I have a ladderbarred minitubbed mustang with a 315 D/R on a 12 inch wheel. I have Strange DBl adjustables.Car leaves great but past 330 it starts to wobble back and forth.I had 14.5 lbs in it, is that too low? Any input or is that common for the Drag Radials? I have never ran them before.If this is in the wrong forum, feel free to put it where it belongs.Thanks.
