Need advise on a torque wrench purchase. I am going with CDI. I cannot make up my mind on wether to purchase a 3/8 or 1/2 inch drive. The range I need is 20-150 ft/lbs. I know that most are going to tell me that I can just get a 3/8 inch drive and use a 1/2 inch socket adapter if needed but some will say that the torque accuracy then also changes. I am mostly using the torque wrench for Brakes, Motor mounts, shocks, struts, and suspension parts that include lower and upper A arms ( double wishbone), control arms etc. Please advise
