The chassis mounts TA mount into the tunnel or at the G-brace ( such as Spohn or UMI ). These are much heavier then the sock stamped steel peice so they also act as a stiffner to the chassis as well. They move the leverage back and control the rotation of the rear and provide adjustability to the pinion angle.

The way it was explained to me:

You want to limit/eliminate any flex that could lift a wheel or unbalance the traction between the two wheels. SFC will stiffen up the car, TA will fix and pinion wrap ( upward motion ), LCAs and relocation brackets will aid in keeping the rear square ( Rear moving front to back twisting ).

humm.. so chasi mounts are better? i already have the 3 point SFC's and tubular LCS's and a panhard bar.. guess a good T.A. is on the list next
