EIBACH PRO KIT V.S. SPORTLINE SPRINGS

Well I just bought new 18x9 rims with 265/35/18 tires. I also have a cervini type 2 chin spoiler on the car. My question to all of you if you were in my situation what springs would you pick. I want to drop the car to get the best look but i dont want to have problems with it. My biggest fear is i drive over a curve and there goes my chin spoiler that i spent my hard earn coin on. So fellow mustang nuts, give me your two cents. If you guys have gone with one of the two i would also love to see yalls pics to.

Ps. Plase dont tell me to go with some really high cost system. My broke ass is on a budget so im looking for somthing in this price range.  

I bought the handling pack from FRPP.  It is actually made by Eibach and has the same specs as their Pro-Kit. In fact my installation directions kept reffering ot the Eibach parts.  Carrol Shelby uses the same setup on the GT's that he is converting.  It rides stiffer, as expected, but the handling is much improved.  I rented one of the Shelby GT-H Mustangs from Hertz and drove it for a day to see if I could live with the ride qualities.  I ordered the setup immediately.  The drop is about 1-1/2", plenty for a car that is already sort of low.  The sportline kit will get you another 1/2".  You can save a good bit of money by only purchasing the springs.  I think they would work fine with the stock dampers and antiroll bars.
