Many of your clutch setups like the tex and the factory clutches come as a package with the flywhel thats already been balanced.

I bought all seperate pieces so had to get them ballanced. The dowels just ensure the clutch pressure plate always bolts back on in the same place. Also sometimes theres enough movement in the bolt holes that the pressure plate can shift position heach time its bolted down. The dowels keep everything aligned.

Cheers
