PLEASE DO NOT PM ME ASKING WHAT WILL FIT. I ONLY KNOW THE INFO ON WHAT IS POSTED BELOW.
RSX Wheel Offsets and Tire Sizes.
All sizes and offsets listed below are known to work and have been used by a member here. Another tire size or offset may work than those listed, if you have used or are using an offset and tire size that is not listed below, post a reply to the thread and I will try to add it. Please be sure you
know the offset works before posting
and pictures always help too.
Shown below is a list of wheel sizes, offsets, and tire sizes known to work with them. All of the information below is based on RSXs without widebody kits and unrolled fenders.
This way everyone will have an idea of what works on a stock body, lowered RSX. Also, these sizes are
without the use of wheel spacers.
I hope this helps everyone...

-Offsets, Hub-Centric Rings, and Counterbores-
Basically offset is the distance from the centre of the wheel to the part of the wheel that sits against the hub of the car (mounting pad), more commonly measured in millimetres (mm).
As you can see in the diagram above, a positive offset is when the mounting pad of the wheel is toward the outer edges of the car and a negative offset is when the mounting pad is towards the centre of the car more. An offset of zero is the absolute centre of the wheel and would have an equal distance to each side of the mounting pad. For the RSX all of the offsets should be positive (+) I don't see where you would want or need to use a negative offset at all. The offset will change on wheel width too, you won't have the same offset on a 9" and a 7" wide wheel and have them fit the same on the same car.
When you buy aftermarket wheels the centre bore of the new wheel will be much larger than that of the stock wheel, this is because of the wide range of hub sizes on different cars and not all cars are made the same. So what the wheel manufacturer will do is make the hub size the largest so it will fit over any hub and then a hub-centric ring must be used to make up the difference between the RSX's stock hub size and the aftermarket rim center bore size. These are usually made of plastic or aluminium and should come with your new wheels to prevent any vibration that may occur. Without them, your wheel will not be truly centred on the hub and at certain speeds, your steering wheel may shutter and/or vibrate, just like an unbalanced tire - not a good feeling.
