yup I would install a set for better handling braking and turning ! Not inner tires wear.

Why would you jump to conclusions that the OEM LCA bushings would have to be defective and that Lexus would then be selling lemon cars? The soft OEM LCA bushings are designed for comfort in mind. Higher rated durometer bushings would increase NVH which is not what the average Lexus owner wants.

FIGS and RR-Racing proved that dynamic toe changes is a very common issue on multiple Lexus models and will help prematurely wear out the front inner treads. Stock toe settings is another factor for increased tire wear. We have years of historical data on the CL forums that have already addressed that these are the main culprits for the front tires wearing out prematurely and that you'll have to adjust your toe setting to zero and upgrade your soft OEM LCA bushings to higher durometer versions to reduce dynamic toe changes while braking or cornering.

There's multiple threads on the 3IS sub-forums with owners exhibiting heavy inner tread wear on their 10k-15k mileage Lexus while stock. You even replied in one of these threads so I'm not sure how you missed not knowing that the 3IS still have this issue?

Re-read what jkonquer posted earlier as he too has repeated this multiple times but for some reason you are not comprehending...

Do a search for "inner tread wear" on the 2IS/ISF/3IS/RC sub-forums, and read the years of threads on how common it is for the front tires to wear out prematurely along the inner tread that plagues the majority of owners, even at stock height and alignment. Afterwards, read about how CL owners have resolved this issue and having even wear at the front tires again (hint: it has to do with adjusting toe to zero and upgrading the LCA bushings...).

lol at this thread

@jkonquer just get the bushing and call it a day and don't worry about what these people are spitting out.
deep down inside you already understand and know it will help anyways.

The Front end suspension of the 3IS is essentially the same as a 2IS. Lexus did not re-engineer anything up front.
For the front, all the bolt points are the same and the suspension and brakes can be interchanged between the two generations. So tire wear from that bushing that applies for 2IS will apply for 3IS as well.

Lol at this thread as well, I have never met anyone like that ever in 18 years of car forum surfing.

Yup, ordered and installed. I'll be getting new tires soon along with new alignment. We shall see.

Anyway....

The installation of RR-Racing USRS was pretty simple and a breeze. Total time took about an hour. Setting up and getting all the tools ready took more than the actual install.
Only hiccup was getting the preload set to the 0.020" gap correctly took several tries until I "felt" satisfied. Everything is torqued to the spec and will be re-checking them in 500 miles. BTW, stock bushings are super soft. I was able to move the washer in the bushing with my finger with ease.

The steering feels solid and firmer, no more of that wandering steering in straight line. The braking feels firm and over all car feels more alert. It does generate more feedback to the steer wheel which equals to more felt bumps and imperfections on the road.

I haven't had the time to push the car since I need new tires. So a full review will be coming.

any updates?

So i put in about little less than 1000 miles on the new Michelin PIlot Super Sport and haven't seen any toe wears so far. It is probably is too early to tell any noticeable wear. I have been driving pretty much the same and steering feels still good. The tires helped out a lot as far as responsiveness goes.

Just wanted to post and support jkonquer. I had inner tire wear on my 09 IS250 but was corrected with FIGS LCA. The steering felt straighter and firmer after it was installed.
Now that I am trading in for the 3IS, sad to hear that this problem still exist and I have to purchase another set

I have 11 k on my 17 is300 front tires show No Wear at all...

That is good to hear! Was there any changes to the 2017 AWD facelift models that Lexus did to reduce the front tire wear? or maybe AWD models have less noticeable inner tire wear because of the drivetrain?

ttsport15

I'm not sure but I seem to be amune

jkonquer

yes, the awd models are less prone to it. Since front wheels are turning and pulling and not dragging like on rwd. Although i didn't notice the wear until about 15k miles.

Ever since noticed the wearing problem, I have talked and physically verified with several (maybe 4-5 by now) RWD 3IS's and they all had the issue and not one of them knew about the wear. We don't see much Awd in socal.

jkonquer

thanks for the vouch,

As you could see from this thread, well at least "certain people", aren't very educated on the topic. It took me several days to actually pin point and disgonse the issue. And this is the main problem with lexus is that many owners take their car to the dealership, The dealers just say it is due to the vehicle being a performance car and not tell them about the issue.

Back to the topic, 3is shares same identical front suspension as 2is and other models. They all have this issue.

is there a cheaper alternative like swapping out the bushings to polyurethane ones instead? the entire unit with the billet bracket is quite nice but also pricey.
