I have this noise also. I usually notice it around 35 mph. I figured it was my plastic wheel cover. (Don't judge me.)

 

Plastic wheel covers will make the most unusual noises!! I believe you!!!! I SWEAR that the ones on my Lumina will make an awful noise if they are on certain wheels, so I have to keep them on the same wheels all the time. Everyone thinks I'm crazy, but I SWEAR it's the truth!

 

Don't quote me on this, but I thought there was a TSB out about the plastic wheel covers not fitting perfectly, and moving some during driving. This would cause the tic'ing sound heard on the front.

 

This car does not have wheel covers.

 

Ah, I missed that wonderful two letter "SS." Alloy wheels certainly wouldn't have the same issue.

 

I don't have an SS, but my LS is a five speed. No clicks or strange sounds that I hear, and I'm pretty sensitive to odd sounds vehicles make. I seriousely doubt its caused by the manual transmission, or if it is, that its normal.
