So I've been driving it around with the new parts. First thing that struck me is that the ride is really not anymore harsh upfront than with the stock tension rods. In fact, I'd even say it's better with the pillowball rods. Handling is fab - the front end feels real solid, very responsive to input. You can really feel the limit of your tires in a hard turn now.
Also we put on a GReddy rear STB - that actually worked out much better than I anticipated, really firmed up the hatch area.
So was it worth it? Don't know so much about the Power Brace, that was kind of expensive, plain-looking (I'm vain) and feels pretty much just like a front STB, but the tension rods and rear STB were definitely worth it.
Time for some comp...
