i have the nismo bar. didnt get to notice anything cause i only drove it lightly for about 2 hours before the motor went.

but looking at the power brace. all they do is take the stock tc rod brackets, get 2 1/4" thick steel plates, and a 1" bar thats about 2' long. they place the steel plates on the inside of the brackets and weld them in. then weld the bar between the brackets to the plates. then they paint the thing silver and give you a nismo sticker. all in all it should cost you no more than $20 including paint minus the nismo sticker. or you can pay $185+tax and get the real thing or buy the $100 tanabe one.
