I can look in our CAD of the car and see what we can do there.

Now that is a technical answer!

I can tell you that on the Viper GTLM and GTD/3 cars, we tucked the wheel house as close to the tire as possible. Basically we ran the tire thru full bump/droop, and lock to lock, then added an inch or so to that envelope. Rules dictated where we could put "exhaust cooling", so that's where the opening and screen went, and the air vented out the side cove. We couldn't use ducting, since it was cooling air. The GTD/3 got additional venting, via the louvers in the top of the fender.

It looks like there is plenty of room in the fender to make a duct(i would exit out of the fender thingy on the side). You could make a quick mold by using high density foam and cutting to the shape you want. After you have the shape, clean it up and make sure it has some draft. Then make it out of fiberglass or carbon. Won't be hard but won't be easy either

@zdr93523 - I hope you didn't take my response personally. I just couldn't resist. The idea does intrigue me though.

Never do. It was funny and actually more technical albeit ridiculous.

Can anyone with more experience tell me if I'm wasting my money on this?

That maybe the case but that would mean that the main spoiler is so freakin' huge it doesn't fit in the frame of the photo!!

This Password:JDM spoiler looks very interesting to me, I've never seen anything like it. It's a GT wing without lifters, and with a pretty severe gurney flap on the tail end. Does this look like an effective spoiler to you guys?

Also, I can't tell for the life of me how wide it is. Messes with your eyes...

just finished reading the whole thread, really nice, but in the end, nothing really came out of it, not product available or no conclusion to what woud be ideal for our cars?

any drawing or pictures of what would be the ideal wing or diffuser for our car? Same for front lip or are there things that can be improved on?

what do you guys think of the box on the Griffon where it takes the air out of the rad and sends it through the hood vents?
