New Era Performance has GTO Line Lock kits for 04-06 GTO's.
An SLP exclusive, this unit is designed to fit both automatic- and manual-transmission GTO applications. Here's how it works: Press the brake pedal and flip the brake-control solenoid switch. Remove your foot from the pedal, and the solenoid maintains line pressure to the front brakes until the switch is released. This makes it easy to heat the rear tires in the burnout box, while minimizing wear and tear on your car's rear brake components. You can also use the system to prevent a manual-trans car from rolling out of the staging beams at the starting line. This kit is custom-fitted to the GTO chassis and is fully compatible with the factory anti-lock braking and traction-control systems. It includes a waterproof electrical solenoid, CNC-bent steel lines with OE fittings, all necessary mounting hardware, and detailed installation instructions.
