I replaced the OEM front strut brace on my 2009 Vibe GT with a TRD front strut brace today. The installation was alot easier than I thought it would be. It's tedious because of all the parts and bolts that have to be removed, but it's definitely not a hard installation. I didn't encounter any issues and the entire installation went really smoothly and only took about an hour from start to finish, including doing some cleaning under the cowl pieces before re-installing them. I also decided to removed the TRD badge as I'm not a fan of badges, logos, etc.
The TRD front strut brace not only looks much better than the goofy looking OEM one, but it weighs about half as much and since it's one piece as opposed to the three piece OEM one, it should provide much more ridgidity and thus better handling.
