I just purchased a set of wheels and the specs are:

front. 17 x 8.5" et56
rear. 17 x 9.5" et56
bolt pattern. 5 x 120.65
center bore 70.3

I need help figuring out what size spacers and tires to run on my E30. The ET of my stock wheels are 35 on a 195/65/14. I'm leaning towards 40mm spacers to make it sit flush with 205/40/17 in the front and 225/35/17 in the rear on Falken FK452 for some stretch. Any input on this setup?
