im at the point on my project car to start the suspension and i was wondering what opinions people had about the sphon coil over set ups for the front and back with QA1's and tubular a-arms. or should i go with eibach springs and a nice set of koni yellow adjustables? keep in mind that this is my daily driver and i wanna have the best suspension i can for the road and cornering BUT dont know if spending the time and money on a full coil over conversion would provide me with a dramatic increase of performance over the eibach's and koni yellows. what do you think guys?
