I have decded on ProComp shocks for price. Now I just need to decide which ones, and where to put them. Are Es3000's good all around, or are single 9000's better for the front. I have heard that two ES3000's in the front may be bad because they aren't designed to work in tandem. I'm ready to buy, just need the info. Thanks in advance. This is for a stock 90 K5. Also need to replace the steering stabilizer, ProComp too?
