I owned an M3 before buying my BRZ, so I'm used to weird moaning/grunting noises from the rear diff and things like that. M3s have this part called a "clutch delay valve." Many M3 owners take it out for faster and smoother shifts. I'm wondering if there is a clutch delay valve that we can remove on the BRZ, because I'm letting the clutch out faster than it is actually "catching" if you know what I mean. It's quite annoying, and I intentionally have to delay letting the clutch out in between shifts for a smoother transition. It's most noticeable shifting into 6th gear.

Also, I'm noticing this weird chirping/quacking noise every time I let off the clutch pedal to engage the next gear. It's most noticeable when I'm in motion on the freeway. There are so many noises this car has compared to my old car that I can't tell if it's good or bad. Please advise!!! Thanks!

In case you're wondering, the car drives fine. I'm just puzzled by the weird noises and clutch timing. Currently has 2,100 miles on it.
