1992-1997 Sc400 brakes are .8" plus sized in radius and slightly thicker compared to 1992-1996 SC300s. Therotically the brakes should fit, but I'm not sure. The calpiers should fit fine(if you've ever installed brakes, al lthe way pushed back, there is quite a few inches of width between pads in even the smallest calipers, and the gap will adjust automatically thanks to the boot action and brake fluid pressure to compensate for wider or narrower[usually machined down or worn] rotors.) The only problem I can think of is that the Sc300s before the fog light era(the early 1992-1994 models) had 15 " stocker rim versus 16" for the SC400. If you have aftermarket rims, they will fit fine(same bolt pattern) but if you dont, they might just be too big diameter wise.

Of course you could play it safe and just get lexus or EBC oem replacements.

 

thank you for all the good information..=0)

 

I would say close to half the rotors on Ebay don't come with the center balancing extra holes...those are the extra drilled holes that sit right next to the lug nut holes...Those little extra holes are some what important to help reduce vibration... I would look for the ones with the extra holes......I made the mistake of buying Supra motors from China and they came with out the extra balancing holes and got a little high speed braking vibration...Had to re-sell....that was on an SC400 to Supra brake swap...

 

I'd get a price on oem rotors from your local AutoZone. Autozone prices are competive with eBay before adding shipping costs and some have a lifetime warranty.

 

if you really wanted to do a brake upgrade, i would suggest the ls400 brakes..its larger surface area would benefit in increased braking..give that a look

 

I have "EBAY ROTORS" for a 1996-2000 LS400 (i'm using ls400 pads, calipers, rotors).. Vented, slotted, drilled. I think the front pair was $80 or so.

They stop great, don't squeal, and look sweet too (slotted and drilled)

I'm using OEM sumitomo pads, if any1 is wondering. No complaints- and it's been about a year, or 15k miles

 

bought a set of brembo drilled and slotted off ebay. just came in today. Real test will be when i put them on 2morrow..

 

ppl on forums always tell me slotted and drilled is no good. I have them on my car and i think they stop great. Also they have yet to warp unlike my other rotors. The only negative i came across is after every car wash......it stops like ****....like water trapped in there or something. After a couple of hard stops, it returns to normal.

 

dont buy drilled rotors, especially off egay. i bought my car and they came on the car, now they are cracked at each drilled slot and warped so i have to buy new up front, but im planning on upgrading so it's just a reason for a larger brake system.

 

Aren't the supra tt rotors larger too? How big are upgraded supra rotors anyway?

 

just paint the rusted centers of ur rotors with high temp paint...thats if u just wanna replace ur rotors for looks. i painted mines gloss black.

 

It would seem a few people here would benefit from reading Pulp Friction and Gimme a Brake.

Rotors with holes crack before rotors without holes. Discussions about pad outgassing refer to brake pads from the 80s, not modern brake pad materials. Holes are pretty on street cars and have no place in racing unless you can afford to throw out your rotors every weekend, AND you have a desperate need to minimize unsprung weight like ALMS.

Supra rotors are cheap even from Toyota. I paid $65 each for my fronts. With Hawk HPS pads, I've gone over 60k miles and I still have 50% left. The OEM pads ate the rotors and I threw out both rotors and pads at 63k because both were at service limits.

Also, Supra rotors are 310mm in the front, and they're directional. Few if any replacement rotors have the curved vanes of the OEM rotors.

 

Do you have any idea why the 94 Sc400 Front Rotors are $46.00 each while the 94 Sc300 front rotors are $109 each?

 

<--------Strongly dislikes the use of After-market parts. OEM cant be beat quality wise. Anything less, problems won't arise all the time, but be prepared

 

i have the oem rotors from ebay from autosquare and some auto zone pads and there good for normal or sport driving but if u plan to be driving like a menace just buy a big brake kit
