I hate to break it to you, but an object with a flat bottom and a curved upper surface creates lift, not downforce.
So this is partially correct of the Bernoulli Effect (horizontal flow through a fluid increases, the pressure decreases), it is not completely correct. In the case of sticking a flat bottom under a VW Beatle that has a very high low pressure zone over the hood of the vehicle yes. If you look at the under floor of a Lotus Elise or the Toyota/Subaru BRZ thing they both have "flat" under pans or most any Hill climb, Sportscar that races at a high level. Yes all of those have some type of Airfoil that corrects this on the top/lower front of the vehicle with an angle that creates higher pressure above the car than below but if the bottom pan was also creating the same amount of pressure you would effectively "crush" the car. If you look at an Aircraft wing they are all designed with some sort of angle of attack from the Z0 water line in order to generate lift (a long with deployable spoilers or other lift generating surfaces). The cheapest way to see if it is generating lift is to tuft the cab and make some simple Pitot tubes and measure air speed top and bottom. Just my humble opinion though.
You guys are way over thinking it. Just the added weight alone creates more "down force". The shape of it, and lack of high speed needed to actually have any effect on the truck from an airflow perspective makes the long winded explanation pointless.

I wasn't overthinking anything. I was countering his assumption that it was creating a downforce, simply because it was "sticking out a bit".

Pretty sure his comment was in jest. And as the other guy pointed out, the "flat bottom" on his tent doesn't really come into effect as the cab blocks the airflow that would be going under the tent

As was mine. I am the "other guy" and that's not what I said. Lol No matter what, the flat bottom is not the reason an airfoil generates lift.

Short version of the story: Added some downforce today because my RTT has been sitting at the shop for too long.
Long version of the story: I took off my roof top tent (RTT) back in August when I was parting out my 4Runner and left it sitting on a trailer at the shop. Now my friend wants to take the trailer so I have to put it on the Rebel even though it's nowhere near ready for that. Original plan was to paint it black and get the Rebel lifted, and install my bed power box before I put on the tent, but now gotta do those later.
I also need mounting brackets for the tent because I had to micky mouse some bracket together. It felt sturdy enough but I don't trust my own micky mouse work. Hopefully the brackets from BA Tents will work with mine.
And yes, it's sticking out a bit so... downforce!!!

Wonder what the turbulence looks like behind that setup. :giggle:

Busy weekend with installs…

Finished up the Hellwig sway bar with core 4x4 links
Corrected the speedometer calibration with the hyper tech speedometer tool
Installed the GoRhino RB20 steps (kids and wife approved)
S&B cold air intake
Sequential mirror turn signals
And finally some custom caliper covers to add a bit of color behind the wheels

Next up: Bilstein shocks/struts to settle down the Readylift a tad and then some type of exhaust. Go back and forth between Borla Sport and Corsa systems.

Busy weekend with installs…

Finished up the Hellwig sway bar with core 4x4 links
Corrected the speedometer calibration with the hyper tech speedometer tool
Installed the GoRhino RB20 steps (kids and wife approved)
S&B cold air intake
Sequential mirror turn signals
And finally some custom caliper covers to add a bit of color behind the wheels

Next up: Bilstein shocks/struts to settle down the Readylift a tad and then some type of exhaust. Go back and forth between Borla Sport and Corsa systems.
Nice mods! I really like the white caliper covers. Works well.
I’ve noticed a bunch of people using the Core Links with the Hellwig bar. My Hellwig came with some pretty substantial adjustable links. If I remember correctly, the sway bar is available without the links, too. Maybe that’s the reason…
I contemplated the Borla Sport, but went with the Atak.

You installed your Hellwig upside down. :confused:

If they're wife approved maybe I should get a set for my wife for my truck for Christmas. Are the sequential mirror turn signals wife approved also, just asking?

BTW Your truck mods look great.
The steps make a big difference and I like the looks of them…as for the turn signals being approved, I don’t think she’ll ever notice them being different lol

Thanks! I bought my sway bar without the links used from someone else, so I just decided the go with the 4x4 ones since they had a good deal on them for Black Friday.

Are the calipers white covers from somewhere ? I haven’t seen that kind I don’t think. Unless they’re MGP?

i know lol i said "downforce" as a joke. This truck is a brick in the wind and will go higher next week (i hope) lool

not sure yet. I am "grounding" my truck for the time being since I'm waiting for more legit tent mounts to come in. I only use the micky mouse mounts to bring it home lol
i'll see how bad it is once it's correctly set up and try to see if i can test for it lol

What caliper covers are those. They are the first ones I've seen that don't look like cheap caliper covers.

They look like the RC covers, painted white.

The caliper covers are the rough county ones with a little customization. Sanded down the ones from RC and coated them with the VHT high heat primer, white, then clear coat.

They were missing something, so I ordered some of the RAM tail light stickers in gloss black from Reflective Concepts and put them on the another coat of clear. Once the paint cured for a few days, I let them bake in the over at 200 degrees for an hour to truly cure per the instructions. Coating should last a while!
