I just installed these two… Does the vibration go down after driving for a while? That’s unbearable! My legs, my butt, my pedal, my shifter, and my mirrors are all vibrating a lot more. There is so much vibration everywhere. Did install it wrong? Is the majority of the vibration coming from the...

Part number: JR3C-7J323-AA I’m installing the steeda transmission support. This part wasn’t in their video so I’m curious as to why I have it. I can’t install the rubber piece, nor can I fully remove the bracket without removing this part… but the O2 sensors are in the way… and they’re on their...

Any coupon codes available? Would love to use one right now! Thank you!

Is it my stock clutch? Is it my transmission? It’s getting warmer here in WA. Today was 76°f. The car absolutely hated shifting. Anything over 5k rpm locked me out of 3rd gear. 2nd and 3rd gear felt like they were on the verge of blowing up. Doing a pull from 2nd and it locks me out of 3rd and...

Are there any discount codes I can use? I’m looking to purchase an On3 kit

I’ve done some basic performance mods. I have LTH, Exhaust, CAI, and a tune. But I’m bored of it. I’m making about 450rwhp and I’m used to it now. The car is really loud with the valves open and that’s been the only thing that makes it fun to drive at the moment. I already have suspension...

My driver door handle stopped working. The sensor unlock works, the interior door handle works, but I can’t open the door from the outside. The passenger side works perfectly fine. Last night I got in my car to go get food, after coming back to the car it just stopped working. I hate working...

I have a 2018 GT. I have an OEM clutch. Why does it feel like my clutch is still engaged, or super delayed when shifting at higher RPM? Shifting around 6k-7k rpm feels brutal. Even if the clutch is warmed up. It’s as if I’m no lift shifting, even though I’m always lifting. The car jerks too...

For the past year (almost 2) I’ve driven on 28-29psi. During the summer it was at 31psi. Right now during the rainy and cold season in WA, I have it set at 27psi (warning light comes on at 25psi.) I have it set that low so I can get more grip, especially in the rain. I feel like the car would...

Just curious if anyone has swapped another motor into their S550? Whether it’s putting a 5.2 into a 5.0 or something else into their S550. If so, how is it driving a mustang with a different motor?

I have a tune on my car. I also have a ghost cam tune i rarely flash on, just for fun. I flashed the ghost cam tune and heard this noise coming from the engine. A clicking/ticking noise (not referring to bbq tick) On the Normal tune, my engine is quiet, on ghost tune, it makes this noise? Can...

I’m always reading about how many of you are installing upgrades and boosting or own multiple mustangs. What do y’all do for a living? I have a 2018 GT but buying an $8k supercharger is a lot of money for me! How do y’all afford all these fun upgrades?

After the dealer installed a new clutch on my car and put back the transmission and shifter, this little annoying plastic piece (reverse lock) now vibrates and rattles. It is by far the most annoying sound my car makes. How can I fix the rattle? It happens both when idling and driving.

I’m trying to wire up my eBay RTR lights (I know I can get the real ones, but I like the fake ones with the white color) You have to wire these to your fog light connections. Do the fog light connectors exist? The ones that are molded onto the fog light? I’m planning to buy these and my goal...

I have a GT500 diffuser on my ‘18 GT. I also have a OEM ‘18 GT350 exhaust. The GT350 muffler tips bend more to the outside, which makes them push against the 5inch tips that are attached to the diffuser, kind of free floating, attached by screws. With the valves closed, you can hear the two...

First time really noticing it. ‘18 GT, MT82. Shifter vibrating like this at idle (cold start in the morning) Is this normal, or is it time to change out a part?

I need to remove hard water spots from all my glass. I have no knowledge of what I need to buy. I have a battery operated Milwaukee grinder that supposedly I can use as a polisher, with the correct attachments. Which attachments/chemicals/soap do I need to be able to remove all these water spots?

I’d like to buy a white set on wheels for my car. Post your photos for ideas! Looking to still keep the 19” size These are my current black wheels but maybe it’s time for a change?

My car came with eBay (I think) RTR style lights. The previous owner did not have them connected so idk which wiring harness I would need. My plan is to wire them power to DLR pin and ground to ground pin in the headlights wiring. - Red wire is apparently ground and Black is Power on the RTR...
