THAT SHIRT! That just made my night, getting caught back up on your videos. Time to get to work on my own fleet, always love to see what you're up too.
Yup, gotta rock it on the garage whenever I can! Likewise man, I always check in on you too!
Every time I run into a problem with my EF I think to myself if Garage Built Hondas has a video on it. Sure enough he does😂
Glad you got that sorted. Can't wait to see the difference with the seat, harnesses, new alignment setup and coilovers!
I welded 1" x 1/8" straps across the front and back along with a few reinforcements on the top of my front subframe and strategic seam welding. I also added reinforcement to the rear crossmember using 1.5" straps on the bottom, rear and outer part of the LCA pickup point. Cracks on both are quite common on the EF chassis with sticky tires.
The Honed roll center correction is a game changer. It removes so much of the snap oversteer and makes the rear of the car work entirely different. Worth the cost.
Watching your videos makes me want a crx or Hatchback project . Thank you brother .keep it coming 🤙🏼
The extended balljoint fixes Roll Center, that lowering messes up. The subframe bar did all the Caster. Both are important.
I use smaller bars and harder springs for street and winter use, and put on bigger bars for track use with stickier tires. DA bars are a great upgrade and lighter than the stock solid one. Thats also why they stick out further because of the crimp.
Never had interference issues with my radius rods on stock or innovative front setup tho on any of my bars.
Good stuff man.
If the subframe crack again, TIG welding some material around bolt holes might be a solution. Just like every drift driver do to their rear subframe.
You do see a significant improvement!
Well done Jon. Looking forward to the next track event footage or well anything really.
🙏
Nice video I Love my Honda Civic 1989, saludos cordiales, y todos aquellos que apreciamos esta linea de vehiculos.
Thank you!
Another Great video!!!
Man that reminds me what I had to go through
Not a lot of fun.
Saludo desde PR 🇵🇷🇵🇷🇵🇷💪🏽💪🏽💪🏽💪🏽💪🏽🔥🔥🔥🔥yo tengo un CRX también 💪🏽🔥
Good video like always 🙌
👍
I cracked my subframe in half in 90 Si with cheap coilovers. Was still available to purchase from Honda in 2008
👍
Very informative as always!!! Thanks!!!
I also didn’t have any clearance issues with my crossmember. Must be from the integra da sway bar
Thanks for the add homie!
🔥🔥🔥🔥
👍👍
Amazing
👍
ours has the same crack almost same spot but opposite sides.
That's no fun!
Great video as always. I do find myself confused by the cracked cross member as others have stated. How exactly does this happen? I see “cheap coilovers” mentioned…..but there has to be more to
It than that.
Stiffer suspension, stickier tires, heavy abuse, and stiffer motor mounts.
Great work as always! Now I want to take a look at mine lol. I did have a question about something that's off topic, are the EF sedan and hatchbacks filler neck tubes the same? The hose that connects the filler neck to the gas tank. The one I had was cracked and I want to try to find a replacement.
That's a good question. My guess is no, only because hatch vs sedan and the rear seats are different. I could be wrong though.
@@GarageBuiltHondas they are completely different lol a sedan hit the yard a couple days after I had asked.
This is the first suspention cross frame I have ever seen cracked on any Honda. What causes this. High track loads? As always your work is precise and well don't. I know of the rear honed correction pieces your talking about. I just think there's not much advantage to them and the price they are selling them for is rediculous.
I was thinking the same thing!
I had one crack back in 2008 in 90 Si with b18a engine and cheap coilovers. Think the heavy front end, manual steering and body twist did it. Mine was cracked in half going front to rear.
@@hondafreak8613 man that's crazy😬
I've seen cracked subframe before. It was the only thing not yet reinforced in a caged, spot welded car with over 450,000km.
In a FWD car, the majority of the lateral force is transferred through the front lower control arms. On the EF, these pickup points are on the front subframe which also supports the rear engine mount and steering rack. This puts three different loads on the subframe at the same time. With most swaps, only the rear engine mount is retained thus all the engine torque is transferred through the subframe. Wider, stickier tires also increase the lateral load. These different loads concentrate at stress points which exceed the limits of the material. You can either widen the stress points by plating them, such as the rear motor mount holes or distribute the load better into the chassis by adding plating to span the crossmember which reduces the loads at the stress points. Generally a combination of both is the best option.
Basically everything you do to make the car faster, either in the turns or straights, is asking more of the front crossmember which was designed for 100HP and 185 tread width tires.
This issue is because you are using DA knucles, this knucles has a different ball joint possition , i have same issue on my 90 REX.... But car feels fine.
I only see this problem on usdm cars, also the pedal assembly seems to snap. Is it the climate causes rust? Poor quality?
Great video btw.
I ususally only see it on rusty, slammed or crashed cars. But thats most of em now. :-/
I had a similar problem with my 91 civic ended up buying crx crossmember but it didint fit so now I have an extra subframe
It should've fit. Both of my extra cross members were from EF civic hatchbacks. They are all interchangeable.
@@GarageBuiltHondas it fit but the steering joint would not line up with the civic rack
Do you think damaged or cracked subframe can also cause negative camber on front wheel? I got negative camber on the front left wheel on my 94 Civic Coupe. I replaced all suspension parts and I still can't find a cause for negative camber. Thanks for you videos.
Absolutely, I'd slide underneath and take a look at it. The EG also has the compliance arm? ruclips.net/video/07KqnP3BKWY/видео.html
@@GarageBuiltHondas Yes it does have compliance arm if I'm not mistaken.
@@GarageBuiltHondas I'm trying to think how a compliance arm can affect camber(toe).
In that video you can see mine was bent and only visibility when removed. You may have a similar issue.
Can you make a video reviewing the federal RSRR? I'm interested due to the price but I'm not sure if they're any good
What are you going to use them for?
@@GarageBuiltHondas I track my ej1 quite a bit on a 2.5 mile course local to me. I have used mainly falken tires previously
These are a step below the RT615 and 2 below the 660. They're cheaper and will last a decent life but you lose grip.
@@GarageBuiltHondas I kind of figured as much. I ended up getting a set of slightly used re71r for a good price today to finish out the season
My 90 civic gets a weird vibration it’s only noticeable while driving on the freeway and car compresses on the dips , and under heavy left turns hub bearings are good, tie rods seem fine everything seems to be in working order any suggestions?
Make sure your wheels are balanced possibly
@@sillycrow123 Thanks for your input! I’ll let you know if this is the issue.
What front knuckle/ spindle are u using on the crx? I notice an abs ring on the outer cv joint
DA
@@GarageBuiltHondas ok great thx for the info
What happens when the junk yard no longer has stuff like those subframes?
I found some parts on offerup someone posted a parts car and asked if they had the subframe then they shipped it to my house
Where are you guys finding parts nowadays? I can't find anything
Same
Like?
@@GarageBuiltHondas Bulk head piece that sits on the top of the firewall. Bottom of front windshield is glued to it. When you remove the dashboard it is essentially the metal that is left behind. I've been looking for any EF to cut a new one out but I can't find any in FL, GA, or AL. I don't want to buy a whole car though.
So, does the Innovative traction bar give you a caster adjustment? If so, I have to get one.
Btw, Justin (that guy you rode around with, with the tan CRX) had the same issue with the radius rod rubbing his sway bar. He ad it in one of his videos. I think a innovative did a 2nd rev on those.
It does. 👍
@@GarageBuiltHondas thanks! Just ordered one.
