The stock 356 A and B cars had a 24mm rear bar, and the stock C cars had a 23mm rear bar with the same rating as the A/B bars since they were shorter.

Going up two sizes in the rear bar, in combination with the WR 5-Leaf Front Bars and the WR 17.5mm Front Swaybar Kit, will provide better cornering and a noticeably firmer and more controlled ride.

WR Rear Torsion Bar Sport Bushings are recommended.
