I have been a customer of Progressive Parts since 2018 and they have always provided parts on time and at a great price, especially during their various sale times during the year. In 2019 I booked my Audi S3 8v into their workshop to upgrade the ECU and TCU to the Revo stage 1 file with Mark’s sprinkle of genius into the tune it is still going strong to this day! Recently I ordered a pair of RS3 brake ducts as they were the best price and I knew they would be reliable with delivery. To that end I positively recommend their company and I believe you will not be disappointed.
