My body shop said it doesn't work.

Ordered the parts listed in the thread for the 2017 rear diffuser from my local Lexus dealership for my 2014 F sport 3IS. My body shop guy told me the mounting points were incompatible when he tried to install it on my bumper. So, your mileage may vary.

My bumper is coming off to get repainted. Has anyone bought the aftermarket diffuser from Rockauto about $200 shipped and eBay $188? How's the quality and fit compared to 2017 OEM diffuser?

The 2017 diffuser is so worth it. Bolts right on and fits with most after market exhaust.

Did you have to remove the tail lights to remove the bumper as well?

Would you be able to help out on how to get this part? Or this comes with the whole bottom bumper/diffuser?

Anyone know what the cover with the bracket beneath the car trunk area that the diffuser connects to on the bottom is for? Looks like the left center bracket got bent somehow so the plastic clip won’t connect to it.
