F Sport Sway Bar set installed UPDATE
I'm looking to add some additional enhancements in driving and stability for my 2010 IS350 with stock suspension, and wanted to find out about other people's experience with the F Sport Sway Bar set (Part number PTR0253094). Also, can it be installed with the stock suspension with no issues?

It's a worthwhile upgrade as the sway bars greatly increase roll resistance. You can definitely use them in combination with the stock shocks and springs.

They say it improves steering and braking by eliminating excessive movement in the lower control arm bushing. Lets see how these work out

Along with the F Sport Sway Bar, I also bought RR Racing's Ultimate Steering Response System which is a Lower Control Arm bushing and housing upgrade Product Code: ISFXLCA001

How about upgrading the steering rack bushings while you're at it? I'd recommend the Fig Engineering polyurethane bushings for the sway bars as well..

My First mod on my car. They're definitely worth the money.

The document from Lexus regarding the stiffness values of the suspension is useful but maybe less useful than it should be. The sway bars on the IS250 and IS350 are the same, but the increase in stiffness values in the chart are different. I suspect the values are actually with and without sport suspension for 2009-2013 sedan models (as 2006-2008 models used the same sway bar with and without sport package), but I haven't been able to verify the exact details.

I've got the very same set on my car; got mine to help with the inner front tire wear as that continues to be a problem on my car (mainly for the way I drive it...HARD ) But it has helped; the wear isn't as quick to wear down the tires. All this even still after numerous alignments throughout its life.
The only downside to these bushings is the increase in harshness due to irregularities in the road causing vibration (e.g. brick roads, etc.).

So would you say NVH is significantly increased? If so, how bad is it? The reason I'm asking is I drive a lot between Northern and Southern California, and some of the roads I hit doing the 370 miles can have a lot of imperfections. 8 hours of a vibrating steering wheel could get tiring pretty quickly

I've modified the original F-Sport brochure document to what I believe is what was intended to be displayed on the chart for the IS RWD, IS AWD, IS-Convertible, and GS models. They all show a 1:3 front/rear ratio of improvement over stock.
Coincidentally, I'm in the middle of swapping out the stock sway bars with the F-Sport sway bars on the second IS that I have (IS350C). I can try to measure the stock sway bars of the IS350C to see if these figures do have validity. So far, I can attest that the IS350C front F-Sport sway bar is noticeably heavier than the OEM front sway bar. Once I get the rear bar swapped this weekend, I can provide further input.
