I've been cleaning up the interior of the Boss for HPDE and track day duty Since I don't drive on the street anymore I removed the passenger seat, center console, radio/HVAC panel, etc. I don't want to completely remove the interior in case I decide to go back to stock (unlikely) so I left the carpeting and headliner. Do I need to leave the E-brake handle and cables? I only use it now after loading it in the trailer. Removing the cables looks like a chore so I will likely leave them as is but the handle won't be a problem. Do pure race cars leave them? I don't recall.
