Depending upon the mileage on your car, before you have the kit installed, have someone take a look at all of your suspension parts.
Inspect your control arms, both upper and lowers, it is usually easier to replace these while you have the suspension apart. The new components will stress the older parts to failure in the near future if they are questionable. It's also a good idea to inspect or replace the steering linkage and tie rod ends at the same time. It's a little more expensive, but you will experience the full effect of how the handling and ride is supposed to be in these cars. Finally, the only other thing to consider replacing would be the upper strut mounts.
With all the parts replaced, your car will handle and ride like never before and you will enjoy it for a long time to come. It's more expensive, but you will avoid more labor later and will be able to have only one alignment done after all the parts are replaced at once.
Just my 2 cents worth,
