This Is our first piece made for Scion owners. It is constructed out of 3/4" tubular 1040 steel with a 1/8th inch wall thickness. This brace fits the second generation Tc2 and has provided an amazing benefit to handling and chassis rigidity. This piece is successful due to the fact that it ties the tops of the shock towers together to make a unified rear end. Cargo space is still available to allow those who daily drive to feel the confidence of a track car and still get the groceries! We are the only company out on the market making pieces like this and for the price and performance the TB advantage can't be beaten!
