21.5mm AWR bar
I was finally able to install the 21.5mm AWR bar on my mazdaspeed.
I did this after having the car at the dealership again for clunk work.
My stock racing beat bar has been worn to a smaller diameter where the bushings go. The dealer wrapped the bar to increase the diameter back to stock. They said they could make the clunk go away if they removed the bar.
I said no sh*t!
Anyway, that night I removed the stock bar and installed the AWR.
Install was pretty easy, there were some issues I encountered, but was able to overcome.
It clunks too.
But differently.
I believe it's coming from the endlinks, as they are of a "floating" design and move around.
I used it for the weekend, and am now using the AWR endlinks and the stock racing beat bar.
It seems to make the same amount of noise as when I picked it up from the dealer after they did their thing with the busings.
I'm going to wait a few days and then put the AWR bar back on and compare noises again.
