So im looking into the rear sway bar and ive been reading different options. The end result is their are 2 sway bar for 2nd gen IS, mostly everyone that has used aftermarket bars has confirmed perfect fitment, now my question is can anyone confirm f-sport rear sway bar fitment?
As far as i know north america cars (mine is canadian 2011 350 fsport)
we have a curve in the bar in the middle unlike all the picture of the fsport bar which is straight.
Anyone that has done rear sway bars can you confirm you brand and fitment please

this was a Australia thread

and mine does look like the stock oem with curve

 

All the factory bars have the curve. Some of the aftermarket bars have the curve, but most do not.

For your car, it doesn't matter, either will fit just fine.

Only cars that have full sized spare tires require a bar with the curve.

Jeff is correct. It is my opinion that a bar without the spare tire curve, all other things being equal, would be stiffer than the bar with the curve. I don't believe a test has ever been done to prove or disprove my theory.

I have an ISF, and have had the FSport bar for a few years now, and I remember the improvement I felt after the install.
