rotors so effn heavy
I'm on my way to the LS400 brake upgrade too. I bought the Napa Ultra Premium rotor (ppl reference: Raybestos Advanced Technology rotors) DID I SAY HEAVY? it's heavy!!
Bought the Adaptive one brake pads
And finally waiting for the calipers... one side is shipping from Seattle WA and one is Fresno CA remanufactured by ATM.
The one part that is holding my progress is the frickn bolt. I have the 3/4 inch custom block and need to find out the length of the bolt+ 3/4.Anyone know what the lenght of the bolt is? +3/4 inches offset?
Once I know the length, next quest is to find the bolts. I used to know a wearhouse that sells bolts...just have to cruise around to jog my memory. They have every bolts made on earth. LOL. btw, it's in Sacramento and near folsom and power inn area.
this scka is heavy!

Question: Did you guys use the ls400 bolts or the gs400 bolts?
edit: GSteg to the recue again! Thanks. btw, I'm painting my calipers blue. I wanted baby blue but can't find it - G2 paint. Baby blue and millenium silver is heaven; better than orgasm.

i was looking at upgrading my brakes... but the only question i have is, what did you guys end up doing with the rear brakes? did you guys upgrade to ls400 rear brakes, or left them stock?

Brakes
Still no answer on performance and feel??
Reading through all 9 pages:
Supra calipers are the world's gift to short stopping distances, have a 3/10" larger OD rotor than the LS400 setup, but are 1/2 alum & 1/2 iron.
LS400 are all alum. and "pretty" and should be better than the Supra units because they are newer and all aluminum and from a heavier car. A little far fetched, but what the hey, it could be an argument.
So the real question is this. Has anyone driven their buddies car with LS calipers and their own with Supra calipers or something like that, hopefully with similar pads, recent bleed, both on ss lines, etc.? I know that aligns planets, but surely...

Also short stopping distance with JZA80 calipers?
I thought the brake booster was the determinant of this.
GS braking distance isn't bad. and I think you're assuming way too many variables.

"lexus feel" = soft pedal
Sounds like you're on the way to answering this one. So is it a hydraulic mismatch with either of those calipers? Is the GS master just too large for the LS or Supra calipers?
Not bad sure, but they just eat through rotors. IIRC the 60-0 with these cars was respectable, but doing that on occasion vs. driving the car like a sports sedan on a regular basis and there is just isn't enough rotor mass there. Beyond that the calipers are heavy and retain more heat, at least compared to the LS caliper, so instead of just replacing the GS pads/rotors again I could spend another $200-$300 and do a Supra or LS swap instead.
Lets hear it

I don't think many people drive their gs hard enough to be asking questions about how the stopping distance is and how much better is it than the supra brakes etc its just not necessary for real world driving. I did them on my car for looks and performance, but only because I enjoy my car from time to time and I have used them on several occasions slowing down from 120. Imo they look better..perform better (no test numbers)..and are lighter than stock gs brakes. I am using lexus pads/rotors and ss brake lines with no complaints.

Yeah, kept searching, and no definitive answers, not a bad thing, if nobody knows then I'd rather not read a reply just because it felt good to type something, but I'm hoping someone can chime in with some objective info.

The brake booster on the 98-00 are smaller compared to the 01-05. I know for a fact some people in Japan have swapped out their 98-00 for 01-05 brake boosters and noticed better brake feel. No measurements or numbers are reported as far as I know.
I have the JZA80 calipers with Rotora rotors and Project mu pads and I can say for sure driving is more fun and a very cost effective mod. As for stopping distance, I don't know. Most likely a minimal change if any but the initial grab is nothing like the stock brakes.
Either way, we're using the same caliper as the IS300 which weighs how much more less than our GSs ?
