upgrade suspension

I own a 2007 Aveo notchback.
I want to upgrade the suspension and improve ride comfort.
Any ideas?

I hate to say it but the stock suspension is the most comfortable outof your options lowering it will be a stiffer ride but improve handling. You could look into braces that will decrease body roll and not make it tough on corners strut bar front and rear and maybe lowers to.

Thanks,
i really like the car just wish the ride was smoother

Could be that you may need to replace the shocks/struts.

Get some replacement KYB struts and top hats. That will help. Your control arm bushings might be worn along with your ball joints in which case it might be easier to just get new control arms with bushings and ball joints. I'm happy with the Raybestes I installed a little while ago. Also chassis bracing will actually help remove noises that the car makes going over bumps. I have done quite a bit in this regard including new rocker panels, front lower core support, chassis foam, and a control arm brace.
