It’s tricky to determine only because both cars have to be at equal height. Most of us have different aftermarket suspension i.e springs or adjustable coilovers .
I mean we could measure the distance from the mount point to how low under the chassis the brace hangs. That would definitely show which one has more clearance. I will ask my friend Danny to measure his when he gets a chance as he has the Pierce.
Though honestly he has actually nicknamed his Pierce rock dozer. He has caught Rocks so many times with the Pierce that he has replaced it three times. Now he takes it off straightens it and puts it back on if its not too bad.
That speaks mounds ,
no pun intended.
I am actually gonna compare it the TB for clearance as another friend has the TB.
