Need some suspension info pls (2nd gen)
I need help with some suspension info on the front suspension of a Gen2-2.5
LS400 (4 pot). Is anyone replacing their pads/rotor anytime soon i just need
some quick measurements using a caliper tool.... It doesn't have to be precies
just a rough numbers so i can work around with. Metric or Imperial doesn't
matter much i need these numbers to see if it's can fit in my car. Thanks in advance.
A = distance between mounting hole
C = diameter of spindle
D = distance between spindle and mounting hold 1
E = distance between spindle and mounting hold 2

did the supra n/a and turbo use different hub/knuckle? and can you use supra tt pads on the ls400 4pot?

I have no clue about the tt and NA measurements. The pads do not swap , tt has no slot for the brake sensor on the LS but they have the exact same pad surface size and shape just the metal backing plate is different .Also the LS ones have a second set of sliding pins on the ends.
Info on the rotors are 12.9 inches for the LS and TT are 13.1 .I think it was just a wrong measurement over it being different but so close.

Im abit of a newb in these part so bare my ignorance i got more questions 
Has anyone actually tried to use the tt pads? it's hard to see the brake sensor
on the supra pads, in my parts catalog but it appears to hang at the bottom of
the pads. why not just remove the ls400 sensor and stick with the one on the pads?
i also noticed the ls has bigger holes for the sliding pins. you should be
able to drill them. and this back plating, is that the shim kit? thats just to reduce the squeals
sorry to sound like a smart as, i've just been researching on brakes for awhile so im just blurting out what i know atm.

Are the rotor sizes you have from actual measurements or second hand info?
I got my specs from stoptechs catalogue. I have never measured them my self though .
If you look at the backing plate you can see that the edge next to the sliding pin is different so the notch on the corners do not match up as well the sliding pins are slightly bigger in size but the problem is they are not in the same positions either .
I had a set of project Mu pads compared to my aftermarket pads when i was installing them as i hoped the TT ones could be used for options but the caliper would not accept the differences in the backing plates.
The similarity comes from the mounting positions of the calipers and 4 pots and rotors.
