Brake, Suspension, and Clearance Questions

[Cramadon02]

Ok. I'm working on upgrading my S13. A while ago, i installed Eibach Sportlines and KYB AGXs. Got a nice drop from it, but i would've liked that gap to be a little less than what it was. I'm currently running stock brake rotors and calipers.

A couple weeks ago, i bought some Q45 Calipers, and they don't clear my teardrops. So i'm definitely going to need some rims that will clear.

Here are my questions.

- Generally speaking, is there a uniform way of knowing which rims will clear the Q45 calipers? (originally i was simply looking at a set of 16 inch meshies)
- Is there another way to remove that slim plating behind the stock brake rotor (to replace with bigger slotted and cross-drilled) without having to remove the entire hub or sawing through the plate?
- Are the Megan Racing coilover conversion kits any good, or am i better off scoring a complete coilover set?
- Does anyone know what kind of clearance i would get with a set of 16s vs 17s with my current suspension set up?

Thanks in advance for you guys' help.
