I am the owner of a 2015 Honda Fit EX with a 6 speed manual. I bought it with only 400 miles on it in 2017 and now with nearly 50,000 miles on it I want to make some modifications but I "want my cake and eat it too".
What performance mods would you suggest that:
1) wont make gas mileage worse
2) wont sacrifice comfort
3) wont make driving more dangerous
4) MOST IMPORTANT dollar per smile ie) What Mods that have the greatest return on the dollar spent?
Where I live in Arizona cars are NOT smogged tested
Please share your thoughts on the below mods with the above things in mind
Cold air Intake
Aftermarket Exhaust
Turbo
Suspension
Brakes
Sound Insulation
Suspension
Any others??

 

I have clutch master swap with an old civic one. Crz mugenstyle intake, xtros throttle controller, rota wheels, short shift adapter, ik22 sparks, had ecu remapped,, main cat delete,, epman trev manifold breather

 

Cold air Intake - Increases intake engine noise, that's about it.
Aftermarket Exhaust - Increases exhaust engine noises, that's about it.
Turbo - Now we can get some extra power. How much money do you want to spend? Reliability could suffer. MPG could go down. Do you have another vehicle? Tuner near by?
Suspension - This is where the Fit shines. You can make it look great and handle better. Check out TEIN for comfort coil overs but most will make the ride firmer.
Brakes - These are always a nice upgrade. A better set of pads and maybe rotors will help
Sound Insulation - Absolutely, the Fit is a bit noisy
Wheels - Add a set of lightweight wheels to help keep the Fit nimble on it's feet.

Best dollar per smile is up to what you like. For me suspension mods and keeping it looking nice did it.

 

No modifications improve performance and comfort. Leave the car stock.

 

Surprised nobody has said a rear sway yet, there's a bunch of us here who have the Progress version and think it's great. I didn't like the amount of body roll in corners stock, or the amount of understeer with stock suspension. Both are dramatically reduced if you put the rear bar on, it doesn't require any cutting or other permanent modification of the car, and you can put it on with a pair of jackstands and a socket set. Best of all, it's cheap.

If you want more power, you should probably go the opposite of the way I did, and get a ktuner. I got the RV6 downpipe and put a different muffler on, and I like the result, but probably minimal real hp gains. Although the ktuner isn't exactly going to transform the car, either.

 

Get a CVT. Better mileage, better performance. Paddle shifters make some attempt to mimic the fun of gear shifting.
Just joking, I couldn't resist.


Light wheels and tires...

1. made mileage better by 10 to 20% plus one stat I read said 40lbs off your wheels and tires is like taking 400 lbs out of the car for 0-60 times.
2. improved ride AND handling, plus made the car much more quiet in the cabin.
3. improved wet, dry and snow traction
4. cost me just $85 out of pocket for new wheels AND new tires

I plan on doing some sound deadening as well. I will do a modest sound system upgrade at the same time.

Finally, I've been told that Orange Fury is the fastest color, but I pretty much bought the car because it impresses women.

 

Wheels don't have anywhere near that effect.

 

What effect?

 

10-20% increase in fuel economy or 'removing 400# pounds'

I've owned around 30 sets of wheels. Ranging from the extremely light (Volk TE37, Racing Hart CP035) to the not so light (Panasports G7 C5C2). I've never seen a real difference in fuel efficiency between wheels and if anyone would see that difference, it'd be me, I've got hundreds of thousands of miles tracked.

 

Also comes down to sizing (particularly width) and tire compounds. No hypermiler will rock an 8-inch TE37 on Star Specs.

When I went from steel wheels to my current wheels, I noticed at most a 2 mpg increase, and that's probably a stretch. Same tires too. Driving experience was a different story.

 

I literally mounted RPF1 on the same tires I had on my OEM wheels. Fuel economy was unchanged.

When I swapped from my OEM wheels on my S2000 (16x6.5/16x7.5 with 205/225 tires) to Advan RGIII (17X9 with 255/40 tires), again I saw no decrease in numbers. Unless my driving is extraordinary a lot of this is hyperbole

 

Every car and every driver is different.

The little Fit engine needs all it can. There is a reason why hybrid models of cars have small light wheels.

I noticed a change in MPG with heavy wheels on the Fit, not so much in the GTI.

 

If you'd read my linked review, you'd have seen that the mileage increase I have gained may be due to a combination of factors.
As far as 0-60 times, the one fairly objective test I have read showed nearly 1/2 second improvement in 0-60 times by running wheels that saved 10 lbs per corner. And of course there are physics involved.

While I understand the power of confirmation bias, I can say with some level of certainty that road noise at freeway speeds has been significantly reduced.

In any respect, while I do understand that you are quite ready to make braggadocios claims about how much more you know than anyone else and why, you'll have to forgive me, for in the limited number of posts from you that I have read, it appears to me that any claims you make should be taken with a high degree of skepticism. But thanks for your input, nonetheless.

 

Hybrid models of cars generally don't have light wheels. Toyota Prius C comes stock on steel wheels, not light. Prius comes on big full face wheels, steelies, etc., not light. My Fiesta sFe (the 1.0l I3) came on steel wheels.

But yeah, the Fit would definitely be more impacted by super heavy wheels than light ones. That said, Enkei RPF1 are one of the lightest wheels that are widely obtainable and they did zilch for my fuel economy.

In the 10 fill-ups before I mounted the RPF1 (on the same tires that were on my OEM wheels) I got between 39.96 and 42.86 MPG. In the first 10 fill-ups with them I got between 37.69 and 41.05 MPG. I'm the only one who drives my car, my commute did not change in that time period, the RPF1 did nothing to encourage "pushing" the car because I was on the same tires & a much more fun car was parked next to it for those purposes.

Freeway noise = You went with different tires of a totally different brand & model. Also new tires are generally quieter.

As for 0-60 time....that can be chalked up to any number of circumstances. Conditions, air temperature, driver inputs, the fuel in the car, even the device you're using to 'measure' it, etc.

BTW, your fuel economy gains could probably be caused by your decision to run your tires at 25 PSI. That's worsens the handling, that's super wasteful on fuel, etc.

Running your tires at the proper pressures will make more difference than some low end cast wheels (or even high end nice wheels).

 

Yes, I said I bought quieter tires. Did you read what I wrote?
Again, I said an objective test, not my personal experience or testing. Did you read what I wrote?
I don't run my tires at 25psi. (except on very rare occasions on certain types of dirt roads where it improves ride and handling). I'm running 37-34 psi. Did you read what I wrote?

I don't need $1600 wheels for my Honda Fit. I don't think it wise that we respond to each other's posts any longer. I don't have any interest in your "advice."

Good day, sir.

 

I weighed stock wheels and my rota wider 6.5inches wheels with 185 60 tires and got only a 1 kilogram decrease,, aftermarket wheels that starts at 6.5 wide size and tires makes it as heavy as stock as well

Was about to change the stock reserve wheel to rota as well but the minimal weight decrease discouraged me to do so

 

my fav mod was light weight wheels. reduction in unsprung weight per corner made the car "Feel Faster". being that I can achieve 40 mpg consistently, I would say these helped my cause. As far as comfort goes, I guess certain tires can accomplish that.... but I have no useful input on that one. Dollar per smile = I think this does the trick
