I don't think you'll have any problems using stock shocks with the prokits. Especially for the near-term when they're pretty new and in good shape already (I assume).
I'm debating between prokits and Tein coilovers....if I could get anybody to help me with my Tein thread....
I've known people to drop a lot more than prokits and use stock shocks without any issues over the course of 2 years. They could be the exceptions to the rule, so your mileage may vary.
