First:
Proper lug nuts are important and when you buy aftermarket wheels you probably need new ones. Stock lug nuts have a ball type seating, which is very rounded. Most aftermarket wheels have holes that are not suited for ball seatings, and instead, require cone seatings, which have a steeper angle to them. This allows them to be tightened farther onto the stud so they will have more contact with the wheel and actually contact the hub like they are supposed to. If stock lugs are used they likely don't have much contact with the wheel or hub and as a result can work loose. I originally put stock nuts on my new wheels and was shocked at how easy it was to break torque on them later on, much easier than with my stock wheels. It was rather scary as I only gave a slight push to each and they gave way.
Now maybe this is common knowledge but I certainly didn't know about it until I thought about getting new lug nuts for fun and read a thread about this issue. After my personal experience I am convinced this is true. Fortunately most aftermarket lug nuts have cone seatings so go get some if you don't have any, especially if you race!
Second:
Hubcentric rings. I have seen several threads in here about them and just want to re-recommend them. From everything I've read Honda wheels are hubcentric and not lugcentric so if you want your wheels to be perfectly balanced you should buy rings for your aftermarket wheels unless their bore size is equal to the Preludes (64.1mm) and most aren't. It's doubtful that your lug bolts would shear off but it may cause vibration at high speeds.
There are many different sizes of rings so make sure you contact the wheel manufacturer for their bore size. For example, there are even differences as small as 72.6mm and 73mm rings, although I'm not sure .4mm makes any performance difference. Maybe we could start a little listing of known sizes. For example, I found out that Rota has several different bore sizes. The two that are applicable to us would be 67.1mm and 73mm.
I know many people already know this stuff but for people new to wheels, I hope this provides a little insight.
