964 rear alignment problem

[rattlsnak]

I'm working on a project that has too much negative toe in on the right rear. Visually, everything looks ok. Aside from the body being twisted or such I'm looking to use an ERP spring plate which has a seperat adjustable toe setting. Anybody use these before? I want to know what kind of range it has. Since I have negative toe, I would think I need to shorten the arm, not lengthen it. here are some pics..

If you can't achieve the proper toe setting, then you have a bent trailing arm. The big aluminum one.

You can make up for it with the ERP springplate, but what it will do is alter the track slightly. You will actually have to lengthen the inner springplate to toe it in, so it will slightly widen the track compared to the other side. It will probably have an effect on the toe curve as well, and it's undesirable to have different toe curves left to right.

Thanks Tyson, i figured something was bent. I have too much negative toe now, so i assume i would have to lengthen the link as you say, but either way, looks like i need to get a trailing arm.. its not too far off, just a tad out of range which is why i was considering the spring plate.

Wow, that's one very clean underchassis and engine. Do you even drive that thing on the street?

LOL.. definetly not mine. I just the photo so you could see the spring plates..
