Stopping Power: Supra vs LS caliper

Stopping Power: Supra vs LS caliper
Supra is a two piece calier, but from a Supra.
LS has a bigger diameter rotor IIRC and aluminum monoblock (I would love to have less unsprung mass) but a PITA to install.
Does anyone have actual first hand experience of the difference of stopping power? It's one of the things I want to do this summer and was wondering which one has better stopping power; initial stopping, fading, etc. I drive my GS mainly on the streets.

Supra rotors are at 12.7"
LS400 rotors are at 12.4"
Go for the supra if you dont want to run RCAs. Though if you have coilovers, it might be to your advantage to have those RCAs. Other than that, The install for the Supra and LS400 setup are the same.
As far as stopping power, they're about the same within city limits. Even on highway, the LS400s have no problem stopping the car. Fade advantage goes to the supra thanks to the larger rotors and bigger pads. Plus the Supra setup has a lot more aftermarket support for pads. In the end, it's up to you if you rather have less unsprung weight, or bigger rotor/pads. Mind you i've driven one GS with the supra and two GS with the LS400s.
I myself will have the LS400 calipers because I probably wont be able to take advantage of the Supra's larger rotors/pads. Plus, I already have 4 pairs, yes 4 pairs of LS400 calipers . I started to collect them awhile ago.

huh, I guess I was wrong about the diameter. thanks for the input! i love your posts b/c it's based on facts.
I'd love to get RCAs since I want to keep my ride height but i want to gain back some suspension travel but i can't justify myself 300bucks for an block of metal...
I probably won't be able to take advantage of the JZA80 calipers so I'll probably get the aluminum ones to take advantage of the weight. And I'll probably shave the bolt since it seems like it's above the cotter pin.

Yes, just shaving off the bolt is good enough. I've shaved it off someone else's car before and the cotter pin still fits. Just cut carefully. Measure twice, cut one
I think Exact motorsport sells RCAs for a bit under $200. But none the less, shaving off the tie-rod bolt is okay.

How much are you dropped right now? I say just shave off the bolt and throw those LS400s on. You can always do RCAs and an alignment later on when money permits. Even if you go with the Supra setup, you'll still be paying at least $150-200 more, and you're suspension travel and camber will still be the same.
I dont know what the going rate for the Supra setup is, but the LS400 setup will cost around $450 (without RCA).

I'd say go with the TT calipers. Just because of pad selection. It all really depends how you drive as the previous poster has mentioned.
Personally, I've managed to fade my big brakes and according to my friend they were glowing red too lol. Honestly I think I'm the only person on this forum that can seriously say a Rotora 4pot 14" on all 4 wheels BBK isn't enough
I'm planning to upgrade to the 8 piston 15" brakes soon. 14" bbk is unsafe at these power levels

I was actually considering that as well. Know where to find them? The 8 pot BBK costs around $3500 already, so I don't mind paying more for the carbon brakes.
EDIT: I just checked on those carbon ceramic brakes. Seems like only place I can find it is off a wrecked 997 911 turbo porsche. Looks like that's not a viable solution since I don't want to CNC new brackets. Well, I'm too lazy to lol.

I had the Supra TT brakes on my GS300 and it would stop just fine on the streets. No fade and no problems whatsoever. I also tested them out when I first installed them and the car would nose dive when I slammed on the brakes at 40mph. I was even able to get the wheels to lock up at one point on my 19" Blitz Z3's.
I have since then removed them and can feel the difference in the car, but I plan on selling my GS soon anyways.
So my vote goes to the Supra TT brakes.

Jeff, if your stoptechs are not doing jack to slow you down. Let me know if you're interested in the D2 Racing BBK that I have. I say 12 pot in the front with 380mm rotors and 8 pot rears with 356mm should slow a freight train down real quick. But it does hurt your head though if you decelerate really fast....

jeff, you're nuts, 14" brakes...i think my old Avalon had 14" wheels lol.
Thanks for the supra caliper input guys. i wish i could get them since theyre easier to install but im leaning towards the aluminum monoblock LS ones since i just drive my GS on the streets and don't need that aggressive pads.

just adding to this.. i found ls430 calipers new for pretty cheap.. but i already have ls400 calipers.. anyone try ls430s? prolly wouldnt make a difference.
go ls400+ss lines and call it a day .
supra calipers cost alot of money for no reason..
trd calipers (found on TRD and TTE edition aristos and gs300/400s go for eveŽn more money.. they bolt up just like supra calipers)
