- When it comes to steering feel and response, Lexus has pretty much always been behind other leaders in the segment such as BMW. But one thing you can do which really improves steering performance on the Lexus IS platform is the lower control arm bushings. On this episode, I show you how to do it and we find out if it's worth doing.
Bushings from RR Racing can be found here: www.rr-racing....
Checkout www.rr-racing.com
It's worth noting you can actually do this mod on any IS of this era. So IS250 or IS350 are capable of being upgraded as well. And it makes a huge difference, for not much money. rr-racing.com
alot of lexus part are design to wear out for quick fix.. little there and there just to made a littel money off the owner if you don't had eletronic fail.. which don't worth it for old car... you will be fine..
Or may be Lexus designed the car to have minimal nvh by using rubber? It is a Lexus after all. Any rubber will wear out after 12 years so replacing with OEM bushings would have been gain back the response without the harshness of the poly bushes. But since gear heads are smarter then Lexus engineers and they like to replace oem parts with aftermarket parts designed for the track to help the car perform “better”.
Love ISF but I got 08 IS350 with Intake, Header, exhaust, RR Racing Tune and next RR Racing bushing 😎👍
@@huck9293 Love the sarcasm.
@@Magicstockton lol I tried. Think about it. If poly really is better why would all car makers just use poly on all their bushings? Polys are actually cheaper than rubber after all. Kidz don’t know shit these days lol
Just installed these on my IS350! What a world of a difference, one of the best upgrades for the $!
I always felt like the reduce in the electric power steering assist when in sport mode made just enough difference for me with spirited driving.
Adding more front caster might help with feel.
Thanks for the video Kurt - Glad you are enjoying the upgrades!
Heard it makes a world of difference.
LMAO at the safety glasses remark
I’d rather look overly cautious than lose my sight.
/why are so many utubers such assholes; you could have said SAFETY is important????
Might be gay to wear safety glasses but it’s more gay to be blind.
I have a GSF and you can do this on that as well. Good video! Keep it coming! 👍
Thanks for this video...just installed these right now... On the floor with jack stands... Super easy and awesome mod
All the questions I had about this were specifically answered in this video.
1) is there better road feel ( I came f/ an audi)
2) How the preload was done.
The "Figs" don't require that adjustment it seems. hmm that creates another question for me, I don't know which to get.
Thanks for the great vid.

This car will become a classic in the next 10 years. I love that the price right now is below $3000 😍😍😍 I am getting one this week
Freaking thank you for posting this I'm about to replace mine. Xforce on mine as well, I'll keep a watch on your progress!
The biggest problem that I having with my dad is f is the electronics specifically in the trunk
Oh my fucking god!!! A Jordan Grand Prix flag in that garage?! Who is the legend that owns that?! Jordan have me some of my best memories growing up in the late 90s!!
Love my isf too 😎😎
Haha I posted a recommendation to you to do this mod when you first bought your ISF and complained about steering. You can also update your steering rack bushings with Figs Engineering bushings ($18), and update your steering ECU to a 2012 (try and find a used one, it will already be calibrated)
Good call homie. I like the RR design more than the FIGs but I'm sure both work well. It made a big difference
@@EatSleepDrive As I mentioned above, there are steering rack bushings you can replace from Figs engineering, they are very cheap and easy to install and will give you additional road feel. I have them in my garage but haven't installed them yet on my 2010 IS350, but it's on my list!
I think I recommended these parts before you did 😛
@@Pube83 No, no no, I posted .00003589 of a second faster than you did!

RR Racing USRS also help with inner tire wear 👍
I picked up a rc 350 a few months ago and I have been looking at these bushings. Power without control is nothing so I want to set up the suspension first and then supercharge the car. Great video thank you for torque specs!
Cheers. Enjoy your rc
Great detailed video, but you left out an important feature . . . the year of your car.
Hi, I'm from HK.
Thanks for your advice, I'll try to get one of these and try how it feels
Just did my LCAs today! FIGS 90 Durometer haven’t driven on it yet cuz I’m still doing my coilovers but I’m super excited
Enjoy!
I wish you go back again to the GT350 😍
Any idea if this could help with tear wear?
Did you get an alignment after? Heard many people say you will need one that have done it?
Nice upgrade, what other mods do you have planned down the road? Any cooling upgrades planned?
I don't plan to track it so as of now I don't think I'll need any cooling mods.
I just installed some over the weekend and now I notice rattling sound on speed bumps like my shocks are bad.....did you experience any of that? I used lub like in your video.
Show us a wiper blades upgrade 👍
On the GS AWD it slides right out. A tire is harder to change :lol:
The primary benefit is massively reduced tire ware due to toe out during heavy braking.
Are you referring to the inner wear due to the oem neg camber?
@@19Stifler91 is250 have this exact inner tire wear issue and replacement of these bushing supposedly corrects the issue.
@@19Stifler91 slight manufacturer negative camber in itself won't cause much inner tire wear providing the toe is properly aligned. In these Lexus cars, that bushing causes the control arm to move a lot, especially under breaking, which in turn leads to said inner tire wear.
What happens if the pre loads aren’t tight enough and the feeler gauge still goes through?
