The part I would like stickied to the first post is the below information, which I believe will help many a searcher.
Stock MR2 wheel size and allowances Stock Wheel size is
"X" inches
Max Wheel size on stock body is
"Y" inches
Stock Wheel width is
"Front/Rear" Max Wheel width is
"Front/Rear" Stock Offset is
"Blah" Max/Min Offset on std body is
"Z" Stock Pattern is 5 x 114.3
As I am looking right now at a set of wheels that are 5x114.3, 8" wide, 17" and +38 offset and I don't know if they will fit.
