I just purchased a Mazdaspeed rear sway bar for my 07 speed 3 on ebay and here's the problem I'm having. The stock bushing mount are way too small for the urethane bushing(that thing is huge) and the bolt on the end link are too big for the sway bar. I tried to call the dealer for help, but no luck. I compared to the two side by side and I really don't see much difference in size, but the Mazdaspeed(the one I just purchased) is a bit heavier compare to stock. Just wonder if anyone here have the same issue as I do?
