New rim rubs the caliper

DO NOT USE 1/4 SPACERS!!!!! I have been down this road, you have hubcentric wheels, you need hubcentric spacers!!!! I can tell you with 100% confidence cheapo spacers do not work, they vibrate like crazy.

 

im leaning more towards grinding

 

^ It's actually not as difficult as you think. I had to grind the calipers on my old car (IS300) to get a particular wheel to fit. I only had to grind the front calipers by about 2mm which is negligible as far as safety.

All you need is an axel grinder and some caliper paint to cover the exposed metal when you're done. Each wheel takes about 30 minutes.

 

4.5 BS only equals -12 offset on an 9" wide wheel. For an 8" wide wheel, as the OP has, 4.5 BS is zero offset.

 

Im still debating on what I'm gnna do Im driving to new Mexico from california so what ever I do is gnna have I wait till I get back
