Clearance between floor mat and gas pedal may cause pedal to get stuck. I assume this is with factory track hawk mats. I have those in a bag in my garage and used factory all weather mats. I never had an issue with them so far.
Yes, no clearance issues with pedals. My mats have a red border to match the Ruby Red interior. I would assume most others are all black. I run weather tech in a few other vehicles, but just wanted a extra set for a spare for now.
