which springs to use ?

i've switched to 17" from stock and now i want to lower my car coz of too much wheel gap. i need your opinion on which brand of spring to use ex. Tein, Eibach, H&R,Tanabe,Neuspeed,Vogtland or Suspension Techniques

H&R, Eibach, Neuspeed, Tein are all good stuff. Get the best you can afford & dont try to be cheap using low quality parts.

Dont forget about shocks.

If you are on stock shocks.

Neuspeed soft sport
H&R OEM sport
Eibach Prokit.
