My rear tie bars (rear rear control arms, or rear lower control arms, NOT trailing arms) are aftermarket, and at my shop I cannot get the rear toe to come in far enough. The toe adjuster slide is maxed out, and before I go big bucks to replace with factory, I want to know if there's any difference in overall length between the two. If the stock bars are longer, than it will help bring my toe in. The car had a lowering kit, so maybe that's why the shorter 'red' bars were used? I've actually drilled the adjuster slides too and widened them slightly which helped a lot but still not perfect. I'd rather not spend big bucks on a toe adjust kit. Thanks

 

Define aftermarket. What brands are we talking about?

 

I have no idea because they were on the car when I bought it. They look like this

 

How low is it? Is there a camber kit installed? Maybe you can try the old washer trick.
