Lobux,
I am thinking about getting bushings. Will the bushings make the steering feel more precise or just improve tire wear?
Thanks

I'm still trying to figure out how you guys all think you're smarter than Lexus after they improved the lap time at the Lightning Lap of VIR by 14 seconds with the changes to the 2011 and 2012 models. Really, you're going to bolt on a bigger sway bar and the car will be faster? Don't you think Lexus would have done that already with the other changes they made?
Suspension is a symphony and changing any one instrument impacts the performance of the entire system. I would approach this with great caution considering the vast improvements made in the 2011 and 2012 models. Stiffer is NOT always better, just as lower is NOT always better.
Right now the only thing I can see changing on a 2011 or 2012 without any hesitation are the LCA bushings.

I'm not able to speak to it from experience just yet, but it should do both. The only possible downside is the car won't trail brake into turns as nicely as it does with the stock bushings. But even that, I can't speak to because I haven't put bushings in my car yet. I'm still waiting for the NVH report on the solid bushings as I know they'll definitely be best for handling.

I completely ruined my Eclipse. I had sweet setup Koni Yellows, Eibachs, DC sport strut tower bars front and back, thicker sway bars .........sweetest setup, than I swaped the bushings (energy suspension) , the car became so glued to the road = so insanely bouncy it was unbearable. Even my adjustable Koni's were useless. I guess the only happy ending was I traded my Eclipse for my 2010 ISF

The bushings that come with the rear F-Sport bar are described by Lexus as:
As I have said in a previous post, I have the F-Sport bar and on installation I noticed that the bushings were in fact harder than the stock bushings.
I also have the 245/285 tire setup (Bridgestone S-04 Potenza Pole Position) and with this setup I have virtually no understeer. My bar has been on three and a half years now, and it aint goin' nowhere. It was one of my better decisions

The bars are finished in F-Sport blue and come with high durometer replacement rubber bushings that are harder than the OE bushings so there's less deflection at the bushing mount.

Lobux,
Thanks for your input. What are your thoughts on the ride becoming too bouncy? My car is my DD.
"Are you talking about polyurethane bushings? If yes, these are definitely for non-daily driver car.
I completely ruined my Eclipse. I had sweet setup Koni Yellows, Eibachs, DC sport strut tower bars front and back, thicker sway bars .........sweetest setup, than I swaped the bushings (energy suspension) , the car became so glued to the road = so insanely bouncy it was unbearable.

It's a symphony. Saying the Konis would not accommodate just means the change was bigger than their ability to adjust. The reality is, damping isn't the fix for suspension, it's a band-aid if your spring rates are too low. Removing the rubber bushing compliance just means you have to re-calculate everything.

I complied this chart about three years ago when I put on my F-Sport rear bar. I used Lexus parts information and actually crawled under a number of ISs to be sure that the chart is accurate. You can see by the chart that the F-Sport rear bar is bigger by 2mm as indicated above and the front bar is the same OD as the stock ISF bar.
As far as it working, You can doubt all you want, but it did make a difference I could feel. Your right numbers don't lie, and the chart proves that. And as far as the change being "all mental", you're the only one here who has expressed that opinion, and you have no experience to back up that statement
