Hello, fellow Swedespeeders!
So after a long wait, I finally got to installing the Rotora BBK on my MY18 V90CC T6 Polestar with 67,000 miles on the Odometer, and here is all my experience leading up to this point.
Background: My Volvo had its front brakes (Rotors + Pads) replaced at around 5,500 miles on the Odometer because of the brake issues most of us have faced. The Steering wheel shimmy and the Brake pedal juddering started to come back at around 60,000 miles on the Odometer. This is when I decided to opt for a Big Brake Kit instead of going in for an OEM replacement. Initially frightened by the expensive costs of the Brembo and StopTech BBK, I decided to carry on with my OEM brakes, but after seeing @visualv upgrade his V60 with the Rotora BBK and having good initial results, decided to go for it. I contacted Loren @Rotora and he is one of the nicest individuals I have talked to. Throughout my BBK buying journey, he has always been proactive and helpful.

My BBK was initially shipped with 355X29 rear rotors, and during the install, the tech found a fitment issue which would have needed us to grind the rear axle knuckle (which we did not). This caused a couple of months of delay, and shipping the rear BBK back to Rotora and they coming up with the solution and shipping it over to me. The newer Rear BBK arrived with 380X29 rear rotors (as previously mentioned) along with different caliper brackets and longer Brake lines.
The final install went smooth. The Install instructions provided with the BBK are awesome and a OCD like me really appreciates the clarity. It took around 5 hours for the techs at Waterford European to install both kits (front and back), and it cost me $520.00.
Being around 3PM in the greater Detroit area on a weekday, the entire ride home was slow-moving traffic. I did not want to test out the kit before I had properly burnished the brakes. So I maintained a somewhat calm driving composure and used the brakes minimally. The brake pedal has a slightly better feeling as compared to the OEM brakes, and even with the slightest engagement, the brakes grabbed much faster than the OEM brakes did. The pedal has a very short initial dead travel similar to the OEM brakes and I did not think much of it. Overall it was a positive first day experience with the BBK.
Finally, yesterday, I went out late night to try and burnish the brakes. I made around 10-12 high speed emergency (almost stops) from about 70-75 mph to 10 mph. I could not slow down further because it felt weird coming to a (almost) halt in the middle of the interstate. I can tell, I cooked the brakes thoroughly because after the 45 minute drive back home (with the temperatures being in low 40s), I could still smell the burning smell after I parked the Vehicle. The next morning, went to inspect the brakes and there was a nice gray-ish layer of pad material on all Rotors with my wheels covered in gray soot (brake dust).
I drove around a little today and the brakes feel noticeably better. They have more initial bite than before and an overall more aggressive bite through the brake pedal range. I might burnish them once again after observing their performance for a week.
Overall, very happy with the Rotora BBK and I hope they serve me for a long long time to come.
Please find attached pics which have been a long time coming!
Cheers, everyone, and a special shout out to @visualv, @Rotora, @Vivaperformance, @Power6, @kartboy1234, and @WunderWagen (who originally sparked the BBK idea into me years ago)!
Please feel free to ask me any questions or doubts and I'll try my best to clarify.
