so each car will require custom spoilers right¿i mean you cannot just remove the spoiler of one car and plant it on another right¿

Yup, unless a spoiler is tested in a wind tunnel or on a reliable software with it being fitted onto a car, it's nothing more than an ornamental object (which may work for you........ or against you).

Ok this makes me ask this question:

How many of the spoilers(company provided or 3rd party) that we see on our cars(extra fitting) are calculated ?

Atleast in India, where the same type of aftermarket spoiler does duty on so many cars, it can't possibly be helping them.

Even though aftermarket spoilers don't really create lift, there is a chance that it might be seriously affecting the flow of air at the rear, creating unwanted turbulance/drag which can affect high speed handling and top speed.

What about the spoilers provided By Honda for City & Mitsubishi for Lancers ?

I doubt even those are aerodynamically caliberated to the car.

But, i'm pretty sure the Lancer Evolutions or the Honda NSXs would have been tested aerodynamically.

9 out of 10 lancers have a spoiler. Though some are cr@p.

Why isn't JD with an EVO VI having a spoiler for his car ? ???

That's bcoz

1. It isn't a Evo VI but a normal Indian Lancer with an Evo engine and drivetrain.

2. You don't really need a spoiler for a 13 sec quarter mile. Spoiler causes downforce which is the equivalent of adding weight to the car.

3. As long as you're going in a straight line, on a flat surface, you don't really need a spoiler, unless you're doing insane speeds.

Folks, I need your inputs. I have a week old Civic(polished metal) which has won an accessory package in Honda fest. So I would be getting the Elegance package + rear spoiler(the one with lights). 1) I dont know if rear spoiler looks good on Civic (haven't seen many in B'lore), 2) Is it really functional ? If not, I'll drop it and probably ask for something else, if thats possible.

Front spoiler can help. Esp by routing air into the engine compartment. Also, clear up turbulence.

Rear boot lid spoilers in sedans are primarily decorative. There is too much turbulent air in this area. They will be much more useful if put on top in the rear (as in some hatches).

Any car which moves faster than 100 Mph requires a spoiler for stability. Speeds less than that do not require one unless you need a sporty look.

@ Vabdan
exactly , the width of the spoiler and height at which it needs to be mounted need to be calculated, since how the air flowing above the car need to be diffused and where the vortex is formed is needed to be known.
