Chase Bays Clutch Line w/ Tilton Flow Control Valve Subaru WRX / STI 2002-2007 / BRZ 2013-2020 / FR-S 2013-2016 | CB-WRX-CLUTCH-TFCV

The factory clutch line setup on the Subaru WRX, BRZ, Scion FR-S, and Toyota 86 / GR86 is inefficient and outdated. With three separate segments and four unnecessary connection points, it creates spongy pedal feel and adds clutter to the engine bay. The Chase Bays One-Piece Clutch Line solves all of that in a clean, performance-ready package.

This is a full-length replacement from clutch master cylinder to slave cylinder—not just a soft line replacement. Designed for improved pedal feel, reduced heat soak, and a significantly cleaner look under the hood, this upgrade delivers both form and function.

Features:

• True One-Piece Design: Replaces the entire OEM clutch line system, from master to slave, eliminating unnecessary connections and failure points.

• Improved Pedal Feel: Tighter, more consistent clutch engagement for performance driving and racing.

• Premium Construction:

  • -3AN Stainless Steel Braided Hose

  • DuPont Type 62 PTFE Inner Liner

  • Black PVC Coating for abrasion and heat resistance

  • All Stainless Steel Hose Ends

• 9000psi Burst Pressure: Built for extreme environments and heavy-duty use.

• Direct Fit for OEM or Tilton CMC:

  • Includes M10 Banjo Bolt for OEM Clutch Master Cylinder

  • Use 3/8-24 Banjo Bolt (included with Tilton CMC from Chase Bays) for Tilton setup

  • Just swap the bolt—line is compatible with both

Optional: Tilton Flow Control Valve (Delay Valve Upgrade)

Reduce drivetrain shock. Protect your diff, axles, and gearbox.
This optional upgrade adds a Tilton Flow Control Valve to the clutch line system, changing it from a one-piece to a two-piece layout with the valve mounted mid-line.

• Minimizes Shock Loads: Allows slight clutch slip during aggressive engagement (e.g., downshifts, clutch kicks)

• Protects Driveline Components: Reduces chances of breaking axles or damaging differentials under load

• Track-Tested Results: Proven to reduce breakage in high-powered drift applications

• Unchanged Pedal Feel: Does not restrict clutch disengagement or alter modulation feel

"We tested this in our 500hp E36 and 450hp JZX100 drift cars with zero failures over a full season. Our 410hp ZN6 broke axles without it—three events and zero issues with the valve installed."

Note: While this reduces drivetrain shock, motorsports inherently carry risk—no guarantees can be made regarding breakage.
