Overall rating: 4.9 / 5 from 594 reviews.
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
