J, I disagree with you. Kindly remove yourself from this conversation
With this car, you do feel downforce on the street. The rear end is a bit loose at highway speeds, and can be easily upset on spirited onramp runs. The rear diffuser helped with that a lot. I was not expecting it to be that noticeable, but it was.

Hey, I don't claim to know everything! I'll take your word for it.
Slamming it to where you don't have all that wind making it's way into the wells wouldn't help? I remember it helping a lot on the RSX and TL.
Guess you guys wouldn't know much about that

You shouldn't lower this car more than 1.5". I'm probably a little too low in the front TBH. You get to a point where the roll center is so off that all you get is bump steer, and the car no longer handles the way it should.

It varies from car to car based on the geometry, but it doesn't matter because its not a sports car.

The catback I got has a massive muffler, in the same shape, size, and location as stock. Maybe I don't need it? Or I'm not fast enough on the track to notice the difference
As Morgan mentioned, it makes a difference. But I'm on the fence at the moment.

Anal-yiest
To not kill the the clean look, I say Type 2.
If I was those track guys up there^^^would go with Type 1 though, but I think that plastic thing on the bumper wuld help the air flow passing from Type 2.
Type 1 just passes that plastic bumper thing. Get out of my way.
Jeremy, look at the size of this thing.
Air would rip off my bumper

Birrrrrrr!!!! Pata pata pata pata
I love that gravel machinegun
I don't really know what bump steer is.
Googled but wouldn't alignment get rid of it? Anyways, I am getting lost when it's suspension.
Lowering the TL didn't end up well, so I am staying away from it.
Yes thought of getting TRD lowering springs but my pain being pretty strong in the past made me stop even thinking about it
Ohh I got something to show you guys... wait

To get the most out of the aero, you don't want the air to cling to the bumper. That causes drag, disrupts the air coming off the trunk lid, and reduces down force.
This is going to sound crazy, but you don't want to speed the air up under the car. Fast air = high pressure = lift. Look at those crazy high speed race cars from Auto Union and MB back in the 30s; they were super slippery but preferred to be airplanes.
What you do want is slow air. Slow air = low pressure = downforce. The flip side is that you don't want to slow it down too much, as that would cause the transmission and differential to overheat.
The diffuser basically causes the air coming out from under the car to stay low. You can see it in the CFD analysis. That helps pull the air off the back of the car, which creates the low pressure area just behind the car, which gives you down force. Spoilers do the same thing, but they cause more drag in the process.
I'm still reading up on aerodynamics, so I'm not going to pretend I know everything about it. But its a topic that really caught my interest over the past year and I've been reading up on it anytime I can.

True, I agree with all those magic things.
Even though, I know that fast air means high pressure, I always thought that rear difuser makes the air faster Which would be stupid as you mentioned.
How does that sharp difuser slows down the air to make tires feel more weight at the rear....? I don't know. Magic
Those front splitters would really reduce the air cooling the tranny and diff then...

I believe the reason that the air slows down is not due to the sharpness of the diffuser, but where it is directing the air to go. Since it pushes the air further away from the rear of the car, that takes out of the air pocket right behind the bumper/trunk lid, which causes the air to slow down.
So yea, witchcraft.

FYI - I also have the JDM y0 underpanels to smooth flow out under the car. If I keep the car, I'm getting their front splitter with tie rods.

You had a racecar, but you decided to be a responsible adult instead.
Never go full responsible adult.

It snowed on sunday, today weather was great outside
This shit is getting weird
And just passed 17k miles today.
Dammit
I am positive on nameless, I will do it. Especially now they have new design front pipe I guess, better fit, no rattle or anything.
And waiting to hear more about that new grimspeed intake. Let's see how people will like it or not.

I think it made 7whp over stock on an independent dyno. Not sure if that's tuned or not though.

I have a super top secret way of opening up motors to get the most out of them.
But no, the stock intake is actually pretty damn good. To put it in perspective, a high flow filter and a smooth intake tube (instead of the stock ribbed one) will net 4-7whp. I'm curious to see what the Grimmspeed intake will do tuned.
