Underside panels.
 

Okay I've got some panels under my car that cover quite a bit. From trying to crawl under there, I can see the exhaust and the engine pretty good but there are panels that cover the sides between the front and rear wheels. There is also a vented type of panel in the center. They also cover most of the chassis brace.

How I discovered them was when I went to the dealership on unrelated business. I had looked under my car to look at the sway bar with my dealer and he noticed the panels. At that moment he called them 'skid plates' and I had from then on referred it as that. He was pretty surprised that they were there and really didn't understand why I had them. The service dept was closed at the time and so he couldn't ask anyone else.

I know they really aren't SKID plates because it's not an off road car. I had asked another member here about them and he sent me a diagram of panels that he told me were designed to help with noise and smooth out the air flow underneath.

The diagram and his explanation made sense but from what I can see the position of the panels don't match the position of the diagram he sent me.

I noticed that no other car on the dealer lot had them except for a 2010 IS-F.

Does anyone else have these under their car?

Can anyone explain this to me please?

Maybe pics would help? Sorry about them being upside down, I rotated them on Photobucket but don't know why they are still like this. Just turn your head. :D

1. Center, slightly back from front wheels.

2. Between front and rear wheels, under doors.

3. Between rear wheels. This may not be a panel, because of the shape?

4. I think this is from back of the car toward front.

I wish they can be further back so you can see more but I tried to crawl under there and ended up just sticking my arm out and snapping randomly.

Those underbody panels are designed to reduce wind noise. The '09+ 2IS's have more panels than the '06-'08

I dont have them :(

good find ...
I guess your lucky to have them.

they collect dirt :egads: i remember taking one out while changing oil and had plenty of dirt only after 3000 miles :thumbdn: Try hittin it and if stuff just falls off the holes they dirty, make sure you clean them up to stay light ;)

I don't recall seeing these on mine either, maybe I will check again tomorrow morning.

^ You have an '08 so you won't have as many panels as the '09+.

Ahhhh THANK YOU Brociouz!! That explains A LOT!! :D

And thank you to Individual for doing a bit of research for me too! :woot:

Good tip. Maybe I can somehow get the hose under there.

If anyone is interested in buying these underbody panels, I have a set for sale in the Classifieds: https://www.clublexus.com/forums/is2...plete-set.html
