BIG Brakes on my LEXUS! (LS400 brakes on GS400)

This guy has been instrumental in giving confidence on working on my GS400. His videos are great and I have the same color gs400 year 99

[@MushroomFleet]

I started following you around a year ago as i had purchased a 2004 GS300 and was looking for other owners to learn some tips. Your channel has been more than informative and you have given me much needed direction and suggestions when planning my Lexus restomod project. I wanted to give an update on how my project had gone so far, it has been worth EVERY PENNY ! Thanks again and keep the videos coming Boss!! I picked up my JZS160 GS300 (2nd Gen) for £800 in May 2020. I was told it would fail the safety test on ABS, VSC, Exhaust Leaks and Engine Lights from dead 02 sensors. I worked for Lexus as a service collection driver in the early 2000's when these cars were brand new. The GS needed a lot of work done as the previous owner seemed to have only done minimal maintenance. One Spring had fallen through the Damper Stops and was resting on the wishbone! I won't lie, even with connections to the motor trade and a fully trained toyota mechanic for a brother it still cost me *A LOT* to get all the work done, but i went beyond what was required and now the Car is Solid! OEM Spec & New parts fitted: All 4 suspension Dampers & all 4 Springs, Full Exhaust System, All 02 Sensors, ABS & Speed sensor, front wishbones on both sides, upper control arms on both sides, New Brake Discs & pads all 4 corners, New Wheels & Tires all 4 corners, full engine service (new plugs, rocker cover gasket, all fluids, all filters) All in we are £4500 deep. Some say that was too much, but I never had all that money at once and had to pay in parts over time. My argument was simple, if i bought a lower mileage example for around £3500 (the market price) I would still have to replace the exhaust, brakes, suspension parts in both cases. Worth it.

[@ForwardMomentum]

Wow! Awesome update. Well done on your GS! Glad my vids could help a little. I’ll be doing a manual swap next. It’s about to get real! 😎

Just some advice for copper washers, Advanced Auto has a kit that comes with a variety of copper washers. If you got a 2jz-ge or 2nd gen gs300 there's a size that also fits for the VVT-i oil tube.

[@ForwardMomentum]

No, not in the front. In the rear I run 25mm spacers.

[@bruno90063]

You think a 17" wheel would fit no spacers 5 spoke? Platinum Edition

[@ForwardMomentum]

No idea. It depends on so many things like offset, wheel design, etc.

[@roedolphlouw7774]

What spacer did you talk about at the beging of the Video? the one at the lower ball joint? Did you make it or can you buy it from somewhere? LOVE your car and all the mods you have done over the years.

Hi - thanks! It’s an 18mm roll center adjuster. I got it years ago from SAGE. Not sure he still sells them. There are other options out there. 👍

[@kasinong2413]

Do you use the original caliper bracket bolts? or the ones that come with the LS400 calipers? Thanks!

[@ForwardMomentum]

I’m sorry, I did it so long ago I cannot remember. My friend sent me everything so I didn’t pay as much attention as if I pieced it together on my own. When you get the LS calipers grab the bolts to be safe if you can.

@@ForwardMomentum thanks brotha

[@PanZapalka]

Hi, question regarding roll center adjusters: I understand the overall idea behind them, but there is something that bothers me & I haven't found any speciffic answer to my doubt's on any forum. Don't they affect suspension's geometry somehow? Don't they add ride hight? When doing realingment procedure will i need to make some corrections with these spacers installed? Greetings from Poland ;)

[@ForwardMomentum]

Hello! They do effect geometry, yes. They add positive camber and they actually lower the car the same thickness they happen to be. So if you lower the car and camber goes negative, it can be corrected a certain amount. That’s the simple version. There are more detailed explanations online as there are other small effects. Greetings from the USA!

[@braunstrollmen314]

For the brake pads? What brake pads did you use? Do all ls400 of that year use the same front brakes?

[@ForwardMomentum]

The brake kit and pads were given to me and my friend wasn’t sure what year they came from. That’s why I didn’t include the info in the video.

[@sanjosonny2503]

Love it Wanna do this on my 01 gs430 16s won't fit, but the stock wheels on my 01gs 430 are 17 inch Think they will fit?

[@ForwardMomentum]

You’ll most likely need a 20-25mm wheel spacer in addition to a 17mm+ RCA. Just depends on wheel design and offset.

