My slotted / drilled 95-00 LS400 rotor just came in. I weigh each and it came up to be 21 pounds.

I searched and found TT rotors weigh about 20 lbs each.

Do you know what you guys have?

 

The LS rotors that i have weighed 21.5# ea.
Mine are not slotted/drilled though.

 

Cool. Good to know

I thought 21 lbs is too heavy for a single rotor.

 

Do the LS400 Rotors have noticable cooling fins in the center or are they a solid disk?

 

they have the cooling fins on my stock LS400 rotors

 

Are not all rotors like that? Are they called "vented" as well?

 

"All" rotors vented ?, no. Re the LS rotors, I'm suprised that they they are reportedly heavier than Supra TT as LS are smaller and both rotors are vented.

 

me too, I thought the LS400 oem rotors were lighter than the supra TT ones since they're slightly smaller.

 

TT rotors are 17.5lbs

 

do they have any ls400 rotors that are just slotted?

 

i have the ATE rotors and i just slapped it on wen i did the LS Brakes but they are heavy

 

looking for oem part# on these rotor, anyone have them?

 

idk about rotors, but ls400 calipers are lighter then supra tt.
ls400 calipers are aluminum while supra tt are steel, or cast iron?

anyways. r1rotors or w/e from ebay will make rotors out of dirty metals and your actually better off, and even better performance with an oem rotor.

the dirty metals might posibbly be giving you that extra lb or so.
dont woute me on this info, but i do know the dirty metals, hence also the prone ability to being warped.

wow i just noticed this thread is 2yrs old. haha oh well, theres some info.

 

do u have the oem part number or spec/dimension?

 

dirty metal? I assume you mean pot metal, which is the the left overs?
