I agree, took forever to find and one of my favorite part of the front end. It makes the front end more aggressive.

I got them done through my local auto body shop, you can buy these separate and have your loca body shop create them! you are looking at around $1K+ total for this type of body work with parts and labor; its not a cheap mod but looks great if you do through with it
You Need
1) Non F Sport Fog Lights
2) OEM/Rep F Sport Fog Covers
1. Need to cut off non f sport fog lights, cut oem/rep f sport fog covers and bondo the lights together. Once done, repaint it and have your fog covers ready.
2. Now you need to Cut your rear bumper (when placing the do cover back with the light you will see where you need to cut your bumper), once done create new attachments so its nice and tight (Body shop will know)
3. Now you can wire up your fog lights (using switch and or attach to DRL whatever you prefer)
4. Complete

Beautiful build.
Unfortunately, those are for the non-F Sport models. I actually manufacture and sell these for the F Sport (identical to what Alex has) 🙂. Please feel free to DM me on Instagram: grey_3is .

Default New Body Kit On (Modellista)




2013-2017 LexusLS460 Mirror Shell Retrofit Swap





After so long finally was able to find and get a Modellista Lexus IS ASE30 body kit in the states, mixed with Painted Grille, Fog lights and rear OEM diffuser in Gloss black, Chrome Door handle garnish and LS460 Chrome/Gloss Black mirror shell.
This kit flows so well with the 3IS model, especially with the JDM Front and Rear Tail lights.

Default Lexus RCF Frameless Mirror Install


Plug and play with Is with Rain Sensor, but it can not be tilted all the way it hits the upper plastic

Need to replace this stem with the IS OEM one due to it being longer and more adjustable vs the RC one

We need to replace the base stem from this onto the RC Frameless mirror

Side by side pictures of the rearview mirrors taken apart. Left is the RCF and the right is the 3IS mirror

Assembled the RCF mirror with the stem and Wire from the IS rearview mirror and we can see it sits correctly and works perfectly; i retain my autodim, compass and homelink features like my original mirror.
