Depends which stage clutch you go with. the prices ARE listed on their site. I installed a stage 3 on my track car last year and negotiated a racers discount of 20% off list. Based on my prompting, Spec made some offers here on the forum but they fell on deaf ears... Now it appears many members are finally discovering my supplier.

PS: At the time, they were also willing to produce a lightweight flywheel, but nobody seemed interested in that either.
