Your “solutions” (91 or 93 octane, and a dealer visit) are ridiculous if you haven’t simply checked your actual gallons used and miles driven. Fill up. Drive 100 miles. Fill up again. See gallons required to fill up. Divide. Adjust driving as needed. Problem solved.
Also “I never rev above 3k.”...
Where is the coolant temperature reading taken? Is there any risk it’s being influenced by the spray but the actual temp is higher away from the sensor?
Example would be in a home if the thermostat is in a closed room, temps can be regulated in that room but not the rest of the home without...
I was thinking KW offered the V4 Clubsport kit for the FL5. Is that not the case? I had it on my list of potential future mods, with a price in my notes.
I'll be installing a J's Racing carbon hood in a month or two when it arrives. I'll have a Championship White available at that point if you're still interested. I'm in NE so would require shipping. I'll likely post to the classifieds when it's available.
07/18/26 Update:
Verus canards installed. These are very nice quality carbon fiber and install very solidly with 3M tape.
HRC TCR wing arrived and I’ll hopefully install this week.
Nankang CRS tires ordered.
Next track day is 07/26.
I don’t have any experience with the EBC RP-X pads, but I have run Paragon R3 on the front and rear. I’m now running Ferodo DS1.11 front/rear with the AP Racing Radical calipers up front and OEM calipers in the rear. The Ferodo are an improvement over the Paragon on track. They are too noisy on...
07/13/26 Update:
I completed another track day at I29 Speedway on 07/12/26.
It was a very hot and humid day with temps peaking in the upper 80s and humidity at 60-75%. In the morning, when it was 75-80F, I was on 91 octane and fuel map and was able to reach top speed of around 122MPH. In the...
07/11/26 Update:
I installed SRP Racing Pedals today. I’ve had them for about an month and hadn’t gotten around to installing due to lack of time and very hot weather leading to a very hot garage.
Installation is straightforward.
Dead pedal - drill four 7/64 holes and then install the SRP...
I think the AP Racing setup is about as good as it gets. They are very consistent and the 9668 kit has 25mm brake pads so they last a lot longer than any pads on the stock rotors/calipers...
Hey I’m glad you did cooling first! The RV6 rear sway bar with billet end links seems like a good quality kit and price is not bad at all.
I recently added AP Racing front rotors and calipers with Ferodo pads and stainless lines. I drive exclusively with pedal dance so my rear brakes see little...
I have a lot of track days on my FL5. About half were with the OEM suspension module, and about half are with the ITS module.
I notice no real difference in understeer or turn-in with both set-ups in +R mode. The big difference, and reason for going with the ITS module is the lack of control...
Shut off torque vectoring when tracking. Front pads will be destroyed unless you go to an aftermarket track ready set.
Two seconds is a lot, depending on the track, and it’s more dependent on the driver. There are huge differences between Type R and SI that none of your listed mods address.
For the track you need to consider the modification costs in your budget. Type R needs at minimum: brake fluid, brake pads, negative front camber, radiator, oil cooler.
You said it’s primarily for track so you’re going to need those.
06/26 update
06/26/26 Track Day at I29 Speedway
We ran a private track day with 10 people today. I spent a lot of time driving and riding in other cars. I put in 31 hot laps and another handful of cool-down laps that I didn't log.
I was only able to run 91 octane and my 91 fuel map so I was...
Agreed on the wasted money and time. I’m going to accept this is part of tracking cars unfortunately.
I do notice a difference in temperatures between the OEM, the PWR track spec, and the PWR WOT triple pass spec radiators.
I’ve run all three with HEL oil cooler. I’ve run the track spec and...
I wouldn’t say PWR products are lacking in quality based upon one report of failure. My intercooler and track spec radiator are working fine without issue.
I could not find any information on other Civic owners with PWR issues.
If I have any further issues I’ll certainly update but I don’t...
06/25/26 update
PWR WOT Triple Pass Radiator
I shipped the radiator back to PWR and they confirmed it was a failed core. Jason at WOT has been great throughout the situation, working with me and PWR to set up the return. He also refunded me the cost of shipping back to PWR.
Once the failed...
I’ve been waiting for some time for the front splitter and wing. They have said coming soon so expect something this year. I am not interested in increased rear downforce without balancing the front (Ie the AOA kit).
