Actually in Sport mode, the front stiffens up 90% and the rear stiffens up 50%. Atleast that's what the tech at Lexus told me. He attended an ISF driving school prior to selling it to me. Let me know if you've heard otherwise...

I highly doubt the suspension adjust in sport mode. it is not user adjustable on the fly. Tech probably was refering to the IS-F versus a X50IS. But even still 90% up front would rattle the engine out

The only thing that adjust in sport mode is tranny and engine for a more sportier ride and feel.

From Lexus's web site.

"In addition, a Sport mode switch on the dashboard allows the driver to select from among Normal, Sport and Snow driving modes. In Sport mode, the VDIM system allows higher dynamic thresholds before intervening, alters steering assist to increase steering weight, and throttle response is sharpened. With the transmission in D mode, gears are held longer in response to throttle input."
