In the rear of his car, to make the whole thing vibrate less, and become more stiff, etc., How would he go about doing it??
He said he wants to try to find the upper part of his frame on both sides in the rear of his car, below the window and attempt to bolt a bar across it, almost the same way that a strut bar would install, only ON the frame, not in the strut towers. Would that work at all??
