I though its good to create a topic for Aveo coil-overs.
I installed a set of coilovers into my ride. Its 32 steps adjustable for shock hardness or softness. Its ride height adjustable and spring preload adjustable. Both front and back can be adjusted. Comes with anti roll bar linkage for the front as well.
All you need to do is to skim the front lower arm by abt 1mm to fit in the coilover. I would say they are the best suspension setup ever for aveo. If you only install those lowering spring from Apex, H&R, Vogland,the original shock is too soft. If you installed koni shocks, they are hardness adjustable but not height and preload adjustable.
Each set should cost abt $1.4k US.
