So after removing the Spyder, and re-installing the factory noodle (with a new crush collar and pinion seal), the vibe is still evident at 90.
Not bad...you have to have the windows up, radio off/muted, and be on a reasonably smooth road, but it's still there, albeit dampened by the noodle's rear section. I guess the poly bushings from the BRM rear sway bar and CHE UCA and panhard bar do transmit more NVH to the body than the stock bushings, because I really don't recall feeling the vibe prior to their installation.
Since the stealership's techs won't drive it above the speed limit, their installing the vibration analyzer and then calling me to drive it while one of them operates the machine....going in Monday to have this done. Hopefully the vibe originates in the pumpkin area so they'll open it, measure the round-out on the carrier, etc etc.
Just venting.....the car is a source of pleasure as I love how it looks and how it hauls with the 91Tq tune and 4.10's, but the vibe frustrates me...I feel it's unacceptable to have the vibes...am I being unreasonable to expect vibe-free operation up to ~140 mph?
