Before they had there's, XV had their own system, ours works a little bit better....
Do you have some data or competitive testing to draw that conclusion?
I did look at XV before ordering the US Car Tool parts. The pricing was close, but XV didn't offer [at least from what I saw] the torque box set, which I need. I had to make one order and pay shipping from one vendor.
The engine bay brace is a nice piece, but I will be building my own for my car.
