"I have to say I am very pleased with my Difflow 5 element diffuser. I gave it to Valet Magic to fit as they have a GT-R friendly double post lift in their workshop and are familiar with taking panels off GT-Rs. Apparently it was a straight forward job and the result is great I think.
I like the contrast between the satin painted black ali and the matte wrapped carbon fibre of the Knight Racer valance. So provided your aftermarket rear valance allows the retention of the stock under-diffuser panel, it can accomodate the Difflow diffuser. Beautifully made." - 09' GT-R

"The Difflow diffuser is a work of art. If you are in the market for an aftermarket diffuser, get a Difflow. The alignment of all the holes was better than factory." - 07' Exige
