COBB Tuning Stage 1 Drivetrain Package Subaru WRX (GD) Wide Barrel 5MT

COBB Tuning Stage 1 Drivetrain Package - Subaru WRX 02-07 5MT (Wide Barrel)

COBB Tuning has spent over two decades developing Subaru-specific performance hardware that delivers genuine, measurable improvements. This Stage 1 Drivetrain Package is built around their Wide Barrel Shifter and targets one of the most common complaints from GD-chassis WRX owners — vague, imprecise gear changes. The result is a more mechanical, connected shift feel with noticeably reduced drivetrain slop.

This listing covers the COBB Tuning Stage 1 Drivetrain Package (Wide Barrel) for the 2002–2007 Subaru WRX (GD/GG) equipped with the 5-speed manual transmission only.

Note: This package is compatible with the 5-speed manual transmission only. It is not suitable for automatic or 6-speed variants.
