Hello american friend,

I have the opportunity to install V60 Polestar front brakes on my Volvo D5 AWD (sorry it's a diesel but 240ch anyway, lol)

Who has already installed Polestar front brakes on a standard V60 or S60? What should I change others? Brake cylinder? Power cylinder?

Thank you in advance for your recommendations and advice

Kevin from France



For information, I already have the rims Polestar 20 "

I did it, I bolted on the dust shield, calipers, polestar brake lines and rotors. I believe the polestar brake lines are longer than the standard one or at least I was told so I installed them too. You don’t need the brake booster or power booster but I have one for when I do my back brakes to larger ones.

The first question I would have is "Is the piston area the same?" If the Polestar front piston area is greater and you do not install Polestar rear brakes (if there is such a thing), the brake bias will move forward. This may or may not be a problem, but it certainly not something Volvo tested.

The rear polestar brakes are the same as a stock V60/S60 rear brakes so it doesn’t affect braking bias at all. Brakes the same as a stock polestar

Everything is the same except the pad.
31408670 is the current part number; its predecessor 31408061 (the pad my car came with stock) has a DOT pad code GG which is the highest friction rating for iron brakes.

It's not. You're guaranteed to shift brake bias front which is fine as understeer is a safer character than oversteer.

Here's a bias calculator and my own research on the matter.

For your information, the Polestar rear rotors and calipers are identical to ones on the P3 XC60's but the brake pads are HP2000 GG. Stock V60/S60 come with solid rotors, not vented ones.

For your information my 2016 V60 has vented rear rotors from the factory which is why I said the rear brakes on the non polestar cars are the same as polestar cars with the exception of the pads (didn’t know that before about the pads)...

Incorrect in the US/Canada. My 2012 came with rear vented rotors from the factory.
I see. My MY16 V60 T5R comes with rear solid rotors. MY18 Polestar comes with rear vented ones. Size is the same, 302mm If I remember correctly.

We can easily change by solid or ventilated rotor, in France we have the choice between 2 in store

So it's quite simple installation, the replacement is simple enough finally, I was afraid of having to change the brake booster or power booster.
So I will buy.

Sorry to rain on the parade here, but why add the polestar calipers to a AWD D5? Seems to be a bit of overkill for 190-240hp D5?

Wouldn't it be easier and cheaper in the long run when you have to start replacing pads and rotors to upgrade to the 316mm rotor/caliper combo from the T5, or step up to the R-design or XC90 rotor/calipers?

Because I have the opportunity to have these brakes (see the photo) for cheap and as I install all the elements of a V60 Polestar on mine, this is the opportunity and more the braking is bad on the D5 so I'll solve this with these brakes

It's the color : Cosmic White (It's a pearly white with gray highlights), it is not available in the United States?
Cosmic white was not an option for V/S60s in the states. Last time we saw that was on the C30s!

It's a shame, she's beautiful this color.

It's an option in France but there are not many.
