There's no shortage of push in the stock IS-F. I found that out at the Lexus Driving Academy on the half day session. You'd never know if you only attended the free sessions. They never let you go fast enough.

I don't think the F-Sport wheels will fit on the IS F. Check it carefully before you buy them. The F-Sport wheels were designed for the IS350 and the brake calipers are different sized between the IS F and IS350. The stock IS F wheels won't fit on an IS350 either.

The F-Sport brake kit is not the same as the stock IS F brakes. Anyway, I was talking to someone at the JDM show who told me he tried to put the stock IS F wheels on the IS350 and they didn't fit. So it's second hand info but I have no reason to doubt him.

I don't doubt the ability of the bar to improve handling but why would Lexus release the IS-F with the bar it has if they had another bar that performed better?
My only guess is that I don't have trouble inducing oversteer when I ask for it and though the initial understeer may be reduced with the F-Sport bar it would make the throttle-on oversteer worse. So for the street the F-Sport bar may be better but if pushing hard the stock bar may be better.

I have not run across any pics of a F-Sport sway bar installed but this is what it looks like.
FYI, Sewell is still running the F-Sport promotion. The price after putting in the discount code "F-Sport" is $177.19

Are the F-Sport Bilsteins Shocks already installed on the F from the factory??
Online specs call out a monotube gas-filled shocks absorbers only-no brand like the Brembos?
Thanks!

No. The F-Sport/Bilstein shocks are Lexus USA accessory parts. They are designed for the US Spec ISx50. Toyota/Lexus vehicles manufactured in Japan are usually sourced from Tokico or KYB for OE applications.
