Customer Reviews
Overall rating: 4.9 / 5 from 600 reviews.
The shipping is super fast, the rotors and pads are packaged well, the customer service is helpful, everything looks good. Parts Pioneer is doing a great job.
Parts came on time and were correct. I have the brakes installed already and they are working good. Sway bar end links not installed yet, but appear good.
I love PartsPioneer. The rear-wheel Positive Plus pads and Genius rotors fit perfectly on my 2019 Subaru Forester. Excellent quality at a fair price. Highly recommended.
Thanks for catching an error in my order and righting it for me, complete with email to say so! This … is what customer service head and shoulders above, looks like !! Well done all !!
Service was great, appreciated the phone call to confirm the vehicle. Parts arrived quick. OEM fit. Will be ordering brakes as you can see by the picture. Very impressed.
I have bought this rotor on part pioneer for my Q3 and installed and used for over a week, they are amazing no squeaks no noises brakes have improved 110%. This rotors are the best so far I’ve always bought rotors and used in all three of my cars and so far these ones are the best that I have ever bought.
Thanks
