swingarm, 530-630, spacers?????

I plan on buying a 6in extended swingarm with a ninja rim on it. I understand by reading the posts on this site, that I will need a 530 front sprocket and chain to match up to the 530 rear sprocket. I have found a chain, and a front sprocket on www.z1enterprises.com . But if the ninja rim is much wider, will the rear sprocket line up with the front sprocket? Does anyone have any other unexpected troubles I may encounter when doing this swingarm swap, HELP WOULD BE GREATLY APPRECIATED!!!!

here is how I'm going to go about it. First you need to get the swingarm and wheel on. Snap a chalk line and roll the bike on it keeping the front wheel centered on the line. See where the rear wheel is lined up. Space the rear wheel so it is lined up with the front. Now you can put on your front sprocket and chain. Take a straight edge and see where you are at. You might need an offset sprocket for the front.
