I don't have first hand experience, but I'm pretty sure there is a difference in length between the usdm GT, and GT4 trailing arms. Either that, or the mounting point for the trailing arms is different between the two frames. A member recently posted their GT4 conversion showing that they had to lengthen the arms to get the wheel in the center, I'll post a link if I find it

First, the rear is too high, get it lowered at the right height, it will move the wheel a little back.

Yeah, but they used the whole floor pan whereas Malek's old car just had brackets welded on, I believe?
You would think everything should line up almost perfect by swapping out the rear floor pans, but obviously there is still something else that we're missing since the wheels are being pulled too far forward.

I'm gonna measure the st204 and 205 trailing arms this weekend to be sure

I can take measurements as well if need be

I'd say start with measuring from the center of the big hole on each strut tower to the latch. Doing that on both sides. It's the most simple thing to measure.

One from a GT4 and one from a swapped one.

Here is some pics at different height, see how it gets forward when it's higher. The "standard" height you see here is a little higher because of the stripped interior. Anyway, it's just to show my point.

Domspun you may be right . The ride height would definitely force the wheel to follow the arc created by the trailing arm. I wonder what would cause that difference in height? I dont think the stut towers are different height between the two chassis.... In any case others have worked around this issue by modifying the trailing arms. Scroll down and you'll see that the rear trailing arm was modified to allow for adjustment.

So what you're saying is slam it and the wheel should be perfectly centered laugh.gif

That does make sense though. Since the car is sitting higher, the trailing arm would be angled downward thus pulling the wheel toward the front of the car. As the car is lowered, the trailing arm becomes more level thus pushing the wheel backward and making it more centered in the wheel well.

The GT arms are half an inch longer. Im going to put them in the trunk. When Nick puts coil overs in and lowers the car he can decide if he wants to swap them out or use both arms to make one. I can see how the increase in ride hight would cause this issue. I too do not know why it sits up so high. He plans on getting coil overs as soon as its down his way.

So Nick flew in last week and took the car. I suppose this will be the end of this thread. Took it to the local toyota dealer had the car aligned. Toe was spot on all 4 wheels. Caster and camber where off slightly but there is no adjustment from the factory. Had only one small hickupp on the car after completion. When i was driving the car home from the dealership the alternator failed leaving me stranded on the side of the road the day Nick was boarding his flight to come get the car. But after i replaced the alternator everything was great. He drove it from Fort Edward NY to Base in North Carolina with out issue.

Dont forget to check out my facebook page for future projects link in first post. Currently in the garage is my 93 st185. Plan is 2grfe swap, Borg Warner EFR, AEM Infinity 6, sunroof removal with non sunroof skin, and weight reduction. End goal is 500 awhp and 2500# street car and apear to have a full interior.

In between 1uzfe swap in my ae86 and 6speed trans install in my 2zzge aw11.
