The Pedders Cruze coilover are $400 less than the Sonic and there is a 10% plus free shipping sale going on. The Cruze part number is 10076 and the Sonic part number is 10076S. Furthermore, when I wanted coilovers for my Sonic Pedders said the Cruze coilovers would work with a work around, for the brake lines I think. I am impatient and did not want to wait for the Sonics and a work around for the brake lines scared the living daylights out of me so I got the Pedders lowering coils not the coilovers.
So my suggestion is contact Pedders, they are a forum sponsor, and ask and if the work around is something you can accept, go for it.
And yes, Pedders is the best.
