I can't decide whether I want poly bushings on both ends of the adjustable lca's I'm buying or a poly/spherical combo. I understand the poly/spherical combo will have more road noise than the poly/poly, but will it be too much to take? I'm leaning in the poly/spherical direction because of the reported better performance, however, not if it means being too loud inside the car. Anyone out there running the poly/spherical combo on their car? If so, what are they like?

They can definitely be noisy. You'd better be tolerant of squeaks, rattles and clunks, especially at slow speeds on uneven surfaces. They aren't too noticable on the highway though, or on fairly smooth surfaces.

 

this really should be a decision based on how you drive. If you don't need stiffer rod ends for hard launches and aggressive driving, then go with the poly ends. They are still significantly stiffer than stock bushings. Considering your mod list, it really doesn't look like you have a big problem with traction, so you may only see more NVH from rod ends without gaining the additional benefit.
