I thought I would bring this thread back for a little update.
Miles on the car at the time ofthe orginal posts was about 60K.
The first thing I did was to get the alignment checked to get a baseline - it was all over the place, way out of spec. I'm sorry I don't the numbers handy but the rear camber/toe was out as well as right side front. Front right could not be adjusted, needing an adjustable ball joint. One of my mistaken assumptions was that the front settings were ok, this was not the case.
Tires were shot as well, so I wanted to ensure that I had proper alignment to avoid tearing up a new set of tires.
Next step was to install the SPC rear camber kit and an adjustable (MOOG) ball joint in the front. Alignment was eyeballed at re-assembly. The SPC kit went on very easily, decent quality.
New set of tires went on, I chose Yokohama YK580 from Discount Tire.
Back to the alignment shop - alignment was able to be put back into factory settings with the adjustable rear camber kit and the new ball joint, plus toe, etc was set. I don't have those numbers handy either but I do remember that some negative rear camber was retained, I think it was around 1 degree.
Off I went into the sunset. As you would expect with new tires and proper alignment the car was a pleasure to drive. I did keep a close watch on the new tires to see if there were any signs of scrubbing or cupping. I just had the tires rotated at 67K miles and the wear is almost non-existent, no evidence of any of the issues I was encountering before.
At this point I'm pleased with the overall results, well worth the additional effort and cost. The only downside is that now I'm way too aware of how many cars out there are going down the road with almost a pyramid look from those back tires
