New Owner - What are these Mods?

[Jack1.1]

Can anyone help identify these 3 mods? Do you know the Manufacturer and what does it do?

1. What brand of RMM is this?
2. What / Why is this plugged and what does it do?
3. What does this FSWerks do?

Thanks

1. The RMM improves shifting and grip by keeping the transmission from twisting. All aftermarket RMM more or less do the same thing so I'd say leave it unless it's broken.

2. That is the clutch slave cylinder inside the transmission. The yellow cap is for reverse bleeding the brake fluid through it and into the reservoir(Which I highly recommend you grab some brake fluid and one of these and do it! Changing your fluid could possibly prevent slave failure) The other line goes back to the brake fluid reservoir.

3. FSWerks short shift plate. It reduces the shift throw. No negatives there! Only reason you might change it is to go with Mountune Shift plate as it reduces even more than FSWerks, but not worth it unless you feel it's not enough. Even then I'd probably say grab a boomba short shift arm instead.

1. Probably Boomba

Thanks for the info, just trying to troubleshoot my rough idling/vibration which is pretty bad at low speed (1st and reverse) especially with the A/C on it is much worse. No issues once rolling into upper gears (2nd and above) or at more than say 1200 rpm. I think its a motor mount, but not sure.
I was thinking whoever modded the car did something.

The rear mount doesn’t usually add much NVH. Check the other two - one on drivers side below the battery basically. You can’t really see it without removing stuff. The passenger side is right in front of coolant reservoir. The drivers side mount for me is what added the most NVH.

Does it idle at a consistent RPM? What is the RPM?

I switched my rear motor mount; it's the street spec and the A/C shakes the car a good amount at startup. Gets better as the car is driven though.

Check the passenger motor mount as I believe it's fluid filled and most likely to fail.

Much is subjective... Although I don't find it excessive I have had solid mounts in other cars so my perspective is skewed🤷🏼‍♂️ a high durometer RMM will definitely vibrate at with the AC load, a lot of tuners raise the idle to compensate for the increased NVH...

@Jack1.1 have you ever owned a car with poly mounts?
