Auburn's diff's are good on mild street/strip combo's. But they are not rebuildable so if you're awesome at the track launching on slicks or dr's I suggest you go with the Ford Racing or the Eaton diff. They are both rebuildable and clutch packs only cost $50. If you're really making it a purely race car, you might want to look into a spool. It all depends on what you want to do with the car. There is a different part for different applications. ~Brian
