I'm aware that the Sport has 16x6 alloy wheels and has a stiffer torsion beam, and has a slightly wider tire at 185 width vs 175 for the Base modem, but this seems to FAIL to account for how much more fun the Sport is compared to the base: the Sport suspension feels more taught, I think there are more suspension differences

I get the feeling that the Sport shocks and springs are tuned differently too, could this be true?

I just don't believe that the wheels and RSB account for the differences.

I bought the Base, I should have gotten the sport.

 

Dampers are the same.

The tire width isn’t important but the extra inch of wheel diameter likely removes some squish from the steering. Different tires may also contribute.

Your car may also just be more worn out and in need of maintenance

 

You may very well be right but this comparison was done between several cars (not only my Base and a Fit Sport.)

Still, you may be right. My next step would be installing a Tein Street Basis Coilover (or Bilstein B14.)

I'm exploring the possibilty of adding a Progress RSB (but that seems like snake oil more than anyhthing else)

 

I can second Street Basis' coils, I have a set on my Miata and plan on getting them for my Fit. At their pricepoint and performance they're perfect for a street car that just needs to sit a little lower and have a little less body roll.

 

I want a lot les Body roll to be honest...... are you comparing the Street Basis to the Fit Sport or the Base

 

Sorry, I'm comparing how they changed my Miata. However I like them enough to consider buying them for my Fit Sport as they're a nice alternative to lowering springs. However I don't think there's a difference between the base/sport Fit's suspension.

Edit: Shocks are the same between base/sport. PN for a FR shock on both models is 51611-TK6-A02, same with the left shock, rear shocks and all springs.

 

1000% not snake oil, difference is night and day. Makes the nose pointier, more confidence inspiring to throw it into turns.

 

Wow. MANY people are saying this!

I think I might just go for it, it's not that expensive.

Here's the thing: on my 2007 Corolla (which I lowered on Bilstein B12) adding the thicker TRD rear anti-sway bar to replace the stock one sandwiched inside the torsion beam MADE ABSOLUTELY NO DIFFERENCE for me. So that's why I'm skeptical but in the Honda Fit's case, it MIGHT be different----the rear might just be loosy goosy enough to need tightening up? ?

 

You could try CR-Z springs and shocks like i did, and have best of both worlds.It was a accidental discovery. But worked like a charm. Cheap,stiffer,Bolton and OEM Honda reliablity. Check this out and you will be surprised.

Thanks for the suggest, I was not aware this is possible-----my BIGGEST COMPLAINT ABOUT THE STOCK BASE SUSPENSION IS THE LOOSY-GOOSY MOTION-----I WANT THE MOVEMENTS TO BE WELL-CONTROLLED (JUST LIKE MY 2007 COROLLA.)

I'm going to look into the CR-Z parts now.. I like what you wrote: I guess I won't be getting stock CR-Z parts if I go that route, I will be going for aftermarket stock-like replacements.

Are CR-Z parts just bolt-ons or require modification?

 

boltons. Even the K-Swap mounts are same etc etc. All these, CR-Z, Fit, Honda insight are very similar.

 

I've gotten under my base model and looked thoroughly. There's no rear anti-roll bar on mine. Might be worth a look for you.

 

This is correct: there is only the rear torsion beam which acts as a anti-roll bar as well.

The sport model I believe has re-inforcements there.

I find myself in a bit of disbelieve that this thing is "TWISTING" and that it's twisting so much as to degrade the ride of the Base----- I mean if that were the case, HONDA would've just spent an extra 1 dollar to make it stronger (that would be a no brainer.)

I'm not sure the Progress bar would make a difference, tbh.

 

Mine has absolutely no linkage connecting the rear suspension Not sure if its that way for others, but I seriously got up IN there. Its non-existent. not routed around the underside of the spare compartment, just nothin there. Picked up mine used with 35k miles on it from a dealership. No mods or indications of being messed with.

​​​​​​People on here swear by the progress bar. Id say if you've got nothin out back like myself, it should make a big diff

Edit: sorry, i got like, zero sleep and get what you mean about the torsion bar. I think having a secondary bar with an offset mounting position could do a lot :s but i'm more interested in the crz suspension swap now.

 

I've had my '09 since new, had something like 96k miles on it when the bar went on. Night and day is the only way I can describe it. Highway stability is much improved, overall confidence in corner entry is much higher. It makes a bigass difference, basically.

 

Ditto the results with our GD Fit.

The stock beam doesn't twist...it bends and flexes. The bar acts to stiffen the weak rear beam and makes a noticeable improvement. Don't think of it as a sway bar. Think of it as a chassis stiffener for the rear.

 

You know what: you both are knowledgeable and credible. I'm going to go with you.

The reason I'm skeptical is because the TRD RSB on my 2007 Corolla made no difference BUT this is a different car!!!!!!

The progress bar is only 170 bucks shipped on EBAY so I'm going to get it, what could it hurt?

 

I also very much enjoy my RSB bar. Is it night and day, no. But it is an improvement from without it!

 

Low profile tyres can make a big difference in performance and road feel. Higher profile tyres can be more comfortable and compliant.
