pelan chiao drive ratio?
final drive?

ohh.. diff terms.. we call it final drive ratio lo. if not mistaken 4.3 .. later i got on laptop update

can get more hp ar...

i got the whole excel build to calculate that jo geh.. in my lappy.. whatever wheelsize u masuk it will tell u what speed at wat rpm

what you mean by frontal?

Speed at 3,000 RPM ...

1st Gear - 24.05155775

in KM/h

U mean the grill area?

To be frank i saw yoru question and have totally no idea what you were refering to

So smaller or bigger better?

There's a tradeoff, bigger grill opening = more cooling more drag, smaller grill opening = less cooling but less drag

Wah lau.... kua chiong....

If you are concern with drag coefficiency of the car (usually comes in after 160~180kmh) then u should invest into folding side mirror...

Anyway.. its redundant.. cause there is little if any mods u can do to increase the coefficiency ....

Geez.... we still talking about a mid size sedan car ah?

Koolric, I think only Mitsu fellas know the frontal measuring area but given that info, what can you derive from it?

It is not so simple as to know the area in feet/inch/mm; the shape of the corresponding body area, the angle of slant, the curve of the bonnet, headlamps, windscreen, frontal openings (grill - lower & upper), the roof, the under carriage and the tail end boot all adds up the 0.29cd (sure so low ah?). Changing a little here or there may reduce drag here but adds drag there.

Yes, adding a spoiler at rear will induce more drag but introduce more downforce. It depends on your driving style if u need more frontal or rear downforce. Anyhow, our car will not achieve such speed where modding a few fins/spoiler/mods will achieve any substantial better fc or increase in measureable speed.

We could go on and on with this, but lets not be too critical about our cars. Cheers!

*RANT STARTS*

Drag Coefficient? Bleergh. The car can't even crack 300kmh and you guys are worried about drag.

In all seriousness. You think adding a couple of fins and wings here and there is gonna change things much? On a road going (sometimes if perasan go into track) car?

Not unless you're planning to drive 180 ALL THE TIME.

And performance mods? Well, it's a family compact car (or so the Westerners say), how much "performance" do you plan to wring out of it? Without turning it into an unreliable mess?

Good luck anyway.

Oh if you don't enjoy the TCSS, you're in the wrong car club lol.

*RANT OVER*

Chabutzzz...