Wondering if you’re gonna fix the valley plate leak (if it’s not done already) lol
Does the problem come back once it’s fixed??
@@ronaldowaldo4267 eventually it will but not for a long time.
If m3 so good in communication why so many of them are crashed by loosing control and isf is not?
Thx you it’s helpful
I prefer figs, they have great reputation and long time in business. Heard some negative things about rr bushings, but rr said it was with one batch...idk i got figs bushings for long time, they are great. And you get grease in the package 😂
5:25 😂🤣
What tyres are in front? Perhaps changing them might help to get more feel?
The ISF needs some tuning to improve low end grunt. Especially since it has no launch control, getting outta the hole is slow.
A 5.0L V8 needs more low end grunt? Try down-shifting.
@@marekd.7350 if you owned an ISF, you will know its a high revving motor where peak power and torque is up top. 0-60 is in the mid to high 4 seconds. The IS350 when it came out did it in the same time and it had only 3.5 liters! I raced my brothers g37 and we were neck and neck up to 70 mph where I would walk away. This car dynoes 340-360hp and much less torque than you think. This car shines at 4-7k rpm. My GR Supra, would walk my ISF from a dig everytime. Take it from a previous owner who experienced this.
@@beexiong2995 100% agree. great car and I love mine but I wish the (fun zone 0-100km/h) was a little bit quicker, Low 4.1sec territory would have been amazing at the sacrifice of some of the top end speed.
@@j3str15 yup i just find people who know nothing about the isf say foolish things just because its a 5.0. Even the 5.0 stang gets some heat for low end grunt. Its power curve is similar to the isf.
Nice car
Let's goooo baby
My gs Awd now feels like rubber bands are holding the control arms. The bushings are all cracked :lol:
Keep it up
how many miles does she have?
134k
EatSleepDrive it looks great at 134k!
Thanks!
super easy barely an inconvenience
You need the 2013-2014 steering ECU.
Not the 2012 ?
Not sure if you ready answered it, did you have to do an aligment?
Yes
Not sure what year your ISF is but the USRS on my 2011 made zero improvement in steering feel or turn-in response. It did noticeably increase harshness over pavement cracks, expansion joints, etc. Could be that pre 2011 models benefited from this mod but Lexus made major upgrades to the suspension in 2011 so it may not be of any benefit on a 2011+. Could also be that if your original LCA bushing was shot, then replacing it with OEM might have also made a big improvement for you. Also, the USRS did not help my F with the infamous inner tire wear in the front. After only 12k miles, the Michelin PS4S are shaved down to nothing on the inside, and I don't even track the car.
My tech at Lexus fixed my inner tire wear for me. 9k miles on my front tires now and no signs of inner tire wear. I have the alignment sheet I can send to you if you want.
Could be mileage too, my car has 134k so the bushings had seen better days.
@@tcmcclure2323 thx yeah for sure, can u send me ur alignment sheet please.
mike indelak do you have an Instagram or email I can send it to
@@tcmcclure2323 can u email it to mike.indelak@gmail.com please. Thx!
Yes, zoom in .
Where do you get the bushings from?
rr-racing.com
Is it normal to have check engine light on after going fbo?
Tune removes cel
@@colby3333 yeah my uncle even use the tune to remove the cel and even went to lexus to fix the problem but then after driving 5mins away from the lexus dealership the cel came back on. He's guessing it's the Oil separator??
@@Honja999 I'm FBO and a&o separator no cel. What's the code from the reader?
@@colby3333 I forgot the code but I remember he saying it's like an 02 sensor and his car is just stuck in limp mode
@@Honja999 might have to replace that sensor
Right here....or just here🤔
Aussie IS F owners have been replacing them with RC F bushings.
I have them in my cart. I have a GS. Debating if I go stock or get the RCF bushings.
I installed RCF bushings about a month ago. I can't tell any difference whatsoever. I'm just hoping the toe-in issue is fixed once I replace the tires. That's what I'm looking forward to. It still has just as vague steering as it did before.
@@LordPrometheous Price is the same as stock. I wonder if it is a placebo effect. Right now with old bushings the steering feels like the control arms are held with exercise bands! They look cracked.
@@alb12345672 Now that I'm thinking back to the clublexus forums, I think they mentioned that the RCF ones don't FEEL any firmer, but they address toe-in. I've never been in a car with polyurethane bushings, so I've never been able to compare the feel of those to that of a stock car. I am interested to see what the difference truly is. I also have a Solara, and I have yet to replace the bushings on it (228K miles) and the steering feels the same. The car rides fairly smooth though, so I guess that might be why.
@@LordPrometheous Also I never hear of the tire problem with GS cars. Only the IS have the issue, and the platform is very similar. Maybe the geometry is very slightly different on those bushings (a few mm thicker?) I measured a set of stock ones and they were off by a few mm side to side-noticeable too (assuming the right parts were in the bag).
oh no i just spent 350dollars for labor in new Zealand just put it on my rcf
Kurt. Let me know when you're ready to sell your Lexus IS F
I'll post on YT when I'm ready to sell
Sell me your isf
It’s a Lexus which is a problem you cannot resolve!
