Sort of: R170 is the SLK230, 320 & 32 - Some of the smaller wheels will not fit on the SLK32 due to the larger brakes.
One note: Our SLK32 comes with 17x8.5 +34 offset wrapped in 245-40/17 tires. I think the offset 'might' be different from the XF. Just thought I'd throw that out there...
Another great website for reference when playing with wheel sizes:
Wheel Offset Calculator
Tire Size Calculator - tire & wheel plus sizing
The offset calculator really helped me when trying to find a good offset for dedicated drag wheels.
