Avid X12 titanium ball studs & pivot balls
Avid have introduced three kits of titanium ball studs and pivot balls for the Xray X12 1/12th scale pan car kit. Machined from billet 6AI-4V titanium the parts are about 40 percent lighter than the standard steel balls without sacrificing strength and they utilise a 2mm Allen head for easy installation and removal. Available is a full 14-piece conversion kit including ten 4.2×6.5mm ball studs and four 5.8mm pivot balls as well as a 10-piece and 2-piece 4.2×6.5mm ball stud kit.
