do-it-yourself diffusor

[alverman]

Here's an idea for a diffusor I made for myself last winter. It also works like a kind of undertray, it has cutouts where one cat would be too close to it - it's fiberglass - and the engine rear support is, it can be moved up or down for more or less clearance at the back of the car and pivots at the front. There were no issues after months of use.
Next winter diffusor project will be one that goes from the left to the right fender under the exhausts. The photos may not be too clear, as you can see, I'm not a photographer.:wink:

Looks good, can't wait to see next winters version. BTW, what exhaust are you running?

 

[alverman]

Thanks, the exhaust is custom made.

Nice work !

Ever think of cutting rear bumper cover of the fake diffuser (black) w/ a hot wire and then replacing w/ a bonafide diffuser? You could sell them if you had. Good luck !

 

[alverman]

Good idea. It happens the second diffuser I am working on now will incorporate a third element shaped just like the original two you suggest cutting. This because I want to be able to go back to original any time.

Actually I consider his to be a "real" diffuser if it does the job. Excellent work BTW. That closely resembles the GT-One diffuser.

Can you make one for 02 rear ends? If so I will buy one of you.

Any pics on how you made it

 

[alverman]

I only have pictures of the finished one.
But the new one is coming along nicely :smile:

 

[alverman]

Here is a picture of the second diffusor. After winter as promised :biggrin:
It has a third centre element just as the two original ones on the nsx and goes all the way from left to right under the exhausts. The outer right and left fins are detachable and this one also can be altered in height from the ground, but that also changes the gap between the diffusor and the car.
It is easy removable for going back to original.
May be an idea for anyone who likes it ?

That looks very good.

That looks great. And it makes me think I should really paint my diffuser black, even though it still wouldn't look as good as yours.
