LOL. You've got me there as I pieced mine as well, after deciding to keep the standard ride height due to my driveway and some of the roads I encounter. In the OP's case, with a car modified by someone else without the specs on what is there, it seemed good advice (though not essential) to start with all the pieces spec'd to the ride height desired. So, it seems either way is "the" way to go depending on the amount of time and thought one wishes to expend on picking the pieces. I liked Beechkid's thoughtful rundown on struts/shocks...I have both Bilstein and Konis on vehicles here, but no doubt other brands would have performed as well under the conditions I impose.
In my case, even with the stock motor, the pieces described over this series of posts settled the car substantially in the twisties...virtually eliminating the feeling of it trying to go another direction than where pointed or break loose. ((MM HD RLCA Poly/Spherical and Ford UCA rubber, btw)). Keep smiling.
