looks pretty good, would it fit if you have the gfx rear lip?

 

those look terrible on the regular IS IMO

 

hmmm... seems like the edge isn't aligned well and quite a few silver bolts were nailed in. It looks ok to me, will think about it.

 

rather just get a whole new rear that has a diffuser, like tom's or ings or something. not my cup of tea

 

+1 on that. Sorry just not my cup of tea. Does not flow at all.

 

Looks realli nice

 

This is just a prototype fellas The final fitment will be later this week and have all black screws and more work to get it to sit perfectly....patience!


aznpapaya: We would be happy to do a free fitment on an ISx50 with the GRX rear since I'd like to know how it fits too.


thanks for the comments and critics!

 

Me next!

 

a diffuser is supposed to be a performance aid so i have a question: wind tunnel tested? any type of testing?

 

Looks better on the IS-F. This is because we all know that a diffuser is a performance item, and an IS 250 isn't that performance like.

 

I like! I think this will look sweet on a light colored IS since the black plastic of the diffuser will flow with the black plastic at the bottom of a stock '09+ bumper.

 

They look like those roof spikes you see on STI's, but on the ***. I think it's too much for a classy car.

 

Funny... just saw an EVO with those stupid spikes on roof. No way in hell i'm getting these for my IS.

 

EVO's came like that stock

 

i think i saw this car just now on bayshore/101 sb. was the diffuser on? if so, for whatever it's worth, the piece is very subtle in real life. car looks good.
