Lexus Upper Control Arm Replacement With Adjustable RR Racing Billet UCA for Camber

[@Parakoopawing]

Thanks for this video in particular Barry. It helped a lot! I needed a ball joint puller to uninstall the old control arms.

Welcome back fam 👏🏾

[@thehuangbros]

Ayee how you been brother!

[@lancercool1992]

Oh my gawd THAT’S HOW YOU ADJUST IT? My local shop is going to hate me, RR Racing should have a chart of how much thread exposed = how much camber

[@advantist]

The stock RC F is supposed to have roughly -0.5 degrees of camber in the front, with about -1.5 in the rear, according to TIS. And, as for rear control arms, those may be a good idea also. I have found that about -1.8 rear is about perfect in terms of wear and grip. -2.5 for the front is plenty enough.

[@thehuangbros]

Im currently -2.5 up front and -2 on back right and -2.4 on back left. I have some adjusting to do

[@olivermurray6804]

Cool video m8

[@thehuangbros]

Hope this helps you.

[@scorpio_9810]

I have the Truhart iteration. They aren't exactly easy to adjust when the weight of the car is sitting on them. These appear to have a more practical design, so I might consider grabbing the kit.

[@thehuangbros]

The only way to adjust these are to remove the rear solid mounts and twist. So these, figs, t-demand, etc are all tedious and time consuming. 🤷🏻‍♂️

[@scorpio_9810]

@@thehuangbros thanks for the feedback. On second thought these ones appear more difficult to adjust. The increased positive caster is still desirable, though.

[@aaronwilliams6165]

Car looks great underneath! I love suspension and being able to harness the power will make the drive a better experience and faster. Can't wait for the rear camber arms! I've got to get started on my RC350, just broke 20k miles and I needed more power. Great video!

[@thehuangbros]

I already have my rear camber arms in but I am likely going to take them off and put them back on to make adjustments easier

[@colby3333]

@@thehuangbros what rear camber arms are you using?

[@thehuangbros]

@@colby3333 i have SPC but will be switching to Figs.

Very nice work like always thank you for showing us 🙌🏽🔥🔥🔥🔥🔥

[@pecks33331]

Good video. More please.

[@Simple5.0]

I wish those upper control arms were adjustable in place. I mean I know you’ll probably set it and forget it but having that extra bit of adjustability would be awesome. You could really dial in your camber for the ring. You’ll never take that apart just to see what 2 spins in or out would do. They’re a nice looking part though and I’d bet they feel good on track so…

[@thehuangbros]

Im running into that issue now. I cant just freely adjust but now I need to have less camber. Im at -2.3 up front but want -2.0. Now i have to keep removing and adjusting.

[@Simple5.0]

@@thehuangbros it’s impossible to think of everything. I had to learn that one the hard way too. No biggie. You’ll know for next time and for more parts now. Even when it’s more money always go with the one that you can adjust when it’s in place.

[@MattTheClutch]

Any noise from the top arms to this day? Mine make a slight click and crunch when turning fully.. but they do their job rly well! But slight click when jiggling them also when tire is off.. thanks man great vid

[@thehuangbros]

Mine has not. Any rust or dirt around the joints?

[@phothrottle]

Looks so nice!

[@dvaritek2841]

What is this telepathy, I was just about to ask if you knew or thought about a camber kit for the f. Great vid thanks for the f content.

[@thehuangbros]

Hahaha I also have rear camber arms. Going to make a video for that too.

[@JohnSmith-kl8hu]

Nice vid. About to install exact setup. So if I want -2⁰ all around what specs/measurements (1 3/8in for fronts?) should I have to avoid going back and forth with alignment guy? Ty

[@thehuangbros]

Well thats the thing, you wont know until you have a camber mesaurement tool to let you know where youre at. How low you set your coilovers also determines that too. Im currently -2.3/-2.4 up front .

[@Magicstockton]

Yeah man I’m looking at these that $600 tag is making me hesitant. But I’m hearing a clunk on my front drivers side (not the ball joint, not the end links) my car is lowered on stock upper arms, I did notice the bolt was bent.

