Just fitted the Works Paddle Shifter Kit to my 2005 Stagea Axis. Very happy with the results and loving controlling the manual mode of the auto through the paddles.
However, I must note that the 2005 model Stagea has a differently shaped column surround that does not correspond with any of the templates provided in the kit. While this is not a major concern, what made installation more difficult over earlier model Stageas was the distance between the brackets that hold each paddle is barely wide enough to clear the outside of the column surround. Mounting the brackets as low as possible and equal distance from the left and right edges is key!
Cheers,
Brett
