Sparco seat mount vs Buddy Club

Does a Sparco seat mount weigh more than a Buddy Club seat mount?

In my quest to save more weight on my 2013 Scion FRS, I had to find a lightweight seat mount. The Sparco seat mount turns out to be very heavy. My Sparco EVO race seat with the Sparco mounting kit weighed just as much as my stock seat! I had to come up with a better solution. I searched around until I came up with another option. The Buddy Club seat mount appeared to be the best option when trying to save weight with a race seat setup. Once I had both products in hand, I set out to find out exactly how much weight savings was to be gained by switching from the Sparco seat mount to the Buddy club.
