T-Bar Removal - Any Downsides?

Been a lot of years since I swapped out the stock mounts for aftermarket camber plates, but I do not remember that being a noticeable change in the ride quality. Later, changing the control arm front bushings and caster blocks, and the rear torsion bar carrier mounts and trailing arm bushings from stock rubber to solid/spherical, I felt was a dramatic difference.

You two have a higher comfort threshold than I do. I have two cars with full solid suspension bushings/bearings, mostly RE stuff. They are dedicated track cars. Big improvement on feedback and response on the track. But I found that it noticeably stiffens up the car, and translates more noise and vibration. Feels actually harsh.
For me (personal taste), I would not install all solid mounts and bushings on a strictly street car due to the decrease in ride comfort, and the high cost of the parts (exceptions being camber plates, and the ER spring plate poly bronze bearings). For a dual use street/DE car, then its one of the many trade-offs to consider. For a track/race car, depending on the competition level, it becomes arguably necessary.

I have camber plates on my 951 and a 85.5 N/A and I never noticed any increase in NVH? I tend to think control arm bushings would have more of an impact on NVH on a street car?

I have raised RE camber plates up front on my '88 TS with 425# springs, 968 Castor Blocks, front Powerflex polyurethane bushings and Rennbay Sport ball joint kit all with no increase in NVH. Rear is stock except for 30mm solid TB's. I am planning to install the ER spring plate bushings, along with Powerflex polyurethane inner and TB carrier bushings. I drive my car weekly on the street and this year I drove 20+ track days at Sebring. I have thought about removing the TB's, but have concluded my current TB setup (w/ the additional rear bushing improvements) is the best street/track compromise for the way I use the car. Mike
