Sway Bars
 

Anyone recommend sway bars for the GK

Don't think anyone has been able to try any bars out. Cusco I think is the only one that has a front and rear sway bar available.... Don't know if any US vendors even carry it.

I emailed Progress and they said they will have a rear sway bar available Jan/Feb for the GK.

What are the thicknesses?

Hollow or solid?

Here's a link to Cusco USA's PDF that shows the sway bars. No specs are provided, tho.

EDIT - poked around on their Japanese site, and it looks like the front is a 28mm diameter (does not say solid or hollow), and the rear is a 16mm diameter solid.

Good to hear another option is coming in a couple months… I should have my current stack of mod parts installed by then and will be ready for the next round! (c:

That rear sway looks so thin

cusco has a rear one i believe

I can't wait for the sway bars to start showing up. It seems to me they would go a long way in this car.

Bumping this thread. Anybody know if any more companies have developed a rear sway bar yet?

Bumping again! Any word on Progress or any other manufacturers?

progress or cusco that's your two choices

I called Progress about a month ago. The woman on the phone said sometime in March.

I'm thinking about making my own for the rear.

That'd be pretty cool!

Is this a sway bar?

J'S RACING GK5 FIT3 Front Lower arm bar

no not quite

No, that looks like a strut brace. It stiffens the strut towers by connecting them together under the hood.

Nope, not really.

The Front lower arm is the bar at the top of the picture.

Ultra racing is a Malaysia base company. I have their bars on my RAV4. Their product is good quality. You can see the list of suspension product for GK5 on their website

I think all the suspension bars should work on the US FIT except the Strut bar because it's for RHD. Now if you could only import them to the US. You could also bought them on eBay from Malaysia.

I personally have not get to the stage, where I want to modify the suspension yet, but if anyone would like to try it out, please let us know the result.

BTW, Honda JAZZ, HR-V and CITY shared the same suspension. You could also search for suspension parts for GM6. I believe their parts are interchangeable.

Ahh, OK. It's a chassis or control arm stiffening brace.

Here you go:

This wouldn't be hard to make at all.

I don't know about all those other braces. I have to wonder: If they stiffen up the car, how do they effect the crumple zones in the event of a crash? A race car is one thing, but a double D in the event of a crash could be something else, no?

It is quite difficult to answer your question without knowing all the fine details of the 3rd Gen Honda Fit.

But if you ask me, the short answer is it will probably not affect the crumple zone much since the bar location is closer to the passenger cabin then the beginning of the crumple zone.

The long answer is the following:

You will need to know exactly where the crumple zone of the 3rd Gen Honda FIT is located. What kind of crumple zone technology that they use and How the crumple zone operate under different circumstances. Usually, manufacture will not give out those kind of information.

If you ask the aftermarket suspension manufacture, for sure they will say it will enhance the handling of a vehicle and the bars will absolve the impact energy while collision happen. But again, you have no way to know for sure because I doubt any aftermarket suspension manufacture will provide crash data like IIHS, to compare the crash data with and without their aftermarket suspension parts.

So we could only apply the crumple zone theory in general. Therefore, anybody could have their own theory. Then it's up to you to interpret it.

In general, the crumple zone is located in the front and rear of the vehicle. For the 3rd Gen Fit, I will assume it's from the front bumper to location somewhat between the engine and the A pillar. Bear in mind that the engine itself is not a crumple material, therefore, when collision happen, the engine will be pushed back. And you don't want the engine got pushed all the way to the passenger cabin. Therefore, the crumple zone should stop somewhat around the engine area. That's why all car's passenger cabin are created to be very stiff in order to protect the passengers.
The rear, I would guess it's from the rear bumper to the rear suspension because our fuel tank is actually underneath the driver seat.

If all those assumptions are true, then when collision happen, the crumple zone should absolved most of the impact before get to the suspension bars, like the strut bar or the rear sway bar. If the bar is a quality product and not break off into pieces and fly around during collision, we should be saved.

The aftermarket manufacture will claim that the stiffness of the bars will absolve the impact energy and protect the passengers. I am always skeptical about it. It might be true, but if I am buying the suspension parts, I didn't buy it for safety.

Just got confermation that progress will be coming out with their rear sway bar by mid may
