Hi all. I will remove my evo IX spoiler and then i will take Rexpeed Type-C Carbon Fiber Trunk Spoiler. But i am worry about the aerodynami.
if i do this replacement does it make negative aerodynami?

Thanks.

 

just got it, very good quality. Aerodynamically i would assume it would provide some good downforce without being to restrictive...but i am not a expert

 

Unless you track the car i wouldn't worry about aerodynamics.

 

pics?

 

It will provide less downforce than the stock wing, but unless you're going over 120 mph, it should not be very noticeable. There are things you could do to offset the loss of rear downforce, such as getting a rear undertray and/or installing a vortex generator.

i alredy have vortex generator.
and on highway i drive about 200kph.

 

i am no expert but....

Downforce is drag, drag is less mpg.

 

It will give you some downforce, but not as much as the stock wing. If you don't track your car that much or tend to drive 100mph daily, then I wouldn't worry about it. The only negative thing I can think of is less downforce than the stock wing.

Then I'd get a rear undertray to go with it. Should make the car feel more planted at speed, since, among other things, it eliminates the parachute effect of the rear bumper. You gas mileage at that speed should go up too.

not this.

thanks for the answers.
which undertray do you suggest ?

 

i have the rexspeed spoiler on my car, feels the same + i can now see easily out the rear now!

high wing only provides downforce on speeds above 100+

 

Since Vishnu doesn't make theirs anymore, I'd probably go with the APR rear undertray.
