OEM Seat assembly from my 2006 WRX TR weighed in at 43.5 pounds
The SPARCO bracket with YANAKA seats weighed 35.8 pounds
1) The seat sits a little TOO low for my liking. Before I do the drivers seat I have to search for some bushings or spacers to raise the seat about 3 inches or so or else I aint putting it in. I mean it!
2) The bolts are a real p.i.t.a. to put back in once they're out BUT at least the Bracket lines up perfect with the floor bolt holes; however... of COURSE the sliders that came with the seats did NOT.
3) I had a nice time doing geometry & algebra before I marked the spot to Drill properly measured & placed 3/8 holes through the Steel bracket. Yeah.. great.
4) I did have to cut out some rug from around the front bolts to get a better fit though. Also, I had to hit the Hardware store for 8 sets of grade 8 automotive bolts/washers/nuts to connect the bracket & sliders.
FYI.... the SPARCO bracket was ordered from Andy's Auto Sport Body Kits - Your Body Kit Superstore! on March 19th; it was NOT delivered to me until June 8th.
Thats 81 days later!!! Shop with Caution.
All in all... Im Happy with the final result.
