NEED HELP, rims

no you're not, if done correctly...I know a little bit about loads and stress, I'm a mechanical engineer with almost a couple decades of experience with structural analysis and bolted joint analysis. if you use hub centric adapters and higher offset wheels (to give you the proper effective offset) then it really isn't any different than running lower offset wheels....a 25mm thick bolt on adapter and a +50mm offset wheel will load the suspension components the same as the same width wheel with a +25mm offset. my previous car, my hot-rodded 5th avenue, I wanted 17" rims of good quality, but didn't trust aftermarket chinese wheels. it just so happened that the mustang bullit wheels had the look, and strength (OEM quality, cast in the USA) I wanted, but were +30mm offset, and I needed +10mm (5.7" backspace, I needed about 4.95" to fit). Non chinese wheels were going to be $250 ea on up (the centerlines I wanted were about $400 ea), the OEM Ford motorsport bullit wheels were $129 ea. I bought a set of machined, hub centric billet 6061 bolt on adapters, and ran them with no problems for the better part of a decade, and eventually sold the tires and rims when I sold the car to someone who put them on his early 70's charger. the adapters were $190 for the set of 4.



exactly. but the effective offset is the wheel offset minus the adapter thickness. so a 9" wide wheel, +50mm offset with a 25mm thick adapter effectively loads the car the same as a 9" wide wheel with a +25mm offset.....so if the vossens he found had significantly higher offset than he needs, using a bolt on adapter to get the proper effective offset could be a reasonable cost solution, if he can get the wheels for half the cost of new, and throw $200 worth of adapters to get them to work, sounds like a reasonable solution.
