I'm upgrading my rear cv axles by adding the short axle off a Pathfinder. This requires a .5' thick spacer between the cv joint and the stub axle.
What is the preferred material to use: mild steel or aluminum? If it's aluminum, how 'bout some help regarding the choice of alloy. I've searched the web for aluminum "drops". There are several different alloys... some quite pricey. 6061, 6063, 7075, and 2024 seem to be the most common. Additionally, some are tempered as T6, which I understand increases the strength of the alloy.
My real question is which of these alloys is preferred for wheel spacers?
Finally, is there any reason not to buy a 6 inch round drop and machine it to .5 thick rather than a .5" plate drop and turn it to fit.
