Does the Sport model have more downfore the the base model?
Does the Sport's body kit and spoiler create better handling at the high speed?

 

I doubt that there is any real benefit from the body kit on the sport. The spoiler may keep the rear window a little cleaner. I will guess that it is mostly for looks. I don't really know anything though. It does add extra weight which adds to downforce.

 

To my understanding, i dont think downforce is really an issue for a normal streetcar. The difference between sport and non-sport models because of their kits is probably immeasurable at the speeds we travel.

 

The Fit Sport bodykit and wing are purely aesthetic. Any performance increase/decrease is neglible.

 

There may be some tangible stability benefits near the Fits top speed, that is, if the body kit actually produces smoother airflow.

There rear spoiler isn't really big enough nor is it shaped to produce any downforce. But it does increase drag, however.

Most spoilers on sports cars like the F1 cars are upside-down wings. So that instead of lifting the car, it pushes the car downwards. If you just have a piece of sloped board, that's not a spoiler, that's a wind-catcher.

 

The other thing with downforce, you have to get up to "extra-legal" speeds to start to see it really have an affect on any car. That's why many Porsches, and the Crossfire to give two examples, use retractable spoilers that only elevate at speeds usually somewhere in the 80 mph range---give or take. Unless the owner wants to show off, of course. There are also buttons to manually elevate the spoilers.

Besides, they also cause drag, slowing the car. Example--the Lamborghini Countach with the $3000 spoiler has a lower top speed than one without.

 

I bet this J's Racing Carbon 3D GT-WING should help downfore cos is so big

I'd say it probably helps at the very minimum. I would need to drive a base to confirm if there's any different between the two.

You guys think Honda wind tunnel test the OEM body kit?

 

yep. i think it's asthetic. the spoiler isn't even shaped like a true spoiler (whcih is literally an upside down wing)

 

And in a front wheel drive car, downforce on the back end is just about completely useless.

 

You'e clearly never run an off camber sweeper at 110 mph in an FF+ at
full suspension loading. I used to track my ITR and even with the factory
wing it got a little loose at Buttonwillow at the rear and would come out on you if you pushed it too hard. Switching to a GT Wing
fixed all that.

 

Wow, that's pretty interesting. Never heard of that before. That would be an interesting sight to see, haha.

I doubt that the stock wing does much. If you want downforce, go with an adjustable GT wing so you can set the angles and stuff.

 

Not directly related to downforce but...
Can't remember which big car mag. did a test of various wings and spoilers and found that all of the wings slowed the car down but nearly any front lip spoiler helped top speed and stability. They also said that a rear wing has to be carefully shaped with extensive wind tunnel testing in order to produce real downforce.

I wonder if the Fit Sport rear 'wing' could produce slightly more downforce at speed just by effectively increasing the area/length of the roof?
