Well I swapped the differential this week at Exact motorsports. The result is absolutely no more wheelspin. I have 245/40R18s and they stick like glue with the limited slip differential from the Supra TT. I did my best test today when it was raining. Even with wet roads I could not get wheelspin (Trac was off). I was grinning ear to ear. This will change when I am turboed but it gives me an idea of how well I will stick. The swapped diff feels like butter. Smooth as silk. I recommend this.

One thing is that I think it may skew the speedometer. Is this possible? When I drive at 65 on my speedometer I am flying by other traffic. I think with the change in gear ratios I am actually going around 73? Someone chime in here.

 

Wow. Sounds good. How much did the whole thing cost you? I am not sure about the speedo, hopefully someone will answer your question. I want to know too.

I got a great deal at $1175 parts and installation.

 

i saw a post one time about a box made for lexus/toyota ECUs that will correct the speedo for various things...

i think SC300T posted about it; its a yellow box or something

 

Sounds very tempting, would it work on stock rims and tires too?
You drove 65mph and fly by the traffic, maybe it is because it's raining and everyone else slow down?

 

most likely the gear ratio changed and you are going faster than the speedo is setup for (same thing happens when u put on larger rims).

sounds wicked man keep up updated on the turbo setup when u get it.
