I have an 89 Integra and it has the orginial clutch on it with like 124000 miles on it so naturally it's starting to slip so I gotta buy a new clutch.. Now my question is what is the difference between the clutches on ebay for like 80 to 150 bucks, compared to the clutches sold on car performance sites for like 280+? A buddy's brother-in-law gave me a quote for two, stage one at 280, and a stage two at 340.. but i can find a stage two on ebay for like 180.. SO whats the deal? Please someone help me, shed some light on my problem.
