The Cusco Type RS is an awesome LSD. They can be noisy/chatter when the transmission is cold, but once warmed up and with the correct fluid they are silent and work fantastic

09/19/26 Update:
Installed this week:
HRC TCR wing from JAS
The HRC TCR wing from JAS has been sitting in my garage for over a month. I wanted to wait to install until I had the Racebred front splitter. It was expected to arrive this week so I went ahead and installed the HRC wing last weekend.
Removing the factor wing is straightforward. The only potential issue is losing a bolt or washer inside the rear hatch trim. I knew this going in from a few YouTube videos so used a magnet and avoided the issue.
The HRC wing doesn’t come with any instructions but installation is simple. Where the OEM risers mount OVER the top of the painted hatch surface, the HRC risers mount IN the hole in the hatch. The HRC wing does not include any weather seal and the OEM Honda seal wouldn’t be helpful because of the difference in mount.
To ensure the mount would be weather sealed I purchased some 1.5” wide, 5/8” thick foam strips with 3M tape on one side. I then cut them to the correct shape and melted them down to match the mating surface between the HRC wing and the hatch.
After mounting I then added a thin layer of silicon to ensure there would be no chance of any water intrusion.
EVS rear tow hook
The OEM rear tow hook is disappointing and inexcusable (as is the lack of front tow hook) for this type of car.
The OEM hook is short enough that you have to remove the cover completely to mount it. The cover is much larger than the tow hook shaft so you‘re left with an unsightly opening in the bumper when the hook is mounted.
I purchased the EVS rear tow hook with the intent to cut a hole through the cover to allow the tow hook to stay mounted with the cover in place.
The EVS hook is just slightly too short to make this simple. Because it’s slightly too short, the hole in the cover has to be larger than it would be if the tow hook shaft was about 0.5-1” longer. Either way, once installed it looks pretty good.
Racebred front splitter
I purchased a 5 inch Racebred front splitter kit, with diffuser tunnels and the new CFRP end plates.
I do not have any front lip so the Racebred kit is mounted to the OEM bumper.
I chose to have my local shop do this install because of the amount of work required.
Js Racing Valve Cover
While the car was in the shop I had them install the Js Racing valve cover. It looks great.
PWR WOT radiator and transmission cooler
My original PWR WOT radiator system failed, with a cracked core. PWR replaced system for me and I’ve had it sitting waiting to install until the Racebred system arrived. This avoided tearing apart the front end twice.
Driving Impressions:
When I installed the HRC rear wing, I drove about 30 miles between city and highway. At speeds above around 60 MPH, the car felt a bit unstable compared to the OEM setup.
It wasn’t anything drastic, but was noticeable. The balance was upset by having only the rear wing and its additional downforce.
Since installing the Racebred system, I’ve driven about 50 miles of mixed city and highway. The car feels PLANTED. It feels like it should have come this way from the factory.
My first track day with the new setup is tomorrow 09/20 so I’ll report back with a more detailed assessment of the impact of proper front and rear aero. Rain is forecast so it will be interesting.
