I'm using the rear wheel of a DR 350 without damper, you need it complete because you can't change the brake disc (4 holes DR, 6 holes DRZ). On the left side DR distance part on the right side DRZ distance part + 1 - 1,5 mm distance washer on each side.
The DR's all got the same swingarm, so I think you can use a rear wheel with damper too - but I haven't tried so I'm not sure.
In opposite to franck I would say that you can't use the DR front wheel - I tried but it didn't work because the DRZ front axle is thicker than the DR axle and there is no bearing with the outer radius for DR AND inner radius for the DRZ axle. ( so I'm using the complete DR front in my XT 500 )
hope you can read my english for runaways
