Q's on wheel offset and SAI February 25, 2009, 10:43:22 PM Steering Axis Inclination. Looking at options for my '87 TC. If I go with the current K-member and 83-85 A arms, my stock wheel centerline should be inboard 3/4" right? So would the stock SAI change if measured through the older style A arms mounting points? So if I go with a wheel that has more backspace and less offset, my wheel should be outboard a bit, but how will that affect my scrub radius and SAI? Has anyone figured it out? Plus, what is the stock offset and backspace? My car came with 4 different wheels.My thought is running an older style steel wheel from the early 70's. However looking at everyone's Cobra R's and the offset they have, I have to think the stock suspension will "tram line" if I go with an older wheel (less offset). Shortening the suspension width by switching up the A arms seems like the only feasible way. Unless I can find an old style wheel with the same as stock offset. Have I confused everyone yet? no? Maybe I'll try harder next time, lol. Quote Selected
