The new wheels I bought (Rota Kensei) are wider in the rear than the ones I have from Vic's - 9" vs 8", both zero offset. I needed 1.5" spacers for the 8" wheels. Before I order new spacers for the wider wheels, to make sure the overall track is the same, I wanted to get others opinions on my math - which sucks in general. I am assuming that I need to move the new wheel in by .5" (since they are zero offset) to achieve the same track as I have currently. So, I would need to order 1" spacers to replace the 1.5" I'm using now. Does that sound like a reasonable calculation?
