Anyway, Reat seat delete for GRMN rear. To make it fit clean, the rear cover forward folding tabs must be trimmed 8cm. I would imagine the GRMN one is different/better.

Part No. 58570-52570-B0
Japan Retail Price: ¥43,890

Weight: 2.8kg

Stock Weights
Seat Bottom: 4.5kg
Right Back: 6.8kg
Left Back: 4.8kg
Hardware and lower Buckles: 1.5kg
Total 17.6kg

What's the increase noise like?
I suppose that foam underlay helps.

So all you need is that part to carry out the seat delete?

I can't tell any difference. Of course my car is pretty noisy, with Cusco mount and CR-S tires... :) But the noise you get with just a sheet metal interior isn't there.

As far as I can tell. It makes the interior look finished. GRMN side panels are the same, and even have the seatbelt holes. I believe the rear battery cover is different, as it's a little long to cover the rear seat gap.

That's interesting because I had a kit fitted that used timber sheets and I have to say it was very noticeable. It got to the point I could not put up with any longer and I removed it. I even fitted sound deadening in the rear section.
I am running the same Cusco mounts that you have plus the Cusco mounts on what "they" call the rear member sub assembly.
 
Finally getting the rear roll bar in and removed the rest of the seat belt and rear seat bracket hardware. Another 2.5kg out for a total of 17.3 loss after adding the GRMN rear floor.

I'm going to get this seat delete and a lithium battery once the Yaris graduates to track car next year.
