i would not bother for now, i believe the suspension in my car is standard and for a daily driver it handles pretty dam good as it is, personally i would leave the handling, get the mods you mentioned done and go out for the next few weeks, in a month or so after the mods are done then decide if you want cooil overs or not, this will also give you more time to see what is out there and get better opionons on what people think of brands and coil overs in general, i have noticed a few ppl selling there coil overs lately and going back to standard because it is too stiff for a daily driver.
