in case some of you are interested.

1. pop the seat cushion by pulling the seat upwards. the cushion should pop off easily. push the seatbelt buckles through the slots. the cushion now can be removed completely.

2. At the bottom end of the seatback, there are 4 black 12mm bolts that secure the seatback. one of each near the door and two of them are near the center console. DO NOT remove the seatbelt anchor bolts which are 14 mm. lift the seatback to free it from the three upper clips.

3. remove the C pillar cover. start from the lower edge and just using fingers to carefully pry them off. each piece should be held down by three blue plastic clips.

4. pop off the rear deck by lifting the front edge carefully. it's held down by three clips.

5. you now have access to the subwoofer or the brake light. the subwoofer is secured by four 10 mm bolts.

Can you weigh everything that was removed? Do you think the process is worth it on track days?

MicaISF

i didn't weigh the seat. the seat cushion feels like ~15lbs. the seatback should weigh 20-25 lbs. just my guesstimate.

in the IS350 caymandive hit 12.8 with slicks bolt ons and removing seats ( think the fornt seat too. so on the F you should hit mid-low 12's easy by removing the seats, slicks, etc. all this in cold weather offcourse

possibly. you need to consider that cayman races at what is considered to be one of the fastest tracks in the nation.

Is this correct? I am about to have my rear center tray wrapped in silver carbon. I was adviced to remove the seat to remove the tray........
I feel quite some resistance when pulling the seat upward, I would hate to break it

Could anyone confirm or tell me how to remove the bottom part of the rear seats.

- thank you in advance!

Never removed rear seats in either the IS 350 or the F, but I did remove the front seat in the IS 350 when I ran a 12.84@109. Temps were also just above freezing so the car was making very good use of the weather conditions.

Yeah any track that is close to sea level and is in a climate with cool weather will be fast. Florida would be great if you had a true cold season.
