Your Mods To 2006-2011 FD Civics

[buzz]

how much did that set you back? looks nice tho... very clean

you most definitely right about making the aero dynamics better and reducing the air traps...

good stuff

[ej20i]

ahhhh...but was it worth it with the amount of money u spent on it?

[Havocwreaker]

If it seriously reduces noise, then you really can't put a definitive value on that. DMX might really appreciate a quiet drive. But I don't think the fuel consumption figures will tumble.

Yeh, it'll be good to know how much noise reduction it really does vs. the cost.

I appreciate a quiet drive too

On the topic of ride comfort... Does anyone know which spring gives the best ride in terms of comfort (not concern about track) ? Cause I find the stock suspension abit too stiff to my liking.

Read in a Euro thread (and other forums) that the Tein Comfort Sport coilovers gives a very comfort ride:

Just wondering if there're other cheaper options...

well, i got them with cost price (i mean got with 1st hand price from honda japan) and it was 3months ago when AUD 0.90+ USD.
i can tell you, it's under 300AUD to arrive here.
and don't talk about mod right now, our AUD already R.I.P and also YEN rise up very high, so we get double impact

The main purpose is not noise reduction, but for reducing drag or air trap under the car to get better aero. noise reduction only side effect
if you really want noise reduction, just get sound deading, much more effective and you can tell the diff. straight away

I really don't believe it's a significant increase in drag reduction, that's all. Sure there are a heap of odd shapes and cavities underneath the car but smoothing all of that out won't really lower your coefficient of drag.
Even if you get air trapped in the nooks and crannies underneath the stagnant pockets of air they produce would be negligable compared to what you'd get off the back of the car.

let me share

There really aren't too many areas to improve the CD of an f-body,but the one area that needs the most help is almost always ignored:the undercarriage.Look under an NSX,911,or rear engine Ferrari and you see a smooth undercarriage-no exhaust pipes,driveshafts...etc.This is the reason why these cars have high top speeds with modest hp.The only way to improve aerodynamics of the undercarriage on a street car is to use "belly pans".Belly pans smooth air under the car,decreasing drag and improving top speed(usually).

http://media.gm.com/intl/opel/en/new...elease_698.htm
The following changes were made to cut aerodynamic drag still further: the Corsa Sport's roof spoiler and side skirts were adopted along with large-diameter wheel covers that guide the air flow smoothly past the wheels. An undercarriage panel improves air flow underneath the Corsa, and the size of the cooling air ducts was reduced so that less air flows through the engine compartment.

It's interesting to see the airflow passing from the side of the car to its underneath area - despite the wide side sill panel. This flow may be promoted by the Porsche's flat undertray.

The 993 twin turbo has a factory quoted Cd = 0.34 which is a quite good for a car that also sticks to the road at high speed. The drag coefficient probably benefits substantially from the car's full-length flat undertray.

http://www.autospeed.com/cms/A_108676/article.html
Rather than letting the air that has passed through the radiator simply spill out from the engine bay, here an undertray with specific exhausts has been used. The air is guided to emerge from two openings in the tray, whereupon it again accelerates in speed. Note the slower speed in the wake behind the car.

FYI. New Hybrid camry which backed by Aus federal Gov
Every line and angle of the Camry is aerodynamically honed - reaching a pinnacle with Camry Hybrid's 0.27 coefficient of drag - while Camry SE employs Toyota's F1 technology on the undercarriage for enhanced stability at higher speeds.

so what's a solution that's both practical, simple, and doesn't make Betty ugly? I'm thinking about modding the UNDER SIDE of the car with an underbelly tray anyways... why not build a ferrari-like undertray?

physics lessons yo...hahahha

[parraboi]

lol i believe all the cars dmz mentioned above were twice as fast as the civic... thats why our civic didnt come with the underbody cover stock... whats the point for a shopping grabber??

All civic in Japan comes with this stuff, and Aussie Hybrid which only 85kw also have this

hey...wif the fuel of price...any drag reducer is better than none
