Anyone have a setup of 15mm spacers in front and 20 rear?

I'd like to add some spacers but can't lower my car because of clearance issues getting into my driveway. It seems that most people are going with 20/25 spacers to get that flush look, which is what i want. Here's my question: I did a measurement using a weighted string on the fender lip and measured from the string to the edge of the tire. Both front and back measured approx. 9/16 in which is approx. 15mm. Big difference between 15 and 25mm. So, i guess you know my question. Are these spacers true to size? Not sure what size to go with at this point.

I didn't know too much about spacers until about a month ago, but I would think that since you're not lowering your Z you should go with 15mm front / 20mm rear spacers because you don't have the added negative camber to account for that you would with at set of springs/coilovers. I would imagine that 20mm/25mm spacers would cause the wheels (especially the rears) to stick out past the fenders, but I'm not certain since I've yet to see pics of a Z with spacers that's not lowered.

G35guy is correct, I was running 15mm front/20mm rear before lowering the car and it was a nice fit.
Now running 20mm front/25mm rear with Eibach springs and -1.8 deg camber all around on a base model with stock 18" wheel and tires. Using bolt on spacers.

Not a fan of extended studs and slip on spacers. Torque can stretch the bolts and create play and loose bolts. Bolt on spacers are safer and much more simple

This thread has confused me a little not sure anymore of what spacer sizes will and won't work because of studs lol I Don't plan on dropping my Z (at least not anytime soon) but would like to add bolt on spacers. I have 13 Touring Sport Package with 19 Rays wheels. Can I run a square 20/20 setup at stock height and be flush all around? or do I have to do 15 up front to keep it flush at stock height?

You will be fine even if you lower some day and want bigger tires.

Ok...now that my head is dizzy and spinning from reading all of this, I think this is the appropriate place to get a final answer since it has to do with correct size spacers.

I'm considering a set of aftermarket wheels that have lower offsets than the 19" RAYS but not low enough, at least in the rear. The fronts should be ok (going on the notion that an additional 15mm - 20mm up front is ideal) at 20x9 et30. That's 17mm less than stock putting me smack dab in between the 15 - 20 window. The rear is what will need a spacer. 20x10.5 et25. That's 11mm less than stock. If I add a 12mm bolt on spacer to the rear that will get me to 23mm which is smack dab in bewteen the 20-25 window for the rears.

This should be good, right?

20x9 et30 on 255/35/20
20x10.5 et13 on 285/30/20

Suspension = ARK GT-F springs (1.20f/1.0r)
