No secrets here.
I just got a call from my supplier, who remembered I mentioned concern about the rubbing. He had just been in contact with Paxton. He asked me to send him my serial # off the Paxton, and that he would get back with me.
Nothing specific, but it sounded like Paxton was working on a solution, and should have something to address the rubbing concerns.
I would expect Paxton to release an updated housing.
As a side note, I am very happy with both the quality of the installation and the huge improvement in drivability with the Paxton system. It totally transforms the car up to world class power delivery.
