JSR Civic FL5/DE5 Integra Type S Modified Slave Cylinder "CDV Delete" Honda Civic Type R

First, we start off with a new genuine Honda­ clutch slave cylinder and tear it down to remove the internal CDV.

What's a CDV you ask?

A "Clutch Delay Valve" is a plastic delay valve inserted in the cylinder galley of the clutch system and it's intent is to slow down the engagement or disengagement of the clutch fluid. The purpose is to slowly engage the clutch to the drive train without introducing shock to the internal clutch components, transmission, or cv axles.

When driving spirited we tend to power shift or shift faster than the CDV can handle, this causes gear lockouts or slight grinds in gears. With these modified slaves we have aided and improved these issues bringing back the old B-Series and K-Series clutch pedal feel.

We don't recommend deleting the Master and slave CDV, just the slave.
