DIY gurney flap on my evo viii wing.

Got this ebay "M3 style trunk lip" a while back.
cut it, double side tape to my wing.
Made a gurney flap.
It was a fun project.
Yes, the car is filthy, but I for 1 out of 100, I drive my evo DD. I dont store it. EVER.

enjoy.


BEFORE 3 MONTHS AGO:




NOW:
gonna NOT stay wingless anymore. I tried both. I really really really like the wing. I dont care about harrasement/cops anymore. I just want to enjoy the car for myself.














have a good holiday guys. dont drink(too much) and drive.

Looks great on the wing. Have you experimented a gurney flap underneath the wing. While the wing is on the trunk?

FYI peoples wings have snapped with the gurney flaps on them. Too much downforce on the wing itself. I think they were 9's though, they have hollow wings; the 8's wing is filled with foam i believe to give it more rigidity

First time I've heard this. Do you have any additional info?

I have a Gurney flap and haven't split my wing yet going over 130mph on track.



OP, did you move your M3 lip to your wing? Looks good, should give quite a bit of downforce.

thanks guys. yeah. i moved that piece from my wingless trunk to the top of my wing.

and yes the evo 8's wing is filled with foam. I"ve gone only as fast as 90mph so far and its still holding lol.

and yes. it should give quite a bit of downforce at $0 (already paid for it months ago).



well Texas cops are more lenient. but I drive like a grandma and maintain my evo to the best of i can. I rarely speed and i sometimes get impatient ppl flashing their highbeams at me to go faster. I just let them pass then i flash my highbeams back at them 20x longer.

as a matter of fact. I was so pissed off at this lexus suv rx450 for highbeaming me cause i was going slow due to a stalled vehicle on the very rightside of the road, I tailed that SUV and flashed the heck back at him. he then got scared and pulled into a gas station. afraid that i was gonna follow him to his house.

eitherway. back to topic. thanks guys.

Yes the issue with wings breaking in half was an evo 9 issue.
I just ordered the Rexpeed gurney flap. I will have to see how it matches up to yours.
I ordered the white one. if i dont while the white on the CF i might give your idea a try.
