E46 M3/Z4M - DSS Axles 1000HP

I have a set of DSS Axles for a E46 M3/Z4M, less than 200 miles on them, never ripped on.. they're coming off a build that was never finished. I'll need your cores. No need to wait 2 weeks from DSS, you can have these in a matter of days for 40% less than new. $600 + Shipping.
