Fitted the new rear discs and pads today to my GSi (93186301 vented disc with pads for both sides - £74.50) and just of idle curiosity I've had a gander at EPC for the specs.
Now the point of the post is nothing to do with how easy they were to fit (no need to remove caliper carrier unlike Mr Haynes version), but more at the size of the beasts.
Being a 3.2 GSi the fronts are 314mm x 28mm vented.... fair enough.
But the rears are 292mm x 20mm vented ! That's meatier than the fronts on the 1.6, 1.8, 1.9, 2.0, 2.2 and only marginally smaller than the older 302mm fronts !
Even more shocking (to me at least) they are only marginally smaller than the fronts on my old 3.0 Omega (296mm).
Now it's nice to know I can stop without undue effort and that I now have lovely fresh discs and pads on the rears, but I hadn't quite realise just how meaty they were.
