Replaced coil springs myself. The OEM coil springs are very thin and not durable as this should never happen to both of them. It seems this isn't an isolated problem as other Mazda Owners had to replace their Coil Springs also. Easy part is to remove the springs but the hard part is replacing the Swaybar links as they are rusted on and you will need to cut them off. Tried first with Skillsaw but metal is really hard and just dulls the blade. Best to cut off with a torch otherwise you will spend an hour or two just to cut off the Swaybar Links with a Hacksaw along with using a file for easier extraction. Bought Generic Swaybar links with modification so you can hold the bolt with wrench while you are tighten it up with a second wrench. Stay away from OEM part as they use a useless Allen key to do this part.
