FWD and RWD rim diff
Just wanted to know what the diff is between fwd rims versus rwd rims. Was looking at some gs400 pics and ran across a black GS owned by gentlebouncer. Awesome pics by the way (gentlebouncer), really like the 20" Giovanna rims he has on it so did some surfing on the Giovanna Attack rims and they say it's for fwd cars? Are they interchangable then since GS400 is a rwd car?

well in terms of the rims themselves, there is no real difference between rims "for" rwd or fwd.
if anything, the difference for rwd is that you can go with staggered setup, where you can have narrower width in the front and wider wheel in the back. this is better for accel and handling. for fwd, this is totally not necessary, since you are doing everything with just the front wheel. so for fwd, you will do the same width front and back.
and of course, on top of that there are all the offset and fitment issues

Most of the wheel online shops say whether the rim is for a FWD or RWD instead of saying whether its for a truck or a car. most of the online shops must think most cars are FWD...
But on a different note, I have a set of Giovanna Attack's off of my GS3 for sale. I just shot you a PM Tim.

Most companies like Giovanna, only make their 1pc cast wheels in 2 or 3 offsets. For instance, it may be 38 offset (most Japanese cars like Lexus, Infiniti, etc), and then a 25 offset (M/B, BMW, some American cars, etc).
The thing is alot of people dont understand offset when its posted in numbers, so its easier to say FWD and RWD. The FWD is the higher offset thats all.

Great question.....I had the very same question but didn't want to ask. I just thought as long as the bolt pattern, width & offset are correct for your car, the wheel will fit (regardless of whether the manufacture calls them FWD or RWD).
Derrick, so basically you're saying a FWD usually need a higher offset (such as +45, +50, etc.) and RWD cars usually have lower offset (such as +25, +30, etc.) right?
Also, another thing that is confusing as hell is this centric hub ring thing I've been reading about. I have no idea what they are......but some members seem to know what they are and when they're needed......I remember seeing someone trying to sell used wheels in the classifed section and a potential buyer asked if these hub centric rings are included. If someone can explain what these hub centric rings are, it'll be greatly appreciated.
Is there something other than the size, bolt pattern & offset that I should know about before buying wheels (especially used wheels)?

if you take off your wheels, you will notice the center hub bore at the top of the rotor head, there is a different size of that to every wheel. if you get a wheel with the right size, your wheel will be hub centric, meaning if you snap the wheels on, the bore will fit right on and you can start tightening the lug nuts
however if you get a wheel with a larger bore, the wheels won't be centered when you put them on. when you put on the lug nuts you will have to play with the position of the wheel for it to fit. that's called lug centric.
the problem with lug centric is that the wheels sometimes might not get 100% centered, and you will get some vibrations when you drive at certain speed
to correct the problem you put on the corect size of hub centric rings, which will correct the bore to the factory size. there are a lot of different sizes of rings
