159 Ti Brake Pads/Rotor combo

[MattK]

For reference - my 2011 Ti TBi had 330mm fronts and 292mm rear rotors. I measured them 4 times through the wheel. Using the model/year on eBay and most of the auto stores said 330/274 and so the "matched sets" didn't work either.
From the Fiat ePer database the rotor specs were as follows (plus I used the Brembo site to get the OEM part number).
Front: part 51767384 330mm (thickness 28mm; centering diameter 70mm; height 40mm)
[Brembo 09.9365.21]

Rear: part 51767380 292mm ventilated (thickness 22mm; centering diameter 70mm; height 43mm)
[Brembo 09.9366.21]
I ended up matching the specs, another Brembo 330mm disc with all the same dimensions, and a third party disc because the Brembo 292mm ones were only available ex Europe. Got it all sorted for $540 delivered. Then the thrill of installation.

Decided not to fit them myself (yeah I know) but for anyone curious, those discs were the correct size and fitted without issue.
