I'm looking to purchase a clutch master cylinder and deciding on which bore I should choose. Wilwood has three options (.625", .700", .750"). Does anyone know the stock bore for the K20? Or is anyone else using an aftermarket clutch master cylinder?

Thank you. I called Wilwood and the rep. said they always recommend the .750". That made me wonder why they have different sizes. I figured the K20 used a smaller bore size because Honda clutch's always seem really light. I guess I'll go with the .625".
