Here are some more pics of the mods Ive done to my car--CF accents to front aero splitter and side sills (sills match the BMW M performance pkg), painted calipers, rear window spoiler, and MOMO steering wheel cover with CF accents (much better than the cheesy Pep Boys steering wheel covers!)

f sport rear sway and a square wheel/tire setup. virtually eliminates the annoying factory understeer.

Mine would be the Vais Ivic, sure can be a pain sometimes but having android integration for music and the occasional videos through the factory system has definitely improved my time in the car.

Me, too. I don't know why Lexus put such a wimpy sway bar in the first place.

Yea I was surprised too when I saw how skinny the stock sway bar was, looks like I could bend it with my hands(of course I couldn't) but it looked like I could....lol
The f sport way bar looks 3-4 times the diameter and very heavy.

Curious why you wouldn't do both sway bars.

If you do a search you will find most opinions here say just the rear is good enough, the F Sport rear sway bar has a 150% increase in stiffness and the front only a 6% increase.
So you can save $200 by not getting the front sway since they will not make a noticeable difference on the street, unless you take your car to the track for racing you wouldn't notice it .... but you do notice a dramatic improvement with the rear sway bar.

I tend to disagree with the 6% increase that Lexus quoted as the original F-Sport brochure and website once had the front stiffness increase rated at 42%. The stiffness percentages for the other models also became even more confusing when the % chart was revised.

This thread perfectly summarizes the benefits of both the front and rear F-Sport sway bar and whether or not you should be just the rear or both:

Interesting article. Now for a newbie question. I have a 2015 IS 350C F-sport. From all the reasearch I have done all I really have is the F-sport suspension and not the sway bars. I also am trying to find out if the F-sport sway bars...front or rear will fit the vert since it appears to be different than the sedan and is actually a 2IS even tho it's a 2015.
