Looks good. Spill the details :p
Doesn't look like you went for the 336mm with xc90 carriers?

[S60-MBS]

After suffering from major rear brake failure lastweek, I decided to do all the work myself.Being so §§§§ed off with car had totally forgot to call GRN motors to cancel the appointment for the front brakes.
I had the big calipers off Tim Williams £110 for calipers, carriers and sliders, all in very good condition.
Other Parts needed:
320mm Brake discs,
New police spec pads,
Longer Volvo hoses,
New bleed nipples,
Fresh brake fluid (atleast 1ltr, I didnt buy enough)
New longer caliper carrier bolts - very important.

After removing old calipers and carriers and hoses, the entire hub area was cleaned down. When trying to fit new bolts I discovered the holes in hub and deflection limiter are too small for new bolts and larger carriers. A titanium step drill and blacksmiths drill was used to make the holes larger (15.5mm).
The deflection limiters were a bit a headache, the material is a lot tougher, I had to use a machine shop and its lathe to make the holes larger (16mm).





Once the holes were sorted out , the refitting process began. All parts fitted perfectly, then I realised the half a litre of brake fluid is not going to be enough as it took about 250ml to fill up one caliper
Bled all 4 calipers just to be on safe side, clean up and road tested car and it really stops now.