[@thehuangbros]

Could be many things for the clunk. Could be too low or the tire/wheel combo is too big

[@bilalsiddiqui3329]

Looking good! What’s your review now after many months of use? How much caster gain is possible with the offset? 20’? 0.5 degree? 1 degree?

[@thehuangbros]

it gave positive caster for sure. I would say a good 0.5 deg. Id have to check my alignment sheet printout. So far it has been really good.

[@clappern7413]

.5 degree caster

[@nomuscleasianman]

Great vid barry. Are you running 4inch length helper springs btw

[@thehuangbros]

2.36in swift helper springs. 1.5kg.

[@Rogue-Sentinel]

Only thing missing from your RCF is lower miles so you could Supercharge It!

[@thehuangbros]

Haha If I have a low mileage RC F, I would not be making videos. I would not waste money on a car I don’t even drive. It would be very much stockish. 😂

[@dvaritek2841]

The 2ur-gse is bullet proof. He could def supercharge it from that perspective. Transmission is also pretty strong. The main thing that might have an issue at high mileage boosted might be the tvd, but I'm not sure about that. In theory if you keep clean fluids in that should be fine too.

[@thehuangbros]

@@dvaritek2841 that is what I believe too

[@jeaand247]

U make it look EZ

[@thehuangbros]

The hardest part is the ball joint removal. Overall only few bolts to remove 👍🏼

[@scorpio_9810]

That's coz it's in fact an easy DIY.

[@thehuangbros]

@@scorpio_9810 very much so.

[@endason]

dope thx for the info!

[@thehuangbros]

Hope this helps when you need it

[@davidtranmedia5112]

Keep it up. 1st

[@thehuangbros]

Thanks man. How is the IS of yours?

[@allboutthemojo]

@@thehuangbros can you recommend a specific mod for the IS 350 f sport to improve the sound? I don't know what upgrade I need to do. Not interested in that annoying sound where you can hear the car acceleration from a mile away, just looking for a nice rumble ( heavy but not loud) . Also without too many mods. Thanks

[@thehuangbros]

@@allboutthemojo just like me. Not too loud but just want to know the sound is there. Im not too sure of a good exhaust for IS350. No one really ever walks up to me and shows me their IS350 haha

[@allboutthemojo]

@@thehuangbros LOL. Yes ofcourse the IS 350 does not compare to the RCF because it's a sport sedan vs a sports coupe . So I just have to replace the muffler? That's all?

[@thehuangbros]

@@allboutthemojo yeah just the catback exhaust is good. Once you change headers, itll give it a raspier pitch. So far that is what Ive noticed from the V6 engine installs.

[@Simple5.0]

You haven’t by chance driven an m4 too have you? I’m stuck deciding on what to get next. I want an m4 or an rc f. I’m kinda stuck though. Any thoughts?

[@thehuangbros]

Never

[@besc0bar]

this isn’t available for the awd version, is it worth to still get the coilovers and usrs unit with this part stock?

[@thehuangbros]

Yup. This part isnt really needed unless you want good camber for track. The stock one is good for daily driving and spirited driving.

[@besc0bar]

@@thehuangbros I got just the usrs unit for now to see what difference it makes. I don't have any interest in lowering the car, just improving the steering response for commuting

[@thehuangbros]

@@besc0bar the USRS will do it. Any upgraded bushing in that area is good

[@RubberChickenMan007]

How much of an impact has this had on handling?

[@thehuangbros]

Its been excellent for the track. Less Understeer.

[@RubberChickenMan007]

@@thehuangbros sweet, I'll get them. Are they have the same setting you had in the video?

[@thehuangbros]

@@RubberChickenMan007 no you have to set them to it. It also depends on your coilover height too

[@RubberChickenMan007]

@@thehuangbros how do I determine what I need to set them to? Actually, I'll reach out to rr racing and see what they recommend. I ordered the Penske shocks last night and I'm hoping they can set ride height and control arm length before it's sent out.

[@thehuangbros]

@@RubberChickenMan007 there isnt a magic formula. You just have to play with the settings. What they can get you to is something relatively close to each other. But once you install is when you tweak it

Need to align

Yes you do
