BlueScooby's 06 STI - Maddad Whisper INSTALLED! (with pics)

Hmm, I'm kind of interested in this "utility panel". I may have to steal the idea but as a panel where the rear seat bottom would be. Get a flat base and storage.

Not that I'm not still interested in the flat bottom panels project too (that's where you're trying to make the bottom of the car nice and flat, right?).

Re: BlueScooby's 06 STI - Maddad Whisper INSTALLED! (with pics)

"Utility Panel" might be a bit of a flattering name... Its basically a wooden version of the plastic barrier between trunk/backseat that I can attach some tools to that would otherwise be sitting in the spare tire... It was getting a bit crowded in there, and this allows me to free up that space a bit. I'm one of those guys who likes to travel with some basic tools in case I need to work on/fix something while away from home. I'll post up some pics once I wrap it up.

Right now I'm planning on attaching some hand tools and a small air pump.

Yeah, the flat bottom panels are to make the whole bottom of the car flat/smooth. The front portion of the car is already done, my next step is to make panels to extend from the OEM panels (under the main cabin) to the exhaust midpipe. After that, the next step is a combination of panels under the gas tank area, and mating to a better rear diffuser.

I was considering buying the JDM transmission splash guard, but it would cost like $140ish shipped (IIRC) and its not flat... So no dice on that.

I'm thinking of going with the Mature diffuser (in FRP of course, CF is a waste of money IMO)


All in all, I'm hoping to net a slight reduction in lift (commonly misrepresented as "adding downforce") as well as drag. I doubt that I'll do any scientific testing to verify the results, but it sure would be neat to see an mpg or two average rise to prove drag reduction. I believe the principles are valid, so even if the end result is negligible, its still something I made that is unique and SHOULD be functional. :)

Re: BlueScooby's 06 STI - Trunk Utility Panel (with pics)

So here is the "utility" panel I made. Its basically a tools holder. The spare tire is already full with jumper cables, oil, and lug wrenches/keys, so I needed somewhere else to keep these.

Items I have attached:
Air Pump (powered by cigarette lighter)
Small Socket Set
Phillips Head Screwdriver
Flat-blade Screwdriver
10mm Extended Socket
12mm Extended Socket

So far it appears, most small repairs should be possible with this small set of tools. These are all duplicate/cheap tools bought specifically to be in the car.

First I removed the rear seat to mock it up with cardboard:


Here is about halfway through attaching the different tools:


The final product awaiting installation:


It's installed!


I used the two bolt holes on the rear seat support bars as the mounting point for the panel.

I also have some more room to expand with a few other tools, should I feel the need. :tup:

The fit isn't perfect, but its close enough. Over all I'm very pleased with how this came out. My inner nerd/engineer/needallthetools is very happy :)

On to the next project!

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

So, I mocked up and cutout the panels for the under-cabin section of the car. I cut the plastic a little big so I can make the final trimming accurately with these on the car. Going to try for getting within 1-2" of the exhaust. I will have to check back after installing to see if there is any heat warping going on.

Here is the cardboard mockups:


And the ABS Panels cut out.


Once I figure out how I wills secure these, I'll get some pics on the car.

Also, not that this really matters much, but the ABS panels I've been buying come with a textured side and a smooth side. I've been placing the textured side face DOWN, with the assumption that the "golf ball principle" will help to reduce drag on the textured side more than the smooth side.

"Phase 3" will be the panels under the trunk area.

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

(phase 2) Flat-bottom panels update:

So I finished one of the panels and installed it this weekend. I think I got a little aggressive with trimming out the silhouette of the exhaust on this one because I thought it would be hanging higher, but its not bad. I will probably not trim off as much on the other side.

Before I get into pictures of work, I wanted to layout my plan for the aerodynamic panels.


Phase 1:
Item #1 in picture: Beatrush under tray and flat bottom bumper panel

Phase 2:
Items #2-5 in picture: ABS panels under cabin area
(EDIT: ABS Panels have been replaced with Aluminum. Panel 2 & 3 are now one panel, and Panel 4 & 5 are one panel.)

Phase 3:
Items #6, 7 in picture: ABS Panels under trunk area

Phase 4:
Item #8 in picture: Upgraded rear diffuser


With that being said here is my work on fabricating and installing panel number #5:

Mocking up to cut for tab connectors:


said tab connectors:


testing fitment (fits pretty snug :tup: ):


finished trimming out exhaust silhouette (ignore how large the hole is on the front end, I had struggled to line that one up...):


and the final installed product (notice the "plate" I had to use for the enlarged front mounting hole...):


Now to move on to the other side (panel #3)!

