Superpro are made in Australia. I first found out about them from Flyin' Miata, a well-known and respected Miata tuner.

I've made 3 posts about them in recent months, perhaps you didn't do a search. I spoke to them over the phone and they drove home the point that they actually test drive their bushings. And they don't just go with the hardest material for all their bushings. They select the hardness as a reasonable compromise between desired reduction of flex, and NVH (noise vibration harshness). Their TA bushings are soft enough to allow the necessary articulation as the factory engineers intended. I bought some ES TA bushings and their rock-hardness kept me from installing them and started my search for softer aftermarket bushings, which ended in my installing the Superpros.

I just installed the front hexagonal bushings a few hours ago, and I'm quite pleased with them. I tested them on a mountain road.

Here are the US distributors:
