Default Wheel spacer help with 245/45/18

I'm going to replacing my tires with 245/45/18 as that's the nearest size my favorite tires come in. At the same time, I'd like to address the looks. I've never used spacer so I'm a noob in this regard. I'll obviously be using high quality bolt on spacers. My questions:

1) What size spacers front and rear will work with my tire size?

2) What brand of spacer is available in the size I need?

Thanks!

You'll want 30mm rear, 20mm front, hubcentric
Ichiba version 2. Version 2 spacers

What are the specs on the wheels you are using including their offset? The tire wheel and the rest of the suspension work as a system.

This has been gone over a million times. Search!

RRocket,
Looks like Ichiba uses both regular and mobile applications for their website.
If you clicked the spacer link in post #2 from a mobile device then it does look like they don't offer the 30mm rear size.
If you click from a pc, you'll see all the sizes though the 30mm shows out of stock at this time which is why I provided a link on Ebay.

The search function is always hit or miss for me here. Sometimes I find what I need...other times not so much.

Just curious - how did you come up with this answer?

He's looking to change the position of his tire/wheel in relation to the fender well so they don't appear swallowed by the wheel wells.
After exhaustive research and many trials and opinions from those adding spacers to our SC's, this is by far the most desirable combo for those wanting to accomplish this. Not for everyone but each to their own.
and.....it's what I have on my own car

Default Double check with this offset calculator

Here is an actual calculator that takes most of the significant fitment parameters into account. Even though it has been posted many times you are right it is hard to find.

https://www.wheel-size.com/calc/?whe....1875in&sr=0in

I inputted the stock size in the first column for your convenience. You can vary the parameters in the second column.

BTW I used 10mm spacers with 18x8x 50mm offset wheels with stock size tires. This give me a 40mm offset, giving me a slightly widened track that works well with my upgraded rear ISF sway bar - for me.

Oh, it does look better too.

Good info Ivan,
My thoughts on spacers 20 and 30mm are stock wheels with stock offsets

Does a 30mm on the front stick out past the fenders? or you just prefer the look of the 20/30 combo?

I've seen a few people say that combo works well, just curious what the reason is that people didn't do the same size on front and rear.

I used a 25" Front and it is perfect:
