Ideal offset for new wheels

Hey guys, I have a TL-S that I use all year round, and being in Canada, that means in the snow as well. So before getting in the wheels discussion, I need to mention that I have no intention of lowering my car any time soon. And if I did, it would be a mild drop at most.

Now with that out of the way, I was wondering what would be the ideal offset for new summer wheels that I plan to get next spring. I want something that's not too far off from the original wheels but with a bit more of an agressive fitment that will still look good on the stock Type-S suspension.

I'm looking at either 18x8 or 18x8.5. I'm aware the offset needed will depend on the wheel design and whether or not they clear the BBKs, but what I'm looking to find out would be the ideal offset if it would fit the BBKs, no matter what the wheel is.

So if you could get a custom offset, what would be the best for either of these sizes for a mild agressive look? I know I won't get a single answer since the best offset will be different from person to person, but it will give me a good idea of what range to look at.

Thanks in advance!

Or maybe another way to see it would be this: what would be the thickest spacers you could put on the original waffles while staying within the fenders?

You can then calculate what the offset could be for either size of wheels.

For this question, people generally use 15mm spacer up front and 20mm spacer in the rear.

Your first question, depends on what type of "look" you are going for. Which is all personal.
I personally think 18x9.5 +22 is perfect specs, but others may think it's a tad aggressive

Ok that will help.

As for having a 9.5 wheel, isn't that too wide on stock suspension?

Other question that I just though of: how much closer to the strut can you go from the original wheels?

Ok, so I'm still looking around, found more info as to what I could do. I found a wheel I like and I'm debating whether to go for 18x8 +35 or 18x9 +30 if I go for that wheel.

I know the 9" wheels would sit pretty flush with the front fenders and I'd probably put some 245 or 255 tires on them, but with that offset I'm wondering if they would rub the fenders in the back on good dips. Like stated before, I'm on a stock Type-S suspension, but I have about a finger and a half gap from fender to wheel in the rear (sub in the trunk not helping here either) on my stock wheels.

I've seen people here run some 9.5" +40 or +35 wheels (almost same poke) on 255 tires with stock base suspension without rubbing, but would that be the case with my suspension? I do have a slight natural camber rear that could help, a little more than 1 degree on last alignment, but would that be enough?

As long as you can get your wheel lined up exactly with your fender(s) it’ll look awesome.

Yeah, they would. Whether it's 18x9+30, 18x9.5+40 or +35, it's pretty much lined up with the top of the front fender. From what I saw here anyway, checked a lot of photos on the New Wheels/Tire Specs thread. There's a few that posted pictures on stock suspensions with wider wheels.

So you're saying it shouldn't rub?
