I don't think my mech would have aproblemw ith any parets I were to supply him with, but I have no idea as I haven't asked him. Generally if I am going to do itmyself I'll order from fastlane or partsshop, if I am going to have him do it, usually I don't know whats wrong so I let him take care of it.
When I took him my neuspeed springs to put in my car, he did it with no muss, no fuss, and only had good things to say about the outcome. He loved how the car looked lowered with the springs, when he normally hates lowered benzes.
