There are multiple empty hole in the subframe. Its easy to miss the right ones. I have a hard time believing there is one model of civic with a subframe that has a different manufacturing process. Why would they go through the trouble of not putting threads on just the EX? Not saying you are wrong. Just doesnt seem logical to me
You can't really be saying I'm wrong anyway, I'm pointing out another member couldn't mount the brace because his holes weren't threaded. Whether or not he was mounting it in the correct holes has nothing to do with me.

I have done the Type R subframe brace and Rear sway bar. Made a noticeable difference on the track. Less body roll and a little more oversteer. I have a Type R RMM I want to install, which will hopefully help with wheel hop/traction. I know it won't be a huge difference, but I do not want a ton of vibration.
Would it fit on a Hatchback Sport?

You think everything could fit in from a 2018 Type R?

Front Strut Bar
Rear sway bar
Subframe Bracing
RMM
Rear sway bar - yes
Subframe brace - yes
RMM - yes
Front strut bar - Type R doesn't come with one. I recommend the Ultra Racing or DC Sports one piece bars.

Lol. Read the entire 11 pages on the other thread trying to find this info and thanks to @jacobegg for mentioning it.

Good to know, thank you. When you do replace the stock Eagles, you may want to pony up for the Michelin Pilot Sport 4S summer tires. I did and noticed a huge difference in grip, which was already pretty strong. Also wet traction was much, much better as well. Of course if it snows in OK you're out of luck, or drops below freezing...
...not a common occurrence here in this part of AZ.
Those tires are awesome. I have them in 235/35ZR19

Everytime the topic of modifying ones car comes up (especially tuning) our community seems split into two groups: 1.those who mod 2. Those who think its moronic to do so.

To start the Year off right i thought i should post about a mod i figured both groups could get behind!

I have subframe bracing on my 9th gen and it makes a world of difference. Even before i bought my new Si i was researching subframe bracing assuming the new 10th gen would benefit from it as well, i soon learned the new chassis was way stiffer stock for stock. It caught my eye that the Type R came with a subframe brace stock. But i stopped researching assuming the new chassis would be enough.

After owning the 10th gen a few days, i was amazed. The new chassis was miles ahead of the previous gen. I couldnt get that Type R subframe brace out of my head. Not because i necessarily thought the car needed it, but because there was no real review of it on a Si and if Honda has it on the Type R it must do something, right? It was 38$ and $4 for the bolts so i caved and bought one.

Install was a breeze, thanks @jacobegg for the extra set of hands!

I immediately felt a difference coming out of my bumpy neighborhood road. The pot holes and bumps where much more pronounced, the car seemed less forgiving in that sense. I immediately got on the freeway and drove 1 mile to the nearest 180° highway exit. The results where awesome

This brace shined at highspeed sweeping turns. It didnt increase corning speed like maybe a sway bar would. It doesnt increase the "limit" of the car. It does, however, make finding the limit and riding it much easier. The car felt settled much sooner during turn in and made holding a line much less work. Its such a confidence booster when approaching turns. It almost makes turning on these stock eagle all seasons fun!

For a OEM piece that cost under $50 im blown away. I hope someone finds this helpful and i wish you all and your families a happy new year!
What torque did you use. Imagine 60ft lbs?
