Thinking about going from OEM size to a 20" squared setup or a 21" 20" staggered setup. Has anyone who has done this have some insight into how it would impact driving dynamics? Obviously it would be a rougher ride but I'm speaking more towards sporty driving.

I am running 275/30/20 in front and 305/30/20 in rear and rides just fine.

Running 285/30/20 in front and 295/30/20 in the rear and it’s just fine as well.

What exactly are you trying to accomplish? As long as you maintain the tire diameter, it shouldn't affect driving dynamics too much. So stock fronts are 275-35-19, you'd want 275-30-20 or 275-25-21. I don't think you'd be able to go significantly wider on a larger rim because of strut clearance. Apex has fitted 295 19 in the front.

I like the looks of the bigger wheels on this car.
Just wondering what the trade off is.

If you can make it fit in the G87, it's probably not going to completely hose your car. Assuming you aren't going nuts with huge spacers or changing diameters, of course.

But be sure to double check for rubbing on the front liners at maximum lock, it's a common issue.

Sure, the ride will be rougher, you may be more likely to bend rims, all the obvious stuff. And track dynamics will change (under/oversteer, etc.) but doesn't sounds like you care about that much.

There are multiple ways to address the rubbing.

Not sure why you say more likely to bend rims?

There are, yep, I'm just saying to be aware it can happen and check for it.

Fair question. I was making an assumption that anyone wanting to run huge wheels for looks was also going to run less sidewall, and probably also not adjusting suspension to compensate. That's going to increase the chance of dinging a rim on a pothole.
