I have done my search and I didnt find an answer to my specific question so please help me.

I have 19x9.5(F) and 19x10.5(R) Volks GT-7s. As you can see from the pic, I desperately need to lower my car. I have read from others that Tein S.Tech springs only lowers .7 inch in the back and I dont think thats enough for me to hide my gap. Would Eiback do the trick ? I am afraid that its gonna rub if I drop too much...

Is alignment a must and if so how much does it cost to get it done ? Thanks

 

The Eibachs should give you more drop. Here's a pic of mine dropped with Eibachs and 18" wheels.

Any time you change the suspension geometry you need to get an alignment unless you want to wear out tires alot.
