[s-cars] S4 brake rotor spec question

[James Murray (LMC)]

Some (don't know the extent) of the data that Jimmy has posted on UrS4 is
from the Haynes Manual and not Bentey so that might explain the discrepancy.
You'll also find a discrepancy with the respect to Bentley and what Haynes
lists for wheel alignment, go with the Bentley figures...

Cheers, /J.

	Does anyone know if the S4 brake rotor thickness specs in Bentley
are wrong or out of date?

	My Bentley shows:
	Front rotors
	New: 30mm (1.18 in.)
	Wear limit: 28mm (1.10 in.)

	Rear rotors
	New: 20mm (0.79 in.)
	Wear limit: 18mm (0.71 in)

	But, I just noticed the urs4 site says the following under Technical
-> Brakes
	Front - 276 x 25 mm, one-piece, vented
	Rear - 269 x 25 mm, one-piece, vented

	So, there appears to be a 5mm discrepancy on front and rear between
Bentley and the urs4 site.  Anyone know the real truth - book out of date or
if Audi made a design change somewhere along the way?  I haven't taken the
obvious next step of pulling a wheel and measuring one.
