"A little bit" of added NVH won't bother me if I get sharper handling in exchange. My 2021 M3P is plenty refined for me already, I want sharp handling and I can spare some refinement for it.
Race car clunking...if it's like that from the get-go I will take them off. Don't want that. I'm not expecting that though. I consulted with two friends - who I trust in terms of car/driving taste and preferences - about their experiences with spherical bearing top hats on street-driven cars. Neither had any regrets. One is thinking of putting some on his Cayman because it doesn't turn-in as sharply as his more highly modded FR-S (with spherical top hats). Neither has experienced any clunking from their top hats yet, with 10s of thousands of street miles, though they certainly agree not to count on such parts lasting the life of the car.
Everything is a wear item eventually, it's a matter of what service interval I'm willing to put up with. Cheap spherical bearing end links, sitting down low getting lots of water/snow and road grime on them? No, that I can't tolerate, I learned that lesson. But much higher quality (I think) spherical top hats sitting up nice and high and mostly protected from the elements? I'm ready to give them a shot, and I accept however it turns out.
I haven't talked with anyone who has specifically used the Redwood Motorsports top hats on a Tesla. If they clunk right out of the gate I'm taking them right off, but I'm really not expecting that. Redwood themselves said I should expect a little added NVH just from the stiffness, but not clunking if they're working properly.
I'll share my experience on these forums of course. Similarly, if any of you have tried the Redwood spherical top hats, I'd love to hear your experience.
