Nope. These are OEM Lexus F Sport Accessory line of optioned parts. F sport cars have an upgrade sport suspension and some aesthetics but don't come with any of the F sport accessories. F sport accessories come in blue so it's easy to tell whether the car has F sport parts or not.

Also anyone got the part numbers of the f sport front and rear bars and if needed relevant bushings etc to fit? My 2is is only a humble european diesel variant (2.2 turbo diesel, 300lbft/175hp stock with 6 speed manual) but this f sport version i recently bought is going to get a little more done to it than my previous is220d SE which i managed to get up to 383lbft/231hp, coupled to the 6 speed manual and having done some basic brake upgrades it hauled *** on our twisty roads here and decimated is250's (no is350 here).
Looking to do much the same with this f sport is220d i now have but wanting to do more this time around and also to a higher standard since theres under 300 is220d f sports (all colours, less if broken down by colour) in the UK.. Plus its a cleaner car than my old SE was to begin with so i dont feel bad buying the good stuff (f sport gear **** and lower airbox on the way already).

Whats the deal with the 06-08 only and 09 only? Are different bars used in the old models than in the mid generation and late generation facelifts?
i suspect lexus UK should offer the bars but they may come up as TRD parts instead of F Sport. Checked availability of the F Sport lower airbox via part number with my nearest dealer and it came up but nothing but basic description and listed as a TRD part.
Ill have to borrow a vernier caliper and check what the stock is220d bars are. Traditionally diesel engines are heavier so might have a stiffer front bar than some of the stock ones quoted in that brochure pic.. Then again the is220d engine is nearly all aluminium and only 4 cylinders so may actually be lighter than the V6's?

I wonder why there's a discrepancy in the numbers for the IS250 AWD... especially the rear with 188% vs 42.8%!!! Regardless it's good to know they are actually way more stiff than I initially thought since it's been hard to believe it was just a ~<50% difference after the install.

I have just the rear straight 19mm bar on my AWD. Maybe that one gives the 188%, and they forgot to update the numbers. I need the front one though. I can definitely tell it's lacking in the front now. I just don't want to spend $400+ to get it buying the complete set.

Can you elaborate on this? I am getting ready to order the rear bar for my 2009 IS350 RWD which does not have the sport package. What else do I need to order?

I think I found the answer to my own question about 20 pages back. 2009+ need 2 rear brackets, 48832-30060, and 4 bolts, 90119-A0169.

just installed the rear on my 07 IS350. it was really straightforward as I soaked/drenched all the nuts and bolts in PB blaster overnight. I put the rear on jackstands, loosened the 17mm end link bolt with a 3/8" breaker bar, put a 5mm hex socket into the end link bolt while removing the 17mm nut, and the rest was easy. the car feels good!

Jeff - I'm sure I read most of this thread many years ago before I bought the F-Sport rear sway for my IS-350. I understand that it's compatible with the 2011 IS-F I just bought, but does it offer any improvement to what most consider a vastly superior setup over the '08-10 suspensions? I do plan to track the F, so definitely want to swap rear sways if it makes sense to do so!

Newb w/a 2013 IS350 Fsport. It appears to understeer but being's it is used and has Dunlops on front and Nitto's on the back 225 / 255 stagger that could easily be a huge factor.
I measured the bars with veneer calipers:
Front = 28.5mm
Rear = 15mm. And the rear has a mid section turnout looking a lot like the ISF bar.
My question is, will the 48812-30400 ISF Anti-Sway Bar from 2008 - 2014, fit the 2013 IS-350 USA model?
Ride quality matters but matching the ends would be a blessing if in deed the ISF is in between the stock 350 and the F-sport torsion rate.
Thanks in advance...

I have a 2010 IS250 AWD and just purchased the F sport sway set. I have been reading up and am very surprised that there is now DIY with pics to install them. Sure the rear is basic, but the front I am concerned about.
Can the front sway be install on just ramps in my drive way?
I have read that the lower subframe needs lowered and you have to "mess with the steering a bit" so I am concerned about doing all this on ramps. Is the subframe on our cars just a brace? Or does it provide the mounting points for the suspension and I am going in over my head. A PITA is fine with me, I just need to know that its actually possible to do in my driveway with just ramps and wrenches.
Also, on a lot of old threads, I see a link to the instructions to install it bu Sewell is gone now and the link no longer works, anyone have the PDF?
On a side note, with the sways being my first suspension/chassis upgrade, what should I look at next? The rear brace? FIG bushings? Coilovers? Bang for my buck is paramount.
Thanks in advance

FIGS Front Lower Rear Arm Mount #2 LCA Bushings 90 Duro High Performance a/ FIGS billet and/or F-Sport Rear 5 point Chassis Brace ---- these both made huge huge differences with zero negatives IMHO. The rear brace is why I personally believe is the part that re installed confidence driving over 80mph on the freeway in these cars.
