Need help with starion wheels on s14

[732sr20det]

I picked up a set of starion rims fronts are 16x7 +18 and the rears are 16x8-10.. the backs line up good the fronts hit the caliper bracket can anyone tell me the size spacer i need should i just use a slide on or a bolt on? also i have q45 brakes all around!

I'm not sure with Q45 brakes, but with stock S13 hardware, you could either run 3-5mm worth of spacer, or grind the caliper down until it no longer rubs.
