Great thread! I have a 2015 and have a similar build thread and goal.

New Grill and Front Lip

Back when I re-did my front grill to a custom mesh.
Top is cutout OEM GT grill with gloss black diamond mesh and bottom is the OEM grill from the premium model with black diamond mesh behind.
Mesh used was from Customcargrills.com 12in. x 48in. Diamond XXL Grill.

And installed an AFE air scoop behind the grill (connects direct from the grill intake to the air box). That's what that logo is behind the grill on the driver-side.

Installed the performance pack rock guard (mentioned earlier) and front lip around the same time. These pics show off that front lip more.

What that scoop funnels to (does it help? I can't really tell to be honest, but...doesn't hurt and I had the bumper off for other reasons):

GT500 Valve Covers
Also: Ford Performance VCT Solenoids and new spark plugs.

Installed GT500 valve covers and changed the VCT solenoids while I was in there. Hopefully now I can stop sucking up oil through the driver side PCV on hard cornering (luckily getting caught with the driver side catch-can).

Internal differences on driver-side covers:
Not to mention the covers actually have all the bolt holes...still such an odd decision on the stock covers.

Internal (with new VCT solenoids):
I did notice some (what I would consider) odd wear/discoloration on some of the cam lobes. However...I've had the car for pretty much its entire life and never any metal shavings in the oil. I did an oil change after this as well and even cut open the oil filter - not a single sign of any metal shavings anywhere. The cam lobes themselves are super smooth too. So I'm just going to chalk this up to normal wear and nothing's wrong. Anyone who may have any insight otherwise, let me know though.

The rule of thumb I was taught was if your fingernail catches, you have a problem. Dunno if that's still correct on a more advanced engine like the Coyote.

I really wish they [Kumho Ecsta v730] came in 18s. I really love the tire myself.

... they DO come in 18s. I'm considering buying a set of 275/35r18s when I wear out my Firehawks, but haven't learned yet if they last very long.

They do but not in wider sizes unfortunately. The V730s last a bit. Maybe not as long as Conti ECFs but definitely longer than others

Hey! Thank you! Sure -

So it's a configurable module that connects to your brake, throttle and clutch sensors to give you something close to an actual rev-match downshift. Install wasn't too bad but you do have to splice into those wires which are above the pedals. I opted to use "Posi-Tap" connectors to do so(for a more reliable connection) and not use the supplied connectors.

It then works when you are on the brakes and then you clutch-in, you get a throttle blip. If you clutch-in first, then brake - no blip. And you can turn it off if you don't want to use it. I only turn mine on when on track.

Mine's been great so far - never an issue. Does what I want it to do and allows me to get consistent smooth downshifts without using heel-toe.

This is their install instructions if you're interested: https://www.auto-blip.com/pdf/2015+_Mustang_v1_1.pdf
