I just received a 2-page fax from my Porsche dealer, dated 5-3-05:

Vehicle Type: Carrera GT (980)

Model Year: As of 2004

Concern: Raising vehicle ride height

Information: To reduce the risk of the vehicle underside bottoming out and/or getting high centered on uneven roads, speed bumps, steep angle driveways or parking garage entrances, the chassis on the Carrera GT can be raised.

Front axle: 10 mm /rear axle 9 mm

This is done by installing longer push rods on front and rear and increasing the spring preload (on rear only). The spring preload is modified by turning the concave washer clockwise by three turns. Raising the chassis does not affect driving behavior in normal driving conditions.

980.343.257.04 (1) Front axle push rod, left
