The plan for these wheels is to have them reworked by Rotiform into something more suited for what you're talking about here. I acquired these from a good friend of mine off of his Z32, which is why the fitment is somewhat askew on my application - they would fit at lot better if my 240 had stock body lines and lacked the over fenders up front...
As for the new wheels that just arrived at my office - stand by for results.
