Whats the purpose for the upgrade going to be? Autocrossing or just for ride quality/looks?
If youre looking to get a good autocrossing setup Id suggest you look into whether or not H&R/Apex offer custom spring rates.

Another thing youll want to find out is what type of adjustability do the shocks have? Rebound? Compression? Neither?

I still say save your pennies and get a custom made set by TrueChoice. You can pick up a stage three set for just a little over 1400 or so. Maybe even less than that. Rebuilt Koni shock with dual adjustability shortened rod custom springs blah blah blah...
