Well done video! "K20 has more character. Has more soul than the 1.5 turbo". Absolutely! The last of the pure classic Civics.

[@claytondeclemente2116]

Your videos are so awesome! I’m glad you’re taking the time to document the sensible mods for the sensible car haha

[@NAUS2K]

Appreciate the comment and support bro!!

[@airyeric]

It sounds like you're loving this car more and more!

[@apjc33]

good stuff Nick! love the mods, glad to hear this one makes a big difference

[@AppleShortss]

Another awesome project I learn a lot from watching I been following for couple years now

[@cmbiker]

Wow! Great job! Seems like one of the best mods you can do for this car.

[@NAUS2K]

Puts the sport back in the trim name, this is how it should have came from the factory!

[@cmbiker]

@@NAUS2K It makes me wonder the reasoning for not doing this from the factory in the first place? Cost perhaps? I guess every penny counts in mass production. Perhaps they just think the person buying this car would prefer a plusher ride? Who knows?

[@juddosborne305]

Wow, epic vehicle. Great value for potential buyers.

[@benbryceholden1]

This is a great video. I’ll add it to the list of mods I probably won’t have the guts to do myself 😂 good work

[@nathannichols-qj2ib]

I have the same car. Recently, installed Eibach lowering springs, 27one strut bar, and Michelin Pilot Sport A/S tires. What a difference! Adheres to the road at high speeds (40 mph turns at 90mph in the rain no problem), rides and handles like a dream! Well worth it.

[@2005ep3si]

Wish you posted this video last week before I purchased and found out the Si sway bar isnt worth the effort lol. Another suspension trick I found is the 10th and 11th gen civics have a front strut "alignment pin" that can be easily removed to add some front camber. Probably adds half a degree but its free and easy

[@noahlong6638]

Try an adjustable rear swaybar! I had a Whiteline 22mm swaybar handed down to me and it does wonders

[@hai1206vn]

Great video and great mod. I love the 11th gen 2.0 6MT but still can't get over not having a real parking brake. Just one thing to correct, is that the rear spring even though 2x as stiff, is mounted at like 0.6 motion ratio. So the effective ride stiffness increase is a lot less than doubled.

[@NAUS2K]

Yes that is correct which is why I show it was 0.75” compression before and 0.5” compression after. If I said that I was just referring to the spring itself.

[@deplorable113]

I agree! I had a 2018 ex hatch, now have a 22 si. The si should have been a hatch instead of a sedan!!! But at the end of the day I love my si! I have pretty much any worthy mod. Just tuned with tsp stage 1 and the car fucking rips! I love this thing and will baby it forever! I do my own maintenance. This one is here to stay! 🤙🏼

[@deplorable113]

I have 37k miles. I have had zero issues so far. I had a few issues with the 10th gen hatch. I love my si!

[@NAUS2K]

Enjoy that Si man !!! Cheers

[@billwylde4846]

2002 to 2005 Civic Si is coming back!

[@catsspat]

Looks like another to-do-list item for me. I ordered the RPL rear engine mount yesterday, as it went on sale (Independence Day Sale).

[@NAUS2K]

Awesome , enjoy man!!

[@gerrysilva5957]

2nd!!! I just got a rear sway bar as u post this😂😭

[@CJTJBIshorts]

@@gerrysilva5957 haha

[@robtodd4726]

Nice upgrade! I have a 2023 identical to yours and just turned 31,000 miles. Zero mods, but maybe will do the intake. Waiting to see what exhaust upgrade you may do! What’s weird is I did have sticky steering and it completely went away. I honestly think it was associated with lane departure or warning. Which I always had deactivated, but the sticky steering seemed to go away on its own.

[@DivRogue]

You should try the skunk2 shift knob with the acuity boot collar. It’s a weighty knob so the shifting is buttery smooth. It also looks great and blends with the interior of the the car really well

[@NAUS2K]

I’ll keep it in mind thanks! I daily drove a skunk 2 knob back in the day. I will say I do love the oem leather knob. Who knows maybe I’m getting old 😂

[@MrSmith804]

You should definitely try the Ktuner 1.2 or the 2.0 and see how the car behaved after the upgrades, since you have the intake that would give you at least 26 to 30hp.

[@dailycivicsi9295]

I'm still waiting for a supercharger install lol

[@user-mf8lg4fz9l]

Nice video！ This video helped me a lot! Could you please share the OME Suspension and springs part number of si?

[@Steven-kc7id]

Do you plan on installing an exhaust, Ktuner or PRL upgraded shifter bushings?

[@ValkenDnB]

Are you going to do the acuity shift kit? The base bushing, shifter bushings, rocker arm, shifter spring, etc.

[@ValkenDnB]

Si sway bar or type r sway bar next?

[@zerrrep]

ahhh the cvt removes the character!!!!

[@jodirt2k7]

Is it possible for si springs to fit on a 10th gen hatchback sport?

[@jaymingles]

Awesome! Are you eventually gonna change out the sway bar or no? I got one from sirimoto and it made a big difference. Although I'm not sure that it's worth it after swapping over to Si springs since you've already eliminated a lot of body roll and the car is decently stiff already. Could be that any more stiffness in the rear would make it slide a lot more in wet weather or on gravel which isn't great for a daily.

[@NAUS2K]

I’m may consider it in the future if I do take it to an autocross and what not. I am really happy with how it sits now though

[@Moondoggy1941]

Should not a "air quote" Sport model have "air quote" Sport model suspension?

[@NAUS2K]

Yes, this is how it should have came from the factory!

[@Moondoggy1941]

@@NAUS2K Yeah an upgraded suspension.

[@jamienewsom3944]

What would be the likely outcome if you were to swap out just coils and not the shocks?

[@NAUS2K]

Shocks are tuned to work with a specific spring rate. If you just swapped the springs and left the stock struts it would be under-dampened or over dampened. Not sure how big the difference is or how noticeable it would be, but this is the right way to do it

[@ryanluu7661]

how much did you pay for the si suspension?

[@NAUS2K]

$180 , mentioned it during the pov review

[@CJTJBIshorts]

Firsttt! Also 3 minutes ago

[@NAUS2K]

My man!!!

[@Locallybuiltauto]

Funny enough the HPD civic hatchback uses the Si suspension from factory

[@NAUS2K]

No it does not. The HPD kit does not change the suspension. It’s only visual

[@Locallybuiltauto]

I wasnt aware of that. Ive driven both cars and i find it very similar. Thanks for the info!​ @NAUS2K

[@Moondoggy1941]

Question for the fans of Honda. Buy a brand new Honda Civic Sport 6 Spd MT or a Acura CPO RDX A Spec app. price 31 to 33K PS I am retired but not that retired.

[@s13gouf60]

If you can still handle getting in and out of the civic it wins hands down. Just rolled over 14k on mine and absolutely love it for daily duty. Comfortable seats, good ac, reasonable visibility, butter transmission, revy engine, a better stereo than my 9th gen si, and as close to basic as one can get these days. Still has lots of tech if you're interested; car play, Bluetooth, active cruise, lane departure, ect. It gets great mpg, I'm bumping 40 mpg highway if you can keep your foot out of it. Very easy to get to most standard maintenance parts. I will complain about the lower shield being a bit of a pain to remove for oil changes. Far easier than my 9th gen, to work on, probably on par with my 5th gen.

[@samsung40_media87]

nth!! who cares!?

[@nickclashez]

Looks like wasted money and time lol
