Bulkheads are refined with improved rear arm clearance with all the high roll center roles without back supply modification. Bulkheads had been completely redesigned to work alongside the long hands and narrower suspension system holders. The bulkheads feature an excellent low anti-roll club mounting position enabling the anti-roll bar cable to be placed directly under the drive shafts to dramatically lower the CG. The bulkheads function 1mm milled grooves for the ball bearing hubs that relocated the bulkheads 1mm closer to the framework center line from each part. Made from premium Swiss 7075 T6 aluminum, black colored anodized.
