S80V8 front brakes suit v60t6?

Ex850R

It seems to be the upgrade for the s/V60 T6 that occurred in latter years, could be xc90 ones as well.
So I want to go with the 335?mm v8 ones on the front replacing the 316mm? Calipers, disc and bracket. Using 18 inch wheels already so fitment ok according to what I've been reading.
I can get all the parts, new discs and pads of course, second hand.
@Philia_Bear, any experience

I've not done swap stuff with P3 T6 before but interesting to work it out....
First question.... do the calipers on your P3 use M12 or M14 bolts?

Ahh, man, I haven't looked, I will have a quick gander before we hit the road in the S80, away for the weekend.
Mark has parts.
Looking at these too.

Plus viva stainless front lines.
And a 3.5 inch downpipe!
Might have to make that as the 1300usd one on viva reduces down a lot... Dumb.

Lots a room. Dunno bolt size, can look at schematics.
Xc90 calipers and discs same too?

Let me know if you need lines for it - I can have a set made up for you, and they'll be ADR approved.

Yep, for sure Ash, it's important to have ADR on those, please send me a quote plus recommended fluid for a flush and fill.
I value your opinion on the pads I linked to above? And what you would recommend in pads too.

On another post I have been told of xc60 calipers, use them instead on the bigger discs so pads to suit them instead as they have bigger surface area.

VolvoMike;c-138707 wroteThe different size discs won't make much difference as they run the same pad. You'd be better off swapping over to the XC60 discs and calipers as they are a twin piston sliding caliper and much larger pad area.

@AshDVS?

If you're using the same caliper and pad, this is true to an extent - you dont have an increase in clamping force, but moving to a larger rotor gives you an increase in performance via an increase in leverage.

Think of the 280 to 302mm conversion that is popular for the P80 platform.
Its a noticeable improvement, it's cost effective but it isnt night and day type stuff.

The larger caliper provides more clamping force (assuming larger dia pistons, or more pistons) and the larger pad gives more contact area with the rotor.

I am now loking at the 336mm discs , XC60 calipers and pads and carriers and S/S lines , ( pads and lines from you,discs too?)

no problem. Just yell when you're ready.

What was the outcome? I'm pretty sure the 09-15 xc60 brakes were bigger than the s60 T6.

See @VolvoMike s post above

Thanks, trying to clarify, do xc60 brakes need the xc60 riser to replace the t6 riser for height, or did volvo make the xc60 brakes taller by design (allowing me to just straight swap with new rotors)

VolvoMike

It's a straight swap. Buy the XC60 discs, calipers, backing plates and hoses and it will bolt on.

Steele

Last question (hopefully). Are all 2010-2014 xc60 callipers for the bigger rotors, or do I need a specific model?

VolvoMike

Should all have the same
