Has any one had success with the Extend My Seat brackets? I recently purchased a set for my 2011 Sport. The brackets are too wide to fit. They rest on the centre hump and under seat vent, not on the floor. I contacted the support at Extend My Seat but I get only stupid suggestions; i.e.: turn the bracket around, or switch it left and right. I would really like a couple more inches to roll back the seat but these don't seem to work at all. They were so expensive I thought they would be much better. I would like to hear from any one with some experience with these brackets. Picture are appreciated.
