I'm curious what you guys who have lowered your coil-suspension Model S's have paid for install? The springs themselves are fairly cheap, but my local shops (even the one that track preps BMW and Porsches) are giving me the "OMG TESLA WHAT" line and quoting 1500-2000$ in labor. This is something I've done before in my garage (when I had one) without much issue, so I'm trying to gauge what the disconnect is here. And in that vain, anyone in the Portland/Seattle area want to help a brother out? Thanks!
