a local shop told me if i get a spec stg 3 or 4 that i need a spec billet flywheel too or else i will get lots of chatter is this true? id rather go the cheaper route and just resurface my stock but not if it makes driving it horrible. any info?

 

The Spec 3 and 4 stage clutches will have a lot of chatter with whatever flywheel you're running.
