Installation Notes

No hardware is required. This re-uses push pins for lower slots and the upper section is clipped in using tabs on the diffuser.

build journal: Special series

When more is just more.

The GT style diffuser is a derivative of the 1:1 replica; 3x extended fins design are adding in the exposed carbon section of the diffuser for more aggressive aesthetics.

In this Special Series about the 1:1 CSL diffuser project, I take you into the details of what makes this special along with the backstory to this crowdfunding, development, unboxing, fitment reviews.

I sign off with my recommandations on if you should get the paint match service.

Cheers,
