  1. Great Weight Reduction

    Posted by William Scott

    When I saw an online install video that noted the install of the Grimmspeed PC680 would take 47 lbs off the driver's side front, it was a given I'd have to install the battery and mount.

    Install was very easy but I found that the battery moved around enough that it wouldn't pass a tech inspection. I purchased some foam tape and applied it to the bracket in spots that it would come into contact with the battery, problem solved.
