Default DIY - Rear Sub-Frame Brace

Well I thought I would document the progress of design for a rear sub-frame brace.


I have pre-liminary locations for the LCA Bolts, and the Sway Bar mounting locations. Next step is to cut a part and check fitment on the car. I will post more info and more drawings as dimensions are considered more accurate.



You may remember discussion about this DIY from this thread, which was a DIY for sway bar braces

Never heard of that...

I figured it was CAD because that's what I'm going to school for...drafting

Looks cool though

Wow I'm going to bookmark this! If your EG subframe brace goes into production, I might have to splurge on some! You can ship to Canada right?

Curious to know why you need those 4 blank spaces or the horizontal beam? If you don't have those 4 spaces empty, wouldn't that help on strength of the whole frame?

you might need to thicken up everything by .250 +/- .250, and use longer M10 bolts. A design like this will kink under hard pressure where the outter ovals are.

Unless this is for bling, you dont want any stretching.

has this been tested, and all the dimensions in the drawing are correct to give this drawing to a laser cutter to get it made?

holy $h!t, resurection from the grave. I havent posted anything about this for a year!

Yes, I have been running this on my civic now for the last year, and the part is awsome.

I made it out of 1" thick aluminum, and the 1/2" thick brace is more than stiff enough. I also love the fact that my rear sway (19 mm) is located off my sub frame brace (no more worries). If you want to know that abuse I put it through, I Rallycross about 1 a month, and have also done 1 autocross, and 1 track day at Miller Motor Sports park. I also drive this car 70 round trip to work and back. It is holding up beautifully!

If you want one, I can make one for about $160...let me know!

Wow, back from the archives!

Could not say, I have never ran an ASR brace. That is why I made my own!

Sorry, this was a home grown project. And I do not have access to an EK for development!

Those spaces have been removed from the acutal brace. If you want to check the actual brace thread (finished product) go here: https://honda-tech.com/zerothread?id=2139492

And yes it has been tested, read earlier in the thread.
