What's the difference between a 45 degree side mount bracket for seat mounting vs a 90 degree? I see more 45 degree ones, but why is that better than 90 degrees? I will be getting a bucket seat for my P1-X, but I can't figure out why one or the other would be best for my use case? I like this one so far. As far as I can tell, distance between seat mounting piece that goes up and down and part that bolts into rig is the same, but the angle juts it out wider a bit, I just don't understand why. https://www.amazon.com/Sparco-4902-Black-Steel-Mount/dp/B00E5ZIMJW
