Stabilizer/rollbar /sway bar depending where you live. Does anyone know the dimensions of the front and rear bars like Scuderia Topolino used to sell? I am after the diameter and whether they are hollow or not. Or any suggestions. Currently I have a wishbone front with Bilstein coil overs and no sway bar. Rear is gas shocks and Abarth 1300 coils and the stock sway bar.
