I want the lowered look but I dont want to kill the ride. I have the 18inch stock "fanblades" on my 06. I've heard the factory made some(adjustments?) for the 18 inch wheel options for the 06 models as well as softer springs for the convertible on 05 & 06 regardless of wheel option. So...my question? will the (lowering) spring kits for the coupe work on the verts and will the fact I have the factory 18 inchers matter at all?
