Just had the Group N mounts put in today. No more parking lot speed NVH. The Group N put the power down well, but nothing like TorqueSolution mounts that I just took out. Definitely lost some of the racecar feel and sound because the TS models were so direct and stiff with 75 durometer bushings. Lift or press throttle with the TS mounts and you had instant decel/accel feel. The Group N makes the in/out throttle response softer and not as direct or instantaneous. Group N feels about 1/2 as firm and the in/out throttle feel is no where near as good as the TS mounts.
Again, this car is a SC'd commuter and wanted to get better bushings, but went too far with the TorqueSolution mounts. I like how they drive, but the NVH was just a bit much for my daily. I hate rattles, these created a lot of them at takeoff and driving at parking lot speeds.
Next, I'm going after the bushings that mount to the rear of the diff. Bushings are still too soft back there even with the Whiteline insert kit. Saw STI parts for that. Can anyone comment on that end?
I have the MCA traction kit, just haven't got it in yet. No time today.
