I would keep saving your money and just do a coilover setup. After you pay for the springs and someone to install them your most likely going to want to go lower, which would be a waste of money.
Also, I bought a pair of 2.25" zenn lowering springs off ebay(waste of money) by the 2nd day they were on I had 2 blown shocks in the front. Now, a pro-kit will be 100% better then ebay springs but they might not lower your car as much as you want. Good luck with it!