[@sanjosonny2503]

@@ForwardMomentum ok Cool appreciate it

[@spickert34041]

Another great video for GS owners... where was that 16" wheel making contact, on the face of the caliper? Would a spacer help it fit?

[@ForwardMomentum]

Thanks. Yeah, but the spacer would have to be pretty big. I wonder how the 16’s on some LS’s fit? Hmmm

[@jdm_donny]

@@ForwardMomentum it depends on the offset! Usually with the 95-00 ls400 caliper upgrade, you need about +45mm offset. At least that’s how it is for us 90-94 ls400 guys. This is one of my favorite upgrades and always recommend it for people who want nice brakes for cheap. Nice vid and awesome car! 👌

[@Arnas.Spark.]

@@jdm_donny Maybe you know how mutch more do these calipers stick out than stock GS or LS 90-94 calipers, I'd love to upgrade, but I already have nice aftermarket wheels so I wonder if these calipers would fit. Now the gap between stock caliper and spokes around 10mm, I know that in theory I could use spacers but my 8J rims sit very close to the fender arch

[@TubularTurtle]

Did the RCAs drop your height any? My GS430 is on coilovers and I don't want it much lower, if it all really. Want to know if I'm gonna have to readjust my coilovers.

[@ForwardMomentum]

Yes. It drops the car as much as the RCA thickness is.

[@1995RangeRover]

Looking good bro!!

[@ADAYWITHJMS]

So quick question. I normally see people using roads when upgrading to bigger breaks and I noticed you didn't use it and it looks like it's no issues. So do I need rca's or not? Lol. I'll be running 95 ls400 breaks

[@ForwardMomentum]

Possible dust shield contacting rotor.

[@nicwithags6182]

Just to clarify the gs doesn’t need the offset spacers/adapters to bolt the calipers on the the spindle like the is300? I wasnt sure if they were direct bolt on like the sc300/400s?

[@ForwardMomentum]

Calipers on spindles is direct bolt on as shown in the vid for the GS.

What size is your rims will stock 17 work

Bolt pattern is the same. However, diameter will need some research. I’m seeing conflicting measurements online in regards to diameter and some sites list them as the same. I don’t have a definitive answer for you.

@@ForwardMomentum Could you possibly share what RCA's you have? Also I'm pretty sure that the LS400 calipers are from a 1995-2000 LS400 but maybe share that info with people because they might be confused and get the newer calipers from 2001 and up?

@@JL-kz2ts I have Sage 18mm RCAs. Since production of the LS400 ceased in 2000 (chassis code XF20, I figured it was fairly clear which brakes I had.

Will LS430 front and rear calipers fit?

[@ForwardMomentum]

I’m not sure. Sorry.

[@kariu.]

do you need RCA’s for the rear too? or just the front?

[@ForwardMomentum]

Rear brake caliper upgrades are rarely ever big enough to warrant anything like what I show in this vid for the fronts.

[@kariu.]

oh for real? because i planned on putting ls400 calipers for fronts and rears on my 2gs. i just wanted to see if ill need RCA’s for front and the rear, but should i even touch the back? or leave it with the stock rear calipers?

[@kariu.]

@ another thing is, i don’t know if you know what “350z HR 18in wheels” are or how they look like, but if you can look them up (they’re big 5 spokes) and maybe let me know if they’ll be able to fit along with the LS400 calipers/rotors i’ll greatly appreciate it

[@ForwardMomentum]

You’ll lose your e-brake if you put front brakes on the rear, plus the bracket sizing is different. The rears have very low duty, so people just upgrade them for looks. You can go to LS430 rears with the right conversion brackets. XAT Racing also has rear BBKs. Not sure about those wheels, sorry!

[@kariu.]

@ losing the e brake is kinda crazy😂. but yeah maybe just the fronts for now then😂

[@InverseGrill]

Can I reuse the gs caliper bolts or do I need longer ones

[@ForwardMomentum]

I reused mine, but please double check that it’s what others do. What matters is fastener grip length, so measuring the thickness of the OEM caliper vs the LS should give you the answer.

[@ssjdavid]

You left your rear brakes stock?

[@ForwardMomentum]

Correct.

[@ToffeePeanuts]

Can you remove the dust cover with the hub still in? I'm planning on doing this swap at the same time as I rebuild and paint all my suspension
