I actually screwed up and removed the factory bushings from my '19 Fiat 124 Spider (same as a ND Miata) in preparation for what I thought were offset UCA bushings for more -ve camber. Turns out the offset bushings were for the ball joints instead - duh! - I installed those for the ball joints but then had to find some replacement upper control arm bushings. Not to worry - Nolathane to the rescue - these are so much easier to install than the factory bushings and should provide a bit less flex under hard cornering. They appear identical to various other "manufacturers' " products but the price is much less. Shipping was free and insanely fast direct from Nolathane - just a couple of days. Fit was perfect and easy. My only issue was that the "included grease" per the instructions was not in the sealed packaging. I ended up using a grease packet that came with some previously purchased sway bar bushings. I didn't feel like that was enough to knock of a full star since these are so much better value than any other aftermarket bushings out there. Note that removing the factory bushings is not trivial - I used several methods but highly recommend the Karcepts method.
