^ +100. By all means finish the suspension. To be brutally honest I don't see this as a legitimate question. You have 80% of the parts already on hand to have a stellar suspension setup less the struts/shocks. You'll be kicking yourself down the road if you perform/pay for all the labor to get those lowering springs in only to find out the car is pathetically underdamped. A well setup suspension is different than literally all other mods, being that it is constantly at play whether you're accelerating, braking, in a corner, cruising, etc.
That said. If you're not ready to put the suspension in yet gears and a tune= lots of smiles.
