I am having a delema of decidign which springs to go with, at this point I am leaning towards the Teins. I also am riding on stock shocks..

Thanks In advance

 

Tiens are the softest of the three. They will drop your car, but you won't find much of a difference in cornering. The Neuspeeds aren't really high quality springs. I'd go with the sportlines if you are going to drop 2+ inches.
