I installed an ACT Stage 1 (whatever is rated for just a little more than stock) back in June. 97SE, 139k now. The motor mounts that I could see (front, rear, and drivers' side) were good, but are original. Immediately I had clutch shudder at low speed in fwd and reverse. I attributed it to not resurfacing the flywheel (couldn't figure out how to remove it in a reasonable amount of time), and hoped the disc would break in to it. It got a little better but the shudder persists in low gears at low speeds.
I've heard that going to a stiffer engine mount can fix it, which suggests a resonance issue. As well, during my clutch job I left the motor insufficiently supported for an evening (the tranny side sagged a few inches), and I worry I stressed the pass. side mount enough to damage it.
Suggestions on where to go - mounts, flywheel resurfacing, or something else?
