I kept checking several shops for the same part, so I built this: https://motorcompare.app?utm_source=reddit It matches stores by the maker's part number, not by title, so you only see the same part. I attached a chart of today's gaps. The 2004 WRX Gates timing belt kit with water pump is $428.75 at the cheapest store and $869.80 at the dearest. A Brembo front rotor for the BRZ / FR-S / 86 is $62 to $93. It is free, no sign up. It makes money from affiliate links, but they never change the order, prices are always sorted lowest first. Still early. I would love to hear what parts or stores are missing, and whether the matching ever gets something wrong.   submitted by   /u/Specificx [link]   [comments]
