This was a slightly intimidating
process at first, but turned out to be well worth it. The car was
handling very poorly. I did not know why. To make things easier, I
ordered an adjustable strut rod kit from Street or Track, and a
Fastrack alignment tool from Summit. Along with those items a Baer
tracker bumpsteer kit. The installation was fairly easy. The set up
for the wheel alignment was easy.
It turns out the previous alignment shop had not
torqued the camber adjustment eccentrics properly. One was
completely loose (dangerous) and the other was hand tight.
So with that problem identified, I aligned the
car, and then undertook the bumpsteer correction. This involves
using a vertical laser and a straight edge on the wheel, with two
laser targets 40.5" apart. The spring and shocks are removed.
This allows free movement of the suspension.
The suspension is moved up and down in prescribed
increments. At each point the toe change is noted and recorded. The
toe change is measured by taking the difference in the target measurement
on the front and rear laser targets. Shims are added to the
bumpsteer kit and the process is repeated. This process took about
10 hours.
When completed the total toe change is less than
0.030" over the normal suspension movement.