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

panel #3 and #4 compete and installed!

(never mind the duct tape, thats so I can clean some stuff up with JB Weld. The tape will come off)

Working on panel #3:


Close up of #3:


Close up of #4


#3 and #4 installed!


Next up is panel #2, or that gaping hole under the transmission in between the panels...

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

So since its warming up I got to hit the local Cars and Coffee for the first time with my boy. He loved it!

There were a couple Ferraris, Lambos, Mclarens, Supras, GTRs, etc. There was a great showing!

Here's a quick pick of me and my slightly distracted son... haha

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

Pah! Attending car shows when you could be continuing the flat bottom project?! How dare you?!
Haha, I know right!

(Side thought; is the flat bottom project what most models are doing?)
:rofl: THATS HILARIOUS! I'm totally stealing that.. haha

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

One more thing. I realized I didn't really discuss how I was mounting the panels so far... I showed the "tabs" I used for mounting the panels to the OEM panels, but the other side of the panels is attached via bolts. It turns out there were some existing threaded holes free that I could use! I need to investigate the trunk area for mounting locations still though... Could be difficult.

Here is what I've used so far:

Sorry bro, it's trademarked now. ;) just kidding, feel free.

I'd think maybe some sort of drop connections might work, like tubes with welded in nuts on the end (or bent aluminum bars like I've seen a few diffusers use). Those might work for the center of those rear panels, and then run the sheets farther up to solid points.

Thats a good idea. I've been looking for simple/existing mounting points so far that didnt require a lot of work to use, but I may have to do something like that... We'll see how creative I get :)

Glad to provide input. I'd say the "S" shaped (more like a "Z" with 90* angles) would be the easiest and easiest to replace. Seems like it's good enough for the diffusers out there at least. I'll keep watching for the progress anyways.

Re: BlueScooby's 06 STI - Flat-Bottom Panels (Phase 2)

In light of the upcoming track day on friday, I pushed myself to build the last panel for the "phase 2" portion of this project last night.

Its not quite as pretty since I had to use two peices to fab the remaining panel. Got a little creative with the supports, but the end result looks pretty good (from under the car anyway).

Here is the "#2" panel being fabbed:


Here is a closeup:


And here it is installed:


Overall, I'm pretty pleased with how this turned out. I wish there were less screw heads on the bottom side, but that's small peanuts really...

I'm driving down to Columbia this afternoon, it would be fantastic if I saw ANY jump in MPG on the highway...

Next up is to buy more panels and move on to Phase 3.

Re: BlueScooby's 06 STI - Flat-Bottom Panels - Phase 2 Completed! (with pics)

Great project. What are you using to cut the ABS with and how thick are the sheets?

Thanks! The ABS panels are about 1/8" thick; they have some decent rigidity to them. As far as cutting goes, I'm just using a basic rotary cutting tool (giant dremel basically). Looks kinda like this:


EDIT: Not that it matters much, but you don't really "cut" this stuff. You're actually melting the plastic. The melted plastic flies off in tiny pieces similar to saw dust though, so it seems like cutting...

Re: BlueScooby's 06 STI - First Track Day! (with pics!)

Had my first track day at Carolina Motorsports Park on Friday! My boss and I were both going to be in Columbia on Thursday, so we made last minute plans to attend their "Turn One" open track day event. It was a blast! I knew (in my head at least) a lot of the fundamentals from reading a bunch of Ross Bentley's "speed secrets" books, but applying that is a different ball game. The instructor I had was great and really helped me on taking the best line/pedal work/smoothness/shifting. I could tell I was definitely getting faster, but unfortunately I wasn't timing my laps, so I have no real record of how well I was doing. On the 4th session I ended up passing a Porsche Boxter (who was in the classroom session with me) and he was supposedly running at about a 2-min/lap pace. So I should be around there as well.

My boss came out in his C63 AMG. I know it has KW coilovers and a full exhaust, but I'm not sure what else. Turns out I was faster than him :cool: Probably due to AWD and having more aero tho...

Heres some pics.

First thing in the morning, ready for 2 parade laps since "new" track to me...


My spot. Track is on the left.


Me and the bossman's car:


Boss going out for first session:


Rock hit the A/C Condensor in the 4th session and sprung a leak :(


Notice the big rock sitting right below the refrigerant squirting out...


Packing up to go home:


One track day and I'm in the "brownbo" club...


Cleaning the wheels today and see this:

Both caliper bleeders on the front right had the plastic dust caps removed. This is directly above the outer bleeder. Makes me think that the heat/pressure forced some fluid to squirt out?? Anyone else seen this before?

Tore my MPSS to shreds with only ~5,000 miles on them...
