Yep, there's a bump, but it's carpeted. South Carolina red dirt is hard on carpet though. So I was looking for something that matched the brake and gas pedal (it's an automatic). And as someone else already mentioned, the all weather mats do not cover the dead pedal section of the carpeting.
I bought a "dead pedal" for a Ford 500, not the Shelby. I just cut the tab off the back and mounted to the carpeted hump in the floor. They are only $7 or $8 from Ford, PN
