Well Guys, I have been working on cleaning up the TT subframe assembly to prepare it for the install. While doing this I have been doing a side by side comparison of the TT subframe verses the Stock SC. First off I Would like to say, Those who say there is no gain in swapping the entire unit are wrong. Here are some of the differences I have noted.
Both the front and rear Lower Suspension links are are about 3" shorter
This was done for a couple reasons I suspect. Shorter links mean less flex and better control for cornering and drive trane shock from a manual tranny. They could shorten these since the Supra didnt need the extra travel due to it being lower than a stock SC I think. Stronger!
All four Body mount rubber bushing are a much stiffer Durometer along with being heavier built.
This again will serve as a much harder launch with a manual tranny. It is very clear this was intended for abuse! This is a Big Deal
Diff mounts are also stiffer rubber
Same as above
The actual subframe has subtle differences in construction.
These changes reinforce the frame for added drive Trane shock. Things like more boxed in arm mounts, More stamp reinenforcment in areas that count.
Of course don’t for get the Sway bar.
Tying the sway bar to the actual subframe instead of the body is for business type cornering.
And TT brakes to boot!
At this point I am pleased that I chose to swap the entire subframe assembly.

Here is a comparison between the lower rear arms.
Top pic is TT subframe, lower pic is SC400
Pic a spot on the subframe to campare like the rear mount or top Arm bolt to really see the difference.

I swapped the E-brake cables, It went really smooth. Just had to swap one mounting bracket (Circled) from cable to cable.

Sanded all the rust off treated it and shot it with wrinkle paint. The rear end is ready to go back in the car in the morning.
