Did you set the proper tonearm spindle to pivot distance before mounting the cartridge?

Thanks, I'm not sure you can set the spindle on the JMW 10.5. The manual for the Classic 3 says something to the effect that if they didn't supply tool to adjust 'don't'. As I looked at it I really didn't see a way to do it either. I did remount the Zephyr taking special attention to how the wires were routed and they don't seem as tight. I'll probably call Mike at VPI this week.
You're doing something wrong. I own a Classic 1 w/ Classic 3 wand upgrade. I also use the SS Zephyr. I'm looking at my set up now as I write this post. The front face of the Zephyr is set back maybe a millimeter from the front end of the wand. Plenty of room for the wires. I used the VPI alignment jig, which btw is based on Baerwold geometry. Double check your work, but if you're still stumped, call Mike at VPI. FWIW, the Zephyr mates really well with the Classic wand. If set up properly, your rig should sing. Give my regards to Mike.

Stringreen, yes, if he used the vpi jig he will ultimately get the proper spindle to pivot distance but if the initial spindle to pivot distance is incorrect to start, then a radical cartridge adjustment within the head shell would be required to compensate for the incorrect distance.
Nedmoto, take the wand off the base and measure the bearing point to the spindle. You should get a distance of 262mm. If the distance is greater than 262mm, that is why your cartridge needs to be place to the rear of the head shell to compensate for the greater length.
Another simpler explanation could be that you are using the 10.5 jig setting instead of the 10.5i jig setting.
I did speak with Mike today. He said he's probably mounted about twenty Zephyrs and they do sit far back in the head shell as far as I previously mentioned. He didn't real have any explanation why SS designed it that way, and he too thought it was odd since it was designed for VPI. I measured the bearing-spindle distance and it's the 262mm mentioned. I took a picture (wish I could post it here) and sent to Mike so he could see it.
I've figured it out (I think). The issue is the distance from the cart's mounting holes to its stylus tip. I just held another cartridge up next to the Zephyr and it's obvious that this distance (in the other cart) is less than it is on the Zephyr. So, to compensate, the Zephyr has to be moved back in the slot.
