Jeff - actually I suspect your Trigos are the wheels with the odd backspacing. I have Trigos, Magnesium Kidney Beans and have also had identical Mag FIA's on my car (from the same supplier at CSX2009). The Trigo's have a much bigger backspace (even proportionately given the +1" width in the front and the back of the Trigo's vs. the original style FIA wheels). Clearance becomes a big issue with Comp Girling Brakes which I believe dictated the backspacing on the original FIA wheels. I have to check my notes on original FIA backspacing, but I suspect that these wheels are to 60's FIA wheels specs. They got creative in the machining of the Trigo wheels to allow the bigger backspace to still fit over Comp Girling brakes although it is REALLY tight. I highly doubt you would be able to run those huge Billboards on these FIA wheels and not have them hang way outside your flare. Put some 215/70 front and 245/60 avons on the front and rear with these wheels and I bet they would sit perfect on your car.
