Basically, the reason cars don't come stock with them is the same reason cars don't come with a CAI
. It cost more, makes more noise and the average person doesn't want/need it.
As for the vibration reduction. The only way to do that is to have a set up like the brashboy setup above. But look at the price!!!
For $56 you get all of the performance a little noise and a whole lot less cost. Basically this is the thinking behind the brace. I could make one like theirs but the price would be that high.
As any performance mod you sacrifice a little comfort for some performance.
The gains from the brace are smoother shifting, quicker throttle response, less bogging in corners, less engine mount wear.
The down side is slight vibration at idle, and a low level gear whine. (drowned out by a radio, talking, or wind noise, it's that low level.)
Just a side note on the brashboy setup. notice anything missing on the car--hint--cruise control. You have to remove the cruise to install theirs. My brace is direct bolt-on with no removal of stock components.
Also the front beam of the Celica is very weak and will not hold up to stress of a brace pulling against it constantly.
My brace is rear mount(shock tower) a very strong point on the car. [ 04-29-2003, 05:02 AM: Message edited by: killerm ]
