I think a lot of people established the GT500 OEM STB wouldn't completely clear the hood or plenum on the 05-06 GTs. I have heard conflicting reports on 07-up.
Here's the BMR tower brace clears by about an inch..zero rub on plenum cover or my cervini hood..
Doesn't the ford racing stb clear the blanket and plenum? I have a ford racing stb, i have a plenum cover, but haven't instaled it yet.
I have a GT500 STB with no hood clearance issues on my 06, my hood insulator rubs it but no hood buckle, a friend of mine had a problem with the hood buckle but it was a easy fix by putting a washer under the brace on the 2 rear strut tower studs which angled the brace down enough to clear the hood.
