I haven't seen anyone compare them back to back. Both Abbott and
Taliaferro are very helpful. I would not hesitate to use the Talia
version for less $'s. DO you have a link to MP Performance ? I am not
familiar with them.

You might also consider a set of Koni adjustables. Try the rack brace
first and see how the car feels.

Mark,

You didn't mention if you had done anything else to firm up the front end.
You also did not mention how many miles you have on the suspension.
The improvement you will get with the rack clamp & brace is pretty subtle
and would likely only be noticed if everything else is tight.

I would consider this approach:

1) If the shocks and struts are original (and especially if they have more
than about 40k miles on them) replace them.  I have used Bilstein HDs and
many others recommend Konis.  You won't go wrong with either.

2) While doing the front struts, consider replacing the soft rubber bushings
at the rear of the stancion arm with urethane performance bushings.  This
will reduce the trendency for the wheel to move for and aft when hitting
bumps.

3) Before you start, check the condition of your balljoints and tie rod ends
for looseness.  Front balljoints are replaced by replacing the control arms
(which come with two new bushings and the balljoint). These could be easily
replaced during the front struts too.

4) If all the above parts and bushings are already in good shape (ie you
have very low mileage on the car or have recently replaced all of this
stuff) go ahead and try the clamp and brace.

Disclaimer:  I went through all of the above on a 2000 9-3SE Convertible and
when I was done I was still not happy with the suspension and steering
performance.  I ended up selling the car and buying something else that
better met my needs (desires really) for a tight handling convertible.
