Has anyone used the Turner monoball front control arm bushings on an E36? If so, do they improve steering feel, how is the reliability, and how bad is the increase in NVH? My car is primarily a street driven car, and I am trying to decide if the benefits of this product outweigh the cons.
In specific, here are the parts I am referring to. I have no affiliation with ECS tuning.

These are similar to the old "treehouse racing" lolipops that used to be available. From people I've talked to and accounts I've read when researching, they will absolutely be a step above stiff poly in terms of NVH. These are a metal bearing surrounded by delrin. There's not really any give/deflection as there is in rubber or even poly. Everything is going to be transmitted from the control arm straight into the chassis.
Personally, I briefly considered these or something similar for my upcoming suspension bushing refresh but decided to just go with 95A poly instead. Unless someone else has a different experience, I'd suggest caution if you're considering these for a car you regularly drive on the street. If it's a track toy by all means go at it, because racecar.

I have been using the slr eyeballs on the street for the past year. The are bearing bushings that don’t even articulate. Have also run Delrin and poly. You will hear a light bang occasionally on rough roads or over railroad tracks as the sudden change in surface is transmitted rather than absorbed. Poly is much more forgiving. But I have not tried the articulating bearing bushing — it’s ability to move should help.
You get a TON more feedback and road feel with them vs stock bushings but I wouldn't consider it an overbearing NVH increase for daily driving use. Now devils advocate my personal daily driver I'm not running them, I'm running boring old stock bushings (well new as I just replaced them), I went that path as comfort is my core concern with the daily driver/family hauler, not feedback and the like. On my toy/track/etc car I'll be running them once I overhaul the suspension in a few week, going from poly to these monoballs to maximise feedback.
