[Epoustouflant]

I've documented my unboxing and launched an intro special here.

Bumping this one up. Any installed picts yet? Thoughts? Thx!

Here's some pictures from our customers! Everyone liked it so far and most commented on how easy the install was especially with the instructions and necessary hardware already provided.

wanted to share some picture and some notes regarding my install. this is a pretty complete product. everything lines up as it should. a lot of nuts and bolts included as well as some riveted pieces which certainly make the install easier.
definitely easier to take the wheels off when doing this. i did this on the floor, i imagine on a lift this is a cakewalk. took me about 1-1.5 hours. doing this again, i could probably do this in 20 minutes (yes, that simple)
i personally feel that in the instructions, when it asks you mock-fit the rear to make the holes for the front, i would also suggest you mockfit the 2 screws on the side. this attaches the undertray to the front lower fender liner and the bumper, although seeing the pictures above, the bumper above doesn't extend whereas mine does. i have an '06. kind of odd that the bumper mounting is different.
overall, i'm happy with everything and with the track season coming soon, we will see how this affects the cooling (pow3r says it improves it)

how effective is that hole for the "venturi" effect? Also not that it matters to me but might to some, doesnt that add lift? Similar to 997 911s with adding a third radiator. the air exits to the bottom versus the top like the GT3.

Ordered one of these, looks like a nice piece and my 20 year old plastic shield is in shambles

These undertrays are designed to withstand increased levels of protection, and reduce oil temps while on track. The rubber trim on the undertrays cooling aperture seals onto the OEM plastic cooling shroud, drawing heat away from the oil cooler through the effects of venturi.

What is supporting data for reducing oil temps? What conditions, what car setup, how many degrees?

What is the increased level of protection for? What are we protecting from?

Was there any aerodynamic testing done? This part is flat, there is a reason why stock plastic tray is not...
