This topic may have been asked before but I could not find it, so here it is again...

I own a 2007 S60 2.5T AWD with 11.25"/286mm rotors. The car has 80K miles on it and needs a brake job. Front rotors OK. Rear, one scored, one OK.

So, why not consider the 305mm S60R upgrade, I ask myself. Both calipers, discs and SS brake lines, front and rear.

What I don't know is, will I need a different caliper mounting bracket?? I assume Yes. But is that all?? Is the spindle and hub etc. all OK on the 2.5T for this??

Will the 17 inch wheels work with this configuration?? or are the 18 needed (yes, desired, but needed??)

Any ABS and traction control issues??

Anything else??

Advise really appreciated....
