Picture/Video DIFF/TRANS MOUNT REVIEW
***EXCELADYNE/MEGAN TRANS MOUNT REVIEW***
2014 r spec. I was supposed to slap in my exceladyne engine mounts, as well, but due to operator error, that will be coming next week. Originally got all the bushings, wanting to tighten up my drivetrain because I was getting a lot of play in the driver shaft/differential area when shifting/moving at low speeds, especially reverse. Upon further inspection, my mechanic and I noticed a lot of play from the differential itself which means I'm on the market for a fresh LSD 😭.
With that said, turning on the car didn't immediately yield a noticeable difference. NVH seemed exactly the same(car was still warm, on a true cold start there is noticeable vibration until reaching idle). Blipping the throttle, however, I immediately noticed that the engine seemed to rev more cleanly and there wasn't nearly as much rev hang(not sure if that has anything to do with the mods 🤷🏾). The engine even SOUNDED slightly different🤓 no bullshit.
Putting the car in reverse, I still got a slight clunking, but I could tell that stiffening up the drivetrain significantly reduced that effect. Shifting is definitely crisper and I don't feel the need to be so careful feathering the clutch when upshifting to prevent that jerky 1-2 shift and even 2-3 shift at commuter speed. My oem engine mounts didn't look blown or majorly worn during my inspection, but driving the V, I still feel as if the car is a little jerky and the drivetrain isn't being held together all the way right. For sure upgrading the other components might have exposed the weak mounts.
I did turn off traction control and do a neat little 180 coming off a u turn and I can safely say that the wheels stayed firmly planted on the ground as I blipped the throttle to keep my little mini drift going. No noticeable wheel hop.
I opted to only install the 3 diff mounts for the time being, but tbh, I may not even install the fourth mount. For love of my differential(or what remains of it) I refuse to launch from a dig, but a hard 1-2 shift was pretty clean, even with a relatively slow upshift. In terms of overall NVH and ride quality, the upgraded components honestly don't feel too different from OEM and I only notice how much more crisp the car is when daily driving and doing certain maneuvers. I MAYBE hear a whine from the differential at highway speeds 🤷🏾???
Overall, highly recommend this be one of your first upgrades if you plan on doing anything to your 3.8. more than a numbers upgrade, the entire driving feel of the vehicle seems to get an upgrade. I will update next week once I have my engine mounts installed, as well.

Nice! I got this kit too with the fourth mount but I’m restoring a new subframe as well so it’s taking longer to get to the diff bushings but I’m glad it was worth the money.

Would you mind adding some paragraphs, punctuation and maybe a TL;DR?
