Went for the eBay version from factory2all. Delivery took about 10 days.
Fitment was tight on both sides. At first I was worried it was too small but after flexing the diffuser and playing with the bumper it fit right in. The holes lined up, 1 bolt is not used.
The carbon fiber looks good. The mesh grill part needed some adjusting, it was too close to the clips and kept getting pushed out. If I was to do any modifications to the diffuser, I would probably get a different grill, maybe smaller mesh.
