Wheel offset

Some cars are designed to use a 1,2 degree offset. What this does it changes the center point of the tire when looking at the width of the tire.
If you mount a 0 degree offset tire onto a car designed to use a 1 degee offset wheel,the wheel may rub on the inside near the rear upright. This also changes your track width when you use different offset wheels. Hope this helps. There is a graphic online somewhere that explains this much better than I did.

Can anybody explain the different between 0 and 2mm offset when the offset is in the wheel and when it's in the hex? the overall geometry is the same on the car, the only difference that I can think of is that over the long 30mm worth of wheel, the 2mm offset would be stronger and create the feeling of a stiffer wheel.

Not sure what you are asking. but the offset is the position of the hex in relationship to the center of the tire just like the picture. I believe an offset wheel only purpose is to allow full suspension movement when cornering without the worry of the tire rubbing on any suspension parts. Just remember if you change to an offset wheel your track width will change also. Some cars where just designed to use an offset wheel (ie Mugen MTX-3)

Track widths are also be changed buy using different offset rims
Which also changes roll centers
this can also be used as a tuning aid

More offset with a same total trackwidth on the front will give more on power steer

I've had a kyosho team driver tell me that offset in the wheel or the hex feels different, but I can't seem to work out the geometry other than the wheel is just stiffer because of how wide it is.

The offset on the frontwheels will give a more changing wheelbase in the corners, the outside wheels will get a longer wheelbase and the inner wheel a shorter.
Offset is always made on the axle with shims, thicker hexmounts or other wheels

Is that true if the offset is in the hex, or if it's in the suspension though. shortening the pivot balls will change your roll center which could give you that feeling.

Something also to think about is contact patch and camber relatvie to a zero offset and +2mm offset wheel. Which one has a greater contact patch when cornering relative to camber setting?
I wish someone could get the info straight from the guy that designed the RRR. I think a lot of people have some good educated guesses as to why the car was designed this way, but it would be good to hear it from the source.
