Hey Guys - I wanted to put this info in one place and help clear up any misconceptions about what size rotors and which calipers came on a stock SC300/SC400 based on model year. I also listed the information for the two most popular and cost effective brake upgrade platforms: The 1995 - 2000 Lexus LS400 and the 1993.5 - 1998 Toyota MKIV Supra TT. See the chart below:




A few notes:
1) All specs are USDM market cars. There are some differences in the JDM versions (Chaser/Soarer/Supra) if you want to try and get your hands on some of those pieces. "JDM, yo!"

2) Pre-1995 Lexus LS400 front calipers are not enough of an upgrade over any year stock SC300/SC400 to be worth considering so I didn't list them. Before you even ask... 1990-1992 are single pot with a ~275mm rotor and 1993-1994 are dual pot with a ~295mm rotor. Just use the ones from 1995-2000 which also have the benefit of being lightweight due to their aluminum construction.

3) NA Supra calipers are pretty much the same thing as your stock SC calipers; 2-pot with small rotors so they aren't listed as an upgrade either. Like the pre-1995 Lexus LS400 front calipers it's just not worth it.

4) TT Supra calipers will cost the most but you will have a HUGE selection of pads available for them. If you want to actually track your car on an auto-x or road course then pad selection should be a definite consideration when changing calipers.

Hope this helps some of you!

Nice work, and should answer lots of future questions.

Are the LS rear rotors really 0.1mm smaller than the SC's (I had thought they were identical calipers), or is that a double conversion error type of thing?

I pulled this info from multiple places so there is a probably a slight conversion error in there somewhere. Everything I've read said that they are interchangeable.

Sorry I don't understand the chart!

Which do the LS400's match up with? (specifically a 1992)

I'm pretty sure its the SC300 because I know for a fact the 11.641" front rotors DO NOT fit the LS400 (or at least mine)
