Hi, guys. I'm looking to get a set of civic si rim for winter tires. They are 17'' * 7, offset is 45. My accord ex-l is running OEM rim, which is 17'' * 7.5, offset is 45. They have the same diameter and offset. Same Bolt pattern 5 * 114.3, same center bore 64.1. The only thing I'm worried about is if there is enough space between the wheel and the brake caliper. If anyone knows, please help! Thank you!

Is yours a 1.5t or 2.0t? If its a 1.5 you should definitely be good (1.5t cars besides the 1.5t Sport have smaller brakes). If your car is a 2.0t, 17s are supposedly hit and miss. I'm not sure how you'd know without trying and seeing if it clears the front brakes.

Also know that with the same offset on a smaller (width) wheel, you're effectively decreasing your track width. The 7 inch wheels will sit further inside the wheel well than the 7.5 inch wheels. In addition to the half inch of wheel width, you're losing another 1/4 inch at the centerline (a 45mm offset in a 7.5 inch wheel is equivalent to a 51mm offset in a 7 inch wheel). You should have plenty of clearance with the suspension in this case, but this is the sort of thing that usually trips people up when it comes to measuring offsets.

Thank you so much for your Information! Mine is 1.5t exl. I'm going to try them out this Sunday. I also got a pair of 3mm spacer, just in case if there is not enough caliper clearance. Will there be any damages by running smaller width wheels?

If you can try them, it should be easy to tell. If they clear the front brakes and you can turn the wheel both directions without getting too close to the suspension, they should be good. You don't need tons of space (even the stock wheels only leave about an inch, at least on my sport with the 19s), but you probably want to leave at least a half inch for camber gain under load.

I'm running 17" Sparco Assetto Gara that came off my 2017 Civic Si. It should be fine.
