So first and foremost it seems as if RPF1s don’t fit on the accord X? Is this correct? I have 18x8.5 +40 RPF1s and would like to use them on the accord X if I get it.

Second main question. I inherited a snowmobile and trailer from my father who passed away and I’ve read they can tow 1000lbs. The snowmobile weighs just under 500. Trailer looks maybe 200-300lbs. Anyone have experience with towing with these cars? Do they hold up well and tow decent?

Mods would be ktuner. Fmic. Downpipe. Flex fuel and then upgraded turbo or a 40 shot of nitrous. Would the car be able to handle those mods?

after owning a civic X and having the stock clutch slip just after doing the Ktuner 23psi basemap I wanna make sure my next car can handle the upgrades.

First off, welcome to the forum. Hope you get some help making your decision. As far as the wheels I don't see why something as common as RPF's wouldn't fit. that isn't a very extreme set up. Can I ask why you think they won't fit?

Towing-no clue, can't help there

I can say you shouldn't have a problem pushing those mods, the fastest AccordX's are all 10AT guys. Most running bigger turbos and some on spray.

The 10AT is pretty stout from what I see and even the manual (which I have in my 2.0t) holds up well. I traded a CivicX Si to get my Accord and never had clutch slip even on TSP stage 1. My Accord has been tuned on Ktuner stage 2 for nearly 10k miles and has given me 0 problems, engine or tranny. Pheable.net has their "stage 3" tune that came out recently that pushes the car beyond 300whp and 360wtq which is offered via the ktuner platform. So if you want to go fast and have less worries than your CivicX clutch then join the club.

Hope this helps!

RPF1s only go up to 18” and the accord is 19s so I’m assuming they won’t clear the caliper? I haven’t found a single accord X on RPF1s I’m wondering if that’s why. I’m just torn between white or black the dealer has a white 18 and a black 19. 200$ price difference. Similar mileage. I’d prefer white cuz less heat issues in the cabin in summer but the black is sexy as ****. Yeah I’d do Ktuner and flex fuel ASAP. Then eventually FBO and probably small nitrous shot.

My 2019 EXL had 17's stock and IIRC it has the same brakes as the Sport and Touring. If that's true, I THINK you should be good with those 18's (I'm running 18" Konig Ampliforms on mine now)...
right on. Maybe I won’t sell them then. Being 18s is there some tire calculator I can use so I can run the correct tire size without any issues?

Yeah, other trims use 17's and 18's. another member @Bluez_cluez just lowered his and put it on 18x8.5's so check out his in the link

if you want to go flex fuel get that all together and look at Phearable.net for their flex fuel tune. They have one ready to go if you're not going to do a custom tune.

This is for your speedometer:


For fitment, you kinda have to take some clearance measurements for your stock set up and compare with what you are planning/hoping

For sure gonna run the phearable flex fuel tune.

so probably astupid question. Ktuner and flex fuel kit. Can I just throw 93 in it let’s say in winter when I’m not gonna be blasting on it. Then a few gallons of E85 to give it the blend whenever I wanna have some more power and the tune will adjust accordingly? Or do I always have to run the E30 blend (or whatever it is I’ve seen E30-E-40)

I would recommend asking the guys at Phearable about that. If anything you might be able to just reflash to a base Ktuner map and run that then flash back to flex when you're ready to run it.

There are a few guys running RFP1’s, just not on here. 18x9.5 +45 offset seems to be the size most run with a 255/45/18
Phearable Stage 3 is 93 and the Stage 4 is flex fuel tune. Keep an eye on the Ethanol levels with the KTuner V2 or Tuner View.
The Stage 3 Tune is 93+ octane tune. So adding a gallon of E85 gives it a lil boost without a flex fuel kit.

Check it out my dudes. 2021 2.0T 10AT once the engine is past 600 miles I’ll be doing the k tuner stage 2. Then within a month flex fuel and stage 4. Going to wrap my RPF1s in drag radials up front and idk what tire I’ll run in the rear. Then saving up for the stage 2 CTR turbo

Congrats!!! And welcome to the club. I had a 2017 4dr Si on Hondata Stage 2. It was fun but the Accord is just nicer. Also had a 2017 CTR but had to let that gem go when we had our 6th kiddo. Needed at least 5 seats.
