This is from another forum but the same setup

Bought my 04 IS300 back in 2016 for $3500 to replace my daily at the time. Factory 5 Speed with LSD so it was a deal for me. Within the first month the water pump pulley failed so I did an complete tune up with new oem Toyota/Lexus parts.

It's been awhile so I don't completely remember everything.
  • The first mod I did was install a HKS Carbon ti. I also Got this for a steal because the eBay seller was closing up pretty soon.
  • Following afterwards was the Greddy Style front lip and VHT niteshaded the tails.

-Then I added the eBay TRD style sideskirts and got some new wheels. SSR GTX01s in 18x8.5 (225/40/18) and 18x9.5 (265/35/18) on some Michelin Pilot Super Sports. I believe I also picked up some black housing DEPO headlights around this time. As well as an authentic Altezza grill.

I don't have a picture on my phone of this but I picked up a HKS replica kit from ekb.plast sometime between 2017-2018. Since the factory crash bars did not fit I picked up new ones from Street Faction Engineering.

I ran the HKS kit unpainted for a few months and the following year I picked up the Monster Service V2 fender flares. I installed and painted the kit in like 5 days with some Duplicolor paint matched cans. I installed a splitter on the front bumper and sideskirts a few weeks after painting.

Car sat for 2 1/2 years because I was going to repaint the entire car but had some issues come up. I had sanded majority of the car and the body parts were stored in my garage.

November 1, 2022 I started working on the car again. I haven't taken many pictures because I forget to take progression pictures. So I'll make a sort list and update as I continue to work on it.

So far what's been done/Being Worked on
- Molded the flares onto the car
-Molding flare pieces to Bumper
  • Carbon Roof Skin
  • Custom Carbon Spoiler
  • Blacking out the rest of the interior
  • Flocking spare Dash to replace original sticky dash

Picked up some Porsche Cayenne/Volkswagen Touareg 17z calipers for $100 from one of my local junkyards. I currently have Supra TT Calipers but they don't look right with the widebody. I was waiting for this car to be put out for a week and got them right away lol. Took about 20 minutes to remove everything

I haven't decided what rotors to run and if I'll buy/make adapters. Still working on the bodywork so the calipers are not a priority.

Just a small update. Haven't done too much but it's progress. All the fenders still need alot of work and I've been fixing some cracks on the front bumper. I haven't put any bondo on the left rear flare because I'm not sure how I'll blend it in with the gas door. I kind of have an idea but I'll focus on everything else first. Spoiler is coming along as well but it's still a secret lol

Nothing too serious today. I bolted on the rest of my body parts (Still need work lol) and put on my wheel spacers to fine tune the flares for clearance issues. I'm thinking of changing wheels to something like BBS LMs or Volk Racing 21A with better sizing to eliminate the need for wheel spacers. Also a glimpse of my 17z calipers in comparison of my Supra TT calipers 馃槑

Tried to paint my 17z calipers the same burgundy/red I painted my TT calipers years ago. I don't remember exactly how I did it so they came out another color. Maybe not enough coats? I used the same Duplicolor Metalcast from before. When i freshly painted the TT calipers they matched the Altezza grill badge. This will work for now until I repaint them again

Don't pay attention to how ugly this is lol but some progress on my spoiler.I'm using my spare Altezza grill badge instead of the regular L-Lexus badge that would go here. I still need to apply filler and sand it smooth before I proceed with the next step

Not fully done with the trunk but a few steps closer. Just enough the show what spoiler it is.

ISF Wald Duckbill (Replica)

The duckbill is basically done and my next step will be skinning it with carbon fiber. I'm not sure if I'll be raising the quarter panels or extending the ends of the duckbill to hang over the sides. This is only version 1 of my project and I'll eventually make an entire truck out of carbon in the future.

Nice job! I wouldn't worry about the quarter panels though. There is that body line that swoops up to the spoiler point/edge that would be very hard to do right, if even possible. I think the spoiler itself is subtle enough while also maintaining its own curves that extensions aren't needed. Though, I say this as a guy looking at pictures online lol.
Thanks! I'll look at my options as I continue to work on everything lol. I usually have so many ideas pop up in my head but the first step for me is actually choosing what route to go lol

I'll be up in Atlanta for the holiday so the trunk will probably not be done until I get back. Skinning the trunk with carbon is gonna take a few days with coating/sanding/spraying clear or maybe more because this is my first time. I could go for the Forged carbon look because it is easier to achieve but imo it looks sloppy compared to a regular weave.

Here are some more pictures but this time in daylight

If I ever decide to get a new house a 4 car garage is definitely ideal or maybe with a separate shop built onto the property lol

The IS will be in the garage since it still has exposed bondo and metal. I'll continue to work on it once I get back and maybe I'll bring back a 1uz/3uz who knows 馃槈

Got the first layer of epoxy and laid the carbon weave on the duckbill. Added my last bit of bondo to fix the transition of the license plate cover thing. Had to transfer it inside because it was getting cold. My garage is still packed to the brim so I'm letting it cure in my guest bathroom lol

Hey, what was the process for cutting the rear fenders? One layer of metal or two? I might have to do some chopping this weekend. Lol.
I cut a arch out of the outer skin/fender first then slotted and hammered the inner skin upwards for integrity. I welded the inner skin back up, cut the excess off, and then sealed them off with fiberglass filler

Thank you. I had to get some advice before I went to hacking. Gotta clear some space to fit the low offset rears.
Take your time, measure, and mask up areas to prevent fallout on the paint (If you're repainting you can kind of skip this)

My cuts aren't 100% identical but they are close enough to fit my wheels&tires. Once I figure out what wheels I'm choosing I may/May Not have to go back in a cut some more
