Kev, let me try to clear this up.... 
  
I've already ordered the wheels in 9.5" & 10.5 as I really want one certain set. 
  
Rays wheels don't only come in +22 according to the catalogue (well the ones I'm getting don't). 
The supplier is waiting for "best offset" but I can get the following offsets in the right wheel/size. They have come back and recommended the smaller wheels.....  
  
For 10.5": -15, +5, +17, +30 
For 9.5": -9, +5, +17, +30, +42 
  
Now the standard Rays on Zed are +30 front and +33 rear.  
  
So from what you are saying, i could go for a +30 rear and either a +17 or +30 front?? What would be best there then? 
  
Alternatively, I could go with a 8.5" front and have offsets of: 
 -2, +11, +23, +36. 
  
So if I went for the smaller wheels, then you are saying that +23 & +30 would be best? 
  
On standard ride height (at the mo) I don't want them to stick out a mile and look cheesy crap, or get pulled by the rozzers etc......  
  
So now what you think?
