Since then I can get some nasty bucking if trying to launch hard. It gets worse when after spirited driving for a good session. It’s tamed a bit since installation, but still occasionally it gets obnoxious. I was thinking it was break in norms, but it it has not stopped yet.



Also, I did have a Whiteline trans mount bushing installed. And lately, an HKS supercharger which has shown me how soft the bushing package really is making the issue more prevalent.



Now, to the solution space. I’m not sure if this is the engine/trans mount set or the rear end suspension bits. Any comments appreciated as to where to start. Which might just be buying a GoPro to see the problem.



My car is stock suspension wise other than the Whiteline trans bushing. I’d prefer an STI parts solution, but not sure if they address the rear end bushings with different parts like the STI grade engine and trans mounts.

It's the Whiteline trans mount 100% I had the stage 2 sb clutch in prior to doing the mount and Perrin insert. Take offs are still smooth but I do get some low speed bucking in 1st gear. Never had that before. So guessing that's what your feeling. Clutch feels OEM and take off is the same for me
