Coilovers are good for once in a while use. For like car shows.
People DO use them for daily drive but I dont like it the same why I dont like cutting springs.
its better you get *progressive* lowering springs, if you want to maintain a somwhat smooth ride. The *sports* lowering springs are right out HARD. Your balls is get damaged whenever you hit a pothole
Of course you can always just get soft lowering springs if all you want to do is rice out
Dont go more than a 1 1/2" drop. You can safely cut a coil from those springs IF you want a lower ride.
you can get them from as low as $800 for the soft lowering.
sports from $900-1200
progressive from $1500-1700
the Ralliart is round $1500-$2200 depending on the ride height and how hard you want it.
this is from my head eh so dont kill me if the numbers are a bit off
