So I see some doing 18-9.5 + 35 and some doing 18-9.5 + 45. Or 18-9.5 + 40. And I see some tires online being offered in 18-9.5 + 50... and I have no idea why one is better than the other on offset. I assume 18 inch is where’s it at and 9.5 seems a common choice (again not sure why). 5x120 is what I need for compatibility. So like why do one instead of the other on offset again? Is 18” 9.5 still the way to go?

There are few things here. The stock Type R wheels are 20x8.5 with a +60 offset. The +60 offset is required to keep torque steer at a minimum, though it seems that it isn't that bad with lower offsets. The lower the offset, the more aggressive the look (they stick out more if I'm not mistaken). A wider wheel allows you to use wider tires which can technically improve traction. 18" is the smallest wheel that will fit on the Type R as 17" won't clear brakes. Smaller wheels tend to be lighter and lighter wheels mean less unsprung weight which is good for handling characteristics. 18" also means that the sidewall can be taller/thicker leading to better daily driving characteristics.

19" wheels offer a tire that results in 0 speedo error (245/35/19 = 245/30/20 in diameter) which is also something to consider (a 19x8.5 + 60 is the stock for the FK2 CTR). The Motegi MR924 19x8.5 +53 has also become very popular because of these two things (0 speedo error and high offset), they also are pretty light as well. They do offer an additional 1" diameter (½" sidewall thickness) to the stock wheels. I'm not sure if this would be enough for daily driving, though I have no issue with the 20" wheels (except in construction) since the CTR is my DD.

Thanks for the help. I’m fairly settled on 18-inch and a decent offset. I want great performance and will be running Michelin Sport 4 S tires. I also want to avoid rubbing on comfort mode (doesn’t everyone?) which I read could happen if you are not careful on the specs and tire choice. That one poster a while back noted 18x9.5 + 45 was safe and decent for any tire combo so I’m building my knowledge from there. But when I go looking for rims / tires there are some style are just not available in exactly 18x9.5 + 45, some parameters are slightly higher or lower, so I’m feeling out what’s considered a decent combo of specs or spec range. Plus, honestly, can most really tell the difference?

Why worry if most can tell the difference or not. The main thing is if you can.

Personally, after spending the money on the engineering that has gone into the steering and suspension design - who am I to second guess. My definition of performance is more than simply lateral grip. Steering feel and minimizing torque steer under power in turns are just as important if not more so than outright lateral grip. I'd go with a lighter wheel in 18" or 19" keeping the 60mm offset, with a tire that has stiffer sidewall than the OEM Conti but similar width to maintain steering feel. To get more lateral grip, a grippier compound
would help.

Yea I've been waiting to see these wheels with those specs. Look small probably due to the tires, I think they would look better with a beefier tire.
Ive seen the same setup but on a 265/35. Looks good

Well...finally got my new wheels and tires on. Went a different approach after defective wheels were received. Can't say that I'm not pleased with the choice. Love the 18x9.5 +45 Titan 7 wheels. Before mounting them today, I applied some C5 to protect them. Now I have to get my springs (Swift) installed and get rid of the gap! Forgive the dirty car, it was clean till it rained yesterday and today.
