Sway Bars for the F?
Hi Guys,
To me it feels that the suspension in the F still has some significant room for improvement, especially in regards to the amount of body roll and amount of understeer. I've heard that the F-Sport Rear bar (19mm compared to the stock 16mm) helps a little with the understeer. However, I was looking for a more complete package.
I was wondering if anyone knows if the regular IS250/350 sway bar sets are interchangable? The reason I ask is that it seems that Hotchkis Sway Bar set for the IS250/350 maybe a great upgrade for us if it fits. The front is 32mm vs the stock 29mm, and the rear is 19mm vs the stock 16mm and is also adjustable! Below is the link to the product at L-Tunedparts.com :

the stock is 17mm and shaped differently. the F sport bar is straight and 19mm. i just put mine on tonight, after a short spirited drive, i say it's definitely worth the money. the car is a lot more neutral and feels more responsive and steers quicker. THIS IS HOW THE CAR SHOULD HAVE BEEN EQUIPPED FROM THE FACTORY.
the stiffer sway bar did make the ride a bit more rough especially on uneven pavement. i like firm ride, so it worked out well for me, but for those who feel the F is already a bit too harsh, this is probably not a good mod.
i bought mine from superstition springs lexus in arizona for $ 175 + $16 for shipping. installation was easy and took about 30 minutes without any help. try their ebay store for the best deals.
i didn't take any pictures. it's a beautiful blue bar, but once installed, most of it is behind other major suspension parts and there is really not much to see.

F Sport Rear Sway Bar Part Number
Is the rear F Sport sway bar that everybody refers to the bar that is actually made for the IS250 AWD? Is PTR02-53080 the correct part number? As long as I am under the car, does anybody know if the rear chassis brace will fit with the Joe Z exhaust?

See above comments in red.Is the rear F Sport sway bar that everybody refers to the bar that is actually made for the IS250 AWD? Is PTR02-53080 the correct part number? YesAs long as I am under the car, does anybody know if the rear chassis brace will fit with the Joe Z exhaust? I don't know, but from all I've heard in the IS community, it doesn't add much stiffness, and I believe the F already has additional stiffening in the rear chassis area.

So both the front and rear F-Sport sway bars... fit the IS-F? Because if I have them both I'm going to put them on as a set. Got to make sure I have the right amount of blue under the car.
^^^^Yes they do. However, IMO, it is not necessary to change the front sway bar on the F. It is the same shape and diameter is the F-Sport bar, 28.6mm. The paint color is different however, black vs blue. I don't know if the bushings differ or not.

the bushings are different... rubber to poly... so it doesn't hurt to give it a go...I like to turn the wrenches^^^^Yes they do.

I was going to say the same thing. The front sway is going to be a BITCH to replace because of all the twists and turns that you have to do to get the bar through.^^^^Yes they do.

I was looking for a larger front sway bar and I think only Hotchiks makes a larger on at 32mm. But I know for a fact that going with too big of a sway bar, front or rear, definately takes away from driveablilty. This is why I just went with the Fsport rear sway only and it's absolutely perfect.
