I am looking to order some 18x8 front and 18x10 wheels for my 72. They will be used in conjunction with wilwood 6 piston/14” rotor front and 4 piston/14” rotor rear, which aren’t installed yet. Weld’s application guide is suggesting a backspacing of 4.2” front and 6.2” rear. From reading in the forums, it seems like 4.75 front and 5.75 rear seems to be what guys are running. A guy I follow says his were 4.65 front and 6.1 rear. Due to the build time of 6-8 weeks, I’d like to order now, and get the brakes installed during that time. Should I go with Weld’s recommendation? Will the brake hat thickness change the offset required?
