Just installed a JT-Designs Undertray
 
Basically this thing goes under the front bumper and replaces the plastic undertray with an aluminum one. Lots of people have lost their plastic ones on the street (including me) and this is a stronger alternative, and I can't see it falling off anytime soon.

At least this way i don't have to worry about debris coming up and slamming onto a rad hose or something, plus it keeps a lot of air from coming into the engine bay from the bottom of the car.

I had to make a couple cuts along the front edge due to my non-OEM bumper cover, but it fits.

Now:

This is what the underpanel itself looks like

By the way, these are not my pictures, I don't have a digital camera (yet), but at least you get the idea.

And Kirasir, no I haven't forgotten, msg me about this when you can.

Damn, that looks pretty sweet!
I need something like this cause the plastic piece on my car is being held with some home made stuff. Where and how much?

Group buy from M3 Motorworks back in December for like $110US shipped.

Nelson,

How much do they charge directly from their website? There's no info listed there. Did you feel any difference in terms of airflow under the car at higher speeds?

I was looking at the AC Schnitzer one as well which was similar to this design, only they had a rear diffuser under the rear of the car as well for downforce. I always wanted something like this, just never knew where to find one. The 318's never came with any kind of plastic cover for the bottom, so this is a good investment for 318 owners. I assume it should bolt right up to the OEM M3 front?

Thanks,

Bryan

Who's website? JT-Designs or M3 Motorwerks?

I don't drive my car in the winter so I don't know about the airflow thing, but even then I don't think it'll make such a difference that I can feel. Next time I go to the wind tunnel I'll run the smoke stream by it and see if it smoothened the air under the car. I don't think it matters to me much mostly because I don't track my car to the point where .001 seconds matters.:P

AC Schnitzer one costs an arm and a leg does it not?

The JT-D underpanel was made for the M3 bumper and the non-M bumper as well, so you'll have no problem fitting it.

I think the main reason for JT-D designing this was for people who were sick of losing their stock plastic ones constantly, and to offer a little more protection from road debris. That is why I bought it.
