Could anyone let me know torque specs?

I asked these info local lexus dealership but they don't want to let me know the specs

F1 - The diagram isn't clear enough which bolts. The yellow circles look like the control arm bushing bolts, and the red circle looks like one of the two steering rack bolts. Would need to validate which ones they mean. If they are what I think they are:
Yellow circle - 135 N·m {1377 kgf·cm, 100ft·lbf}
Red circle - 118 N·m {1203 kgf·cm, 87ft·lbf}

F2 - Green circle - 204 N·m {2080 kgf·cm, 150ft·lbf}
Yellow circle - 86 N·m {877 kgf·cm, 63ft·lbf}
Blue circles - 50 N·m {510 kgf·cm, 37ft·lbf}

R1 - Yellow circle - 127 N·m {1300 kgf·cm, 94ft·lbf}
Blue circle - 19 N·m {195 kgf·cm, 14ft·lbf}

R2 - Green circle - 127 N·m {1300 kgf·cm, 94ft·lbf} (Same as Yellow circle rear)

Any updates on these? a buddy of mine is planning to do this on his s2000 as spoon has a kit , so I wanted to see if anything would turn up here for the Isf, which brought me to your page

Let us know if you feel a difference .

Here is a video from Spoon Sports

Has anyone on the forums installed this kit on their IS-F yet? The OP of this thread hasn't responded back to provide feedback.

I recently learned about this product and I'm curious to know if the Lexus IS platform can benefit from this as it does sound interesting in concept.

Also interested in feedback on the Spoon Sports collars as I'll soon be removing the front crossmember.

Do these replace an oem part? If so, what's it made of?

Thanks in advance.
