Im going to start my F Sport bumper & grille conversion (upper and lower grille) very soon. I want to put together a parts list for the conversion and have the experts go over it. This is my first Lexus so im new to the brand. Also another thing that worries me is that i have parking sensors and headlight washers. Can i just simply swap it into the F Sport bumper or would i have to cut or drill any type of holes?

I tried searching the forum for a DIY on the 4GS and couldnt find any but i did see a few members mention to get new headlight washer caps? Not sure why i cant reuse my existing washer caps. Removing the bumper will probably a no brainer but ive never worked on cars with parking sensors or headlight washers so i dont want to break anything lol.

Parts List

F Sport Bumper
F Sport Upper Grille
F Sport Lower Grille
F Sport Tow Hook Cover
JDM Foglight Bezel - Optional if you have OEM USDM foglights
USDM Blank Foglight Bezels - No foglights

Now the next part of my questions...will i need additional clip or screws since im converting the bumper and both upper and lower grilles? Can i retain the fender liners or would i have to get new ones (not sure if theyre the same or not) Any help is appreciated and maybe this thread can get sticky for future references since this is a simple job and can be done without going to the dealer.

There are at least eight GS front bumper covers in total:

• Standard bumper (no sensors, no headlight washers)
• Standard bumper (sensors, no headlight washers)
• Standard bumper (no sensors, headlight washers)
• Standard bumper (sensors, headlight washers)

• F Sport bumper (no sensors, no headlight washers)
• F Sport bumper (sensors, no headlight washers)
• F Sport bumper (no sensors, headlight washers)
• F Sport bumper (sensors, headlight washers)

On Sewell's website, I see a separate listing between AWD and RWD as well, but I don't recall if the body shop I used had to consider that.

If I am able to recall correctly, I needed to purchase the following parts:

• F Sport front bumper cover
• F Sport front bumper cover tow hook cover panel
• F Sport fog light bezels (JDM)
• F Sport lower grille
• F Sport upper grille

The front badge and upper grille chrome surround are the same between standard and F Sport models. I asked if there were any fender liner or underbody cover panel differences between the models and I was told there were not.

I have the following parts left over:

• Standard fog light chrome bezels
• Standard fog light trim fillers panels
• Standard upper grille
• Standard lower grille

My front bumper cover was destroyed due to a collision.

I also had the rear lower valance replaced with the F Sport model's. It is identical to the standard model's with the exception of the color, which is a gloss graphite. This matches the standard and F Sport model's gloss graphite upper grille. I was told that installation required that the rear bumper cover be removed.

thank you for your feedback i had no idea the tow hook cover plat different until i called the dealer today. Yes they do make multiple bumpers so you have to get the one that suits your car best.

did you do the front end conversion yourself or did the dealer do it?

I had a body shop perform the swap during a collision repair. I know about the tow hook cover since that part was not ordered with the front bumper cover which caused a delay of a few days.

I am going to have a body shop do the swap for me, How will you paint the bumper yourself, if im not mistaken they come in raw plastic and there is quite a bit of body work involved.

You will need the air ducts on both side of the lower grill as well.

I've seen the bumper cover in "raw" form. It's plain urethane which requires sanding and other preparation.

Vizzy

Does the air ducts serve any purpose on the F Sport? Wondering if I can get away without the air ducts

redjdm

You can probably don't fit them but they guide air into the front wheel area for brake cooling purose. I guess it's optional but I did bought and installed them anyways.

Yeah we did the conversion, it was very simple. We did order the bumper with headlight washers and the little washer pieces were back-ordered so it took longer to install than we planned.

Everything fit like a glove and we did use the fog lamps, it was plug and play.



Then we added the fog lamps

Can't wait to do the conversion. Ill be ordering the parts this week

Also can anyone give me any tips on removing the parking sensors and headlight washers? I don't wanna break anything when I convert the bumper

The standard bumper includes those ducts as well, they just aren't as prominent in the bumper's styling. Are they differently shaped on the F Sport?

LexusVet

what do the tow hook covers look like?

Vizzy

The tow hook cover is the plastic piece on the driver side of the bumper it's kind of square shape. Right below the tip of the grille on the driver side

Super old thread I know, I just didn't want to start another thread on something similar. So im looking to order parts for my conversion and I noticed others talking about ordering air ducts? I dont recall reading about needing those in the other front end conversion threads. Can someone who has completed the conversion please confirm whether or not we need them? Thanks!
