Lexus RC F

After driving the VR-4 for 25 years, I needed to search for a replacement.  In terms of very high performance coupes with four seats, there are of course the American ponies and some European models.  In the end, I bought a 2015 RC F for the large displacement engine and the loud body contours.  It was a leftover from the previous year and was available at a good price.

March 2016
Test drove and bought the Shark.  Named by my daughter due to the fin on top and the side gill vents.  I was originally only going to test drive this particular car, but they offered to allow me to take it home for the week.  Well after driving it a few days, I was completely hooked on how it felt and resolved to buy it.

May 2016 - PPF
First mod was to wrap the front of the hood, grill and side fenders with Suntek Paint Protection Film.  This particular type is designed to use the heat of the Sun to remove slighy hazing and scratch marks.  I bought the film on Ebay (vendor "mykodesigns".  I also received my NASA plates this month (visible in images below).

Suntek PPF wrap on the hood.  You can see the faint line to the right of the hood scoop.

I was able to do a good job on most parts even though it was my first time wrapping a car.  However, the complex front end with the head lights was a challenge, and I could only wrap it by doing it in sections.  I do have a seam right at the sharp edged running light.  I tried again in 2017, but still could not do it in one section.  

July 2016 - First Ceramic Coat
I used the 22PLE Ceramic coat for this first go around.  It took four hours to do this job, and the main time demand was the buffing of the paint to correct any flaws in the finish.

August 2016 - Red Calipers
I decided to paint my brake calipers red by using high temperature paint and clear.  Since they are Brembos, I obtained some high-temp decals from an Ebay vendor.

2019 Update.  The paint has not faded in the three years since.  When I added a small touchup to repair a nick, the color was the same.

October 2016 - Dash Cam
I decided to select a dash cam that would allow me to mount it in the grill.  I didn't want a movable device cluttering up the cabin.

Dash Cam integrated into the grill.

There is a large fuse box in the front driver side corner of the engine compartment.  I found a switched feed and plugged into that for power.

October 2016 - Embroidered Patch
After some searching, I realized that no one made an RC F patch.  I worked with the online vendor The Studio.  They had the best price and did not charge me an increase despite the changes I made at the last minute.

Patch that was designed and custom made.  Note the
matching red DashMat that fits the Lexus RC.

January 2017 - LED interior lights
These are for example the trunk, door and interior lights.  From Ebay vendor jdmautohaus.

April 2017 - Aero Kit
I like the low wide look.  But instead of actually lowering the car with after market springs, I decided to add a ground effects kit.  The kit includes a very aggresive splitter lip, the side skirts and the rear spats.  I installed this system myself without adhesives so that it can be easily removed, cleaned, buffed, etc.  The kit was from CF500 in Boca Raton, FL.

In the year after (2018) I removed the sideskirts and filled them with expanding foam from the bottom followed by black rubber spray.  Due to the carbon fiber material, I found them to be a bit too flexibly, and the foam added stiffness and rigidity.

June 2017 - Aruba Rocks! Apparel Sponsorship
Working with the company CEO, I added decals for several photo shoots in return for apparel (active wear, hats, etc) for the family.  

April 2018 - LED lights
I installed LED bulbs into my reverse lights.  Rated for 1600 Lumens from  Also installed projector lights in the door as shown below.

June 2018 - Borla Exhaust
The 5 Liter V8 is one of the reasons that I selected the RC F.  However, I find its stock exhaust to be we way too quiet.  From the tests others have done, a HP increase of about 20 hp is expected.   This brings my system to 485 hp range.

Installation of the Borla took two hours of labor.

With the system installed, I would get infrequent Check Engine Lights with the P0430 Code.  A post on the Facebook group recommended the replacement of the exhaust gaskets (which were reused from the stock ones).  This was done in Jan 2019, and I will update this page if I get any more CELs.

Driving the car now with the paddle shifters is really much better with the Borla.  I can make the car growl and pop on downshifts.  It is just so fun and almost like playing a musical instrument.

July 2018 - Second round of ceramic coat
The ceramic coat I applied last year is only rated for one year.  So I reapplied, but this time the 22PLE VX2 PRO version.  This is expected to last several years.

August 2018
- Clearcoat of Caliper Bridge Bolts
Although the calipers themselves are nicely painted (red), the large bolts that tie the halves of the caliper together are just bare steel and they corrode to a dirty red color.  I removed them, buffed and then clearcoated them with high temperature clear paint.

Clearcoated (and washed) bolts on the caliper.

December 2018 - Lexon Rear Wing Extenders
As loud as the styling on this car is, I think the rear wing is a bit understated.  Even though it does move up and down with the speed, I decided to add on the Lexon Wing Extenders.  I think it looks much better now.

January 2019 - RR Racing Heat Shield
This intake mod was added from RR Racing and is good for 10 hp, bringing the system to 495 hp.

February 2019 - Carbon F logo
Also from RR Racing, this replaces the large "L" on the grill with a carbon fiber "F".  The manufacturer suggests glueing this into the grill with black silicone adhesive but I wanted to do something reversible.  I also wanted to mimic the illuminated star accessories that some Benz's have.  Since I already use the Neopixel addressable RGB LEDs for my other hobbies, I decided to use these here also.

Preliminary installation of the F logo.  The left image shows my concept
for a removable installation.

The logo is made removable by using a 1/4" plexiglass panel that is about 6"x8".  At the top I used two #6 bolts into the original mounting holes of the OEM L logo.  The thickness of this plastic allows the bottom to be wedged into a slot in the bumper.  I then drilled small pilot holes into the back of the carbon logo and used self tapping screws to screw it to this plexiglass panel.

goes to a Flora Arduino compatible microprocessor.

Translucent white plastic bonded to the F logo with silicone adhesive.  At the
top is the "Add-a-Circuit" tap that allows me to get both switched and
unswitched power from the fuse box.

The flora controller is powered from an unswitched source in the fuse box, and has an input to monitor a switched line.  When the car is not running a red 'heart-beat' pattern runs.  As soon as the car start event is detected, a white animation runs that spins while the car starts up.  It then stays on white while the car runs.  See below for a video.
