Spohn TA Thunking FIXED.
As someone else who had the problem mentioned, the 2 bolts that are horizontal at the back of the TA on theirs was loose, as I just found out mine were. So I clearanced that section and tightened up those bolts and NO THUNKING AT ALL.
I got on it really hard from 0-60 and had no traction at all.
Turbos+ cold weather FOR THE WIN.
Didnt do a 5"X5" section though.... maybe I need to do more. FWIW, all my bolts were hella tight still.
