Your SC300 auto has 4.27 gears to this LSD with 3.76. Your speedometer will read ~12% low as a result. It will read 53mph when you are actually going 60mph.

However, this can definitely be recalibrated. There are universal speedo recalibraters out there. Dakota Digital comes to mind. Their unit is like $75.

For traction, it is all worth it in my opinion.

 

where in socal are you?

 

near the beaches of OC

 

im in the san diego area..how far from there?

 

depending on what part of SD. SD is pretty huge. Anywhere from 1 - 2 hrs max

 

hmmm, well my car arrives here on the 18th of july. After that I'd prolly be able to come and pick it up if its not sold yet

 

The manual supra LSD is 3.13. This unit is only good for people putting in a 6-speed or even a th400. This unit is not good for a stock auto tranny or W58. If you put this in you also need a supra passenger side axle as it is wider then the auto unit.

 

He is selling an auto Supra TT Torsen LSD which is 3.76

It does fit in the 2nd gen GS, I would highly recommend this mod if you are NOT going FI - if you are FI you have a good chance of hitting the rev limiter with this unit.

 

Sorry my bad. Guess i pciked it up from further into the thread. All above is correct...my apologies.
