I'm looking to outfit my 2007 LX coupe with sway bars. Has anyone tried mixing both the Eibach and Progress sways? I'm thinking of putting the Eibach on the front, and the Progress in the rear. By doing this, I would get the largest diameter of both brands for both front and rear. Has anyone done this?

-H-

 

I would say put the Si front sway bar on and then the progress rear sway. Having a larger sway bar in the back will help the car rotate. Thats what I was gonna do, cause 32mm in the front is pretty big.

 

progress rear sway ftw

 

It's official. I've now got the 32mm Eibach front sway, and the 22mm Progress rear sway. Here's how it happened. Because the Eibach kit does not support non-Si civics (you need to order their special hardware kit apparently), my mechanic made his own brackets - out of aluminum! Well... needless to say, one of the brackets shattered, and I was screwed, because it was going to take 4-6 weeks for the proper eibach hardware to come from Germany. They don't carry the kits in the US - how screwed up is that? So it was faster for me to order the Progress bar which can work on the non-Si civics. I got it on today, and love the way it feels. 3mm still can be a noticable difference. I will now also have a practically new 19mm eibach rear sway/with proper hardware for non-Si civics for sale! You can use the sway without the hardware kit on Si civics as well using factory brackets, which I now happen to have as well (I ordered them to try out as well, but the holes don't line up right on non-Si civics).

All-in-all... I'm a happy camper now Here's to the mix and match.

 

does your car have bad understeer now?

from my understanding, everyone goes with the bigger rear sway bar so that the back will kick out more and people get rid of the si front sway for lx/ex front to help correct the understeer.

 

I would say the Progress rear sway helps to drastically reduce the understeer. +5mm in thickness is a pretty big jump for sway bars.

 

I don't really know yet, PD. I'm going to be taking it out on the curves tonight to find out. It very well may, but I typically just cruise in this car; enjoying a tighter ride without being thrown from side to side. Now I do like to play a bit, and if I feel it's getting away from, I may just swap it out. I can't imagine that the extra 3mm is going to create that big of a difference, though it was noticable upon my 4.5 mile test loop. I'll let ya know tomorrow!

 

Yes it does. All other things being equal....the stiffness of a sway bar increases exponentially with increases in diameter. Granted there's really no exact formula....but it's something along those lines.

And you're going from a stock 10mm sway bar size to a 22mm rear sway bar size....which is a huge jump. The only thing that's keeping you from mad oversteer is the fact that you've also amped up your front sway bar size as well from 24mm to 32mm....which helps to balance your handling.

 

Haha what a joke you guys all are! You are talking about oversteer like these are supras or GTO's. These are front drive civics for christ's sake! I know all you guys are drift kings and you don't need rear drive cars to slide and you are busy touring on the circuit and for this I apologize....Silly ***gots. It's just silly. You talk like...."yeah dude, put a soft bar up front and a stiff one in your rear end and you'll slide around like a viper!" You guys are queer

 

3mm is a huge difference.
going off my experience with vanadium,
an 11mm bar of a vanadium can have a tensile strength of 700 lbs/ sq in.
a 14 mm bar can be up to 1200 lbs/ sq in.
but vanadium's atomic structure is cubic body centered which allows it to have that much strength.
i know aluminum isnt that strong, so it can be anywhere up to 100 lbs/ sq in or maybe even more with the difference of 3 mm

Manufactuars build understeer even into sports cars for the purpose of safety and more importantly predictability. You don't want your car to "rotate" unless you are doing donuts in a parking lot. You want your car NUETRAL not TAIL HAPPY

 

what was the point of that video?

 

Are you serious?! The guy loses control and spins out in a front drive because the car is tail happy and or set up wrong.

What do you mean what is the purpose....oh my

 

he coulda hit a patch of dirt or something.
and unless you actually know the condition of the car,
you cant say that its tail happy.

When did I ever talk like that? Please tell me. Go ahead i'll wait.

Tell me something....were you actually BORN this stupid or did your mom actually drop you on your head soo many times that she knocked some marbles loose.

STFU dude.....you come into almost every thread and act like you're some kind of big **** cause of your turbo'd car. Nobody gives a rats ***. I would figure someone as old as you would have a little more maturity than you are displaying right now. Jesus!

Nobody is promoting excessive oversteer in this thread. We're just discussing the effects of larger/smaller front and rear sway bars. Get a clue!

And believe it or not sometimes having just the right amount of stiffness in the rear of the car can help in handling and turn-in response so the car will actually corner better and maintain it's handling and not understeer right into a curb. It's not a drifting thing....it's just a handling thing. And it's about balancing understeer and oversteer to create the ideal handling characteristics!

If you're to ignorant to realize that....then GTFO and leave the rest of us who actually care about this **** and want to learn more alone!

 

"The only thing keeping you from mad oversteer"....That's what I was referring to.

Dude I'm not talking about my turbo here so why are you?

 

And that was a true statement. I'm not promoting it either. Maybe you missed that part. If you read the rest of it you'll see that I also brought up the fact that his larger front sway bar helps to balance his handling....which IS what I'm trying to promote......balanced handling....not excessive oversteer.

And you're not talking about your turbo yet....but I'm sure you'll find an excuse to work it into the next 25 threads that pop up in this forum.

You really tend to come off as an arrogant smug little **** in almost every thread you stick ur head into and calling people in this thread a "joke", "f**gots", and "queer" is way out of line and totally unnecessary given the fact that you have no justification for it and are basically accusing us of something that never happened because you were to impulsive to actually READ the f**king thread.

 

because thats all you talk about and you act like your civic is the only one that has a turbo.
im sure very many other h-t members can vouch for that.
or u can search you're own posts and see how many times you bragged about your turbo.

 

And as far as the video goes....do you even know what kind of car the cameraman is driving??

 

Yeah I read it before. I got it.

And yes, if i feel the need or it is somewhat relevant I will mention my turbo at some point.

Some advice to you all. If you are worried about understeer do not install a turbo on your car like I did. The astronomical increase in horsepower you will experience will have an adverse effect on handling by creating excessive, smoky wheelspin upon corner exit. You will understeer heavily but still stay ahead of your competitors due to the dense smoke screen

Tell me that's not relevant

 

He was driving a probe. ANd the guy in front of him didn't hit a patch of dirt....so rule that one out

 

No it's not relevant. First of all your car won't create enough power to lay out a smoke screen when cornering at moderate speeds....40/50/60mph etc.

And if you attempt to lay down a smoke screen thick enough to actually hinder the view of the person behind you....chances are you'll understeer your car right off the road. And i'll calmly pass you pointing and laughing as I do so. Either that or your excessive wheelspin will slow you down while I easily pass you up. You sound like someone who has no knowledge of the meaning of power moderation. You should look into that.

Have you even upgraded your suspension? Or does your car just go really fast in a straight line?

 

I like OP's style. Sway bars on a Lx? Why? What's the point? It's an lx. haha

It's like....aaaa dude I want to put high performance brakes and rotors on my chevy aveo....Some cars aren't supposed to be modded.
