I've tried searching for this, so forgive me if it's been discussed (and point me to the thread). I just got a 2013 350 F-Sport, and know from the Lexus descriptions (which are a bit non-specific) that the suspension and steering have be made more "sporty". But—what are the specific enhancements? Is the change to the steering the standard F-Sport ECU option (that would switch to sport mode when the PWR switch is engaged), or is it a simpler re-tuning? What are the specific suspension changes? Are they the same stabilizers that would be the add-on F-sport parts? I'm assuming the intake and exhaust are stock 350. Besides the obvious cosmetic changes to the exterior and interior, are there other differences?

Thanks in advance.

 

- Hope this help

 

For second gen is350 f sport was cosmetic with options you add on. Fsport springs. Fsport intake etc.
All 2nd gen is350 accelerate the same. Turn off traction. Brake torque to 1800-2000 rpm. Dont put in performance mode. Just keep the car in drive. Dont use paddle shifters. 0-60 from 4.7 to 5.2 depending on cars condition. And traction as well as tires

I think most second gen is350 f sport opted for suspension upgrades on option list
