no problem, how would you like it proved?

Depending on the application depends where they are made I guess. And possibly the store.

Pedders website says their springs are made in Victoria, which would lead me to believe Browns springs.

The springs themselves I believe are great quality, the off the shelf stuff is designed with (some) legality and ride comfort in mind.

Hence why they are usually always too soft for what most people want.

As they are just a spring, not a suspension system they are 'matched' to standard shocks which is most cases are shithouse.
