The 3.9 final drive setup from Tomei is an economical way of improving acceleration in the 350Z and G35. Increases available power by 10% per gear, resulting in faster acceleration in every gear. These gears really begin to shine with the larger staggered tire setups prevelant in the Z/G world. Professional installation required. Only for use on 6 speed manual transmission models.
It is highly recommended that an experienced mechanic install this ring and pinion gear set as excessive noise or even catastrophic failure can result from improper installation.
