Default Fsport Front vs. Rear Sway Bar

I thought I read on some thread that front f-sport sway bar doesn't add too much more than the OEM for the 350? Something like 6% better for body roll.

While it's the rear sway bar that reduces the body roll the most. Did a search, couldn't find that thread.

Just wanted to confirm that I should just get the rear for the best bang for the buck. Thanks.

FRONT:


REAR:

From what most people are telling me, you will definitely feel the difference when you add the rear one. And you may feel the difference when you add the front one. lol

Best bang for the buck, yea the rear will make a HUGE improvement. If you are any bit OCD, it will haunt you until you get the fronts to match LOL.

You will feel the difference in the rear right away. The front not so much. Both are great investments.

Every review I've seen from someone who only did the rear, then later added the front, has broken down like this:


Going stock F/Stock R -> Stock F/F-sport R= Very noticeable improvement in handling.

Going StockF/F-sport R-> F-sport F and R= ALSO a noticeable improvement, but not as large a one as the first step.

Overall makes me glad I have both.

I notice people say this for RWD, so for AWD people is it both very noticeable if you change them at different times?

According to lexus.com for the 2011 IS350 the front increases 42.8% stiffness and 151.5% in back.

Lexus.com/F-Sport information isn't always entirely accurate. The IS250 and IS350 both use the same sway bars. The difference in stiffness is actually between with and without Sport Package.
