get a difference of only 2.4mm rounded up. This is an order of magnitude different from the measurement that everyone has been using! So pretty much no difference between the steering on these two spindles unless this way of measuring is completely wrong...
The geometry of the entire spindle is different, so there are no good reference points to measure from without creating an error due to different diagonals. I created a reference plane by fitting a piece of plywood into the strut clamp, which happens to line up with the ball joint center on each spindle. Then I laid the ruler flat against the steering arm and held it square to the plywood. The ruler is in an archaic measuring system, but the difference is ~3/32" or 2.38mm.
