Current setup:

Stock suspension with tein springs
Cusco floor bars
Cusco front tower bar
Cusco lower rear bar
Cusco U lower front brace
RE01R tires
Alignment in stock spec

Cusco U lower front brace and rear lower bar was added first and everything else later. When I added the tower bar and new tires I noticed my car tramlining more especially on rain grooved freeways and crowned roads. I immediately thought it was the tires but I had similar tramlining experience when I had a MUZ front brace with different tires awhile back so took it off. Tramlining and twitchiness went away. Possible for front brace to have caused the tramlining or is it the tires combined with the front brace that increased tramlining effects?

 

Tramlining is not a word. Yes, I looked it up on websters.com

So you might want to try to explain what you mean as that word is not doing it for me.

Ok, I found something on tirerack.com

Tramlining may not be a real word, but I know what he means, we get it with the Insight. A change in alignment has helped many Insight owners, but it will decrease milage.

 

I'm guessing tramlining is when your car seems to follow the grooves in the road?

 

It is definetly associated with tram (streetcar) tracks ... but not the tram driver. The term comes from the vehicle driving along the tram tracks in the road that experiences the "wiggle" from the car trying to negotiate the tracks ... especially if the distance (width) between the wheels is close to the width between the tracks ...
