Fit the air guide -1- on the wishbone -3- .
The air guides are supplied as an installation set with new GT vehicles (from 2010 model onwards).

Requirements: The area in which the parts will be attached must be clean (no dust).

Preliminary work: When retrofitting the air guides -1- on model year 2007 and 2008 GT3 vehicles and when replacing the air guide -1- , attach (affix) the adhesive tape -2- beforehand.

Note the position of the adhesive tape (described under 1.1).

For new vehicles (GT3 from 2010 model onwards) , the adhesive tape -2- is already attached (affixed) to the air guide.
