The lack of compliance in a metal bushing will cause your car to bump and jump on the track, especially when that track surface is not exactly perfectly smooth as are most smaller tracks or older tracks. The poly is the last place of flexible compliance in your suspension. Besides, you KNOW damn well you ain't only gong to track it. It will be street driven too

He's asking about solid mounts not bushings.
Don't know about drag racing but on a road racing car they are used to keep sudden lateral weight transfers to a minimum.
Obviously not meant for a street car.
Metal bushings are great for suspension articulation and feedback.
They do required periodic maintenance and are wear items.
They don't make your car "bump and jump".
That's probably poor suspension geometry/setup coupled with cheap coilovers.
I daily drove on spherical bushings for a couple of years on my last s14 and it drove well.
The Skullworks s13.5 that place 2nd at last year's Import Tuner FR Shootout:
solid mounts - check
spherical bushings - check
garbage coilovers? - hmmm, no
