Hi MagaDs,It's a bit complicated to do it, i think.
I'm trying to do an upgrade on my stock braking system, but for a 320mm volvo calipers, not the polestar you mentioned. this was expensive for me and not possible because of the rims.
From my searching in this issue you need at minimum 19'' rims to fit those calipers, new caliper braquets, find if they fit the original holes of the suspension arm, new brakelines and i think you need to reset the ECU information of the sensors, because it adds a lot more power and the stock pump could not get the job done.
But it will be perfect to fit!!!
All Right! nice explanation, good to ear, thanks.Hi MagaDs,
thank you for responding to my post. I did some research and spoke to a few technicians about the conversion. The technicians indicated that the brake upgrade is in theory possible, but at the same time, there is a large chance that I will encounter numerous problems and end up making the car's braking system unreliable.
they indicated that I would need to replace the WHOLE braking system. (virtually all the mechanical components of the braking system). I would need to get an aftermarket/ custom set of 19" rims with a sufficient offset to fit the calipers & discs.
The most plausible option would be to install an aftermarket braking system that could operate the calipers. The main problem would be getting the aftermarket system to communicate with the cars ECU. This is where the unreliably would creep in... The last thing I want to do is compromise the car's braking system 😅 So I decided not to pursue the idea any further.
