Originally developed for the Genesis Coupe LSX engine swap, where the factory clutch master is undersized for an LS-spec clutch, but also usable on factory-engine Genesis Coupes upgrading to a Wilwood master.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe factory Genesis Coupe clutch master cylinder is sized for the OEM clutch pressure plate. When you swap to an LS engine and matching transmission, the LS-spec pressure plate is significantly larger and heavier, and the factory Genesis master can't move enough fluid to fully release the clutch. The pedal goes to the floor, the disc never fully disengages, and shifting becomes a mess. Upgrading to a Wilwood master fixes the volume problem, but you need an adapter to mount the Wilwood master in the Genesis firewall.\u003c\/p\u003e\n\n\u003cp\u003eThis adapter plate and rod end set is the solution: bolts the Wilwood master (Wilwood part number 260-10372) to the Genesis Coupe firewall and provides the correct rod end geometry to interface with the Genesis clutch pedal.\u003c\/p\u003e\n\n\u003ch3\u003eWhen This Is Required\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRequired for any Genesis Coupe LSX swap.\u003c\/strong\u003e Running the factory clutch master with an LS pressure plate WILL cause clutch engagement problems. Plan to install a Wilwood master with this adapter as part of any LS swap build.\u003c\/p\u003e\n\n\u003ch3\u003eAlso Usable for Factory-Engine Upgrades\u003c\/h3\u003e\n\u003cp\u003eYou can use this adapter to upgrade to a Wilwood master cylinder on a factory-engine Genesis Coupe if you want a stiffer pedal feel and more linear engagement than the factory unit. Not necessary for stock setups, but a legitimate upgrade path.\u003c\/p\u003e\n\n\u003ch3\u003eRequired Companion Parts\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWilwood Clutch Master Cylinder, part number 260-10372 (sold separately)\u003c\/li\u003e\n\u003cli\u003eFor complete LSX swap clutch plumbing, pair with the ISR 240SX auto-to-manual clutch line (IS-240-411) which serves as the master-to-slave line on Genesis LSX builds\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNote on the Full LSX Swap Kit\u003c\/h3\u003e\n\u003cp\u003eThis adapter is already included in the ISR Genesis Coupe LSX swap kit.
