I'm looking into lowering my car soon and I was wondering, when I do choose which springs/shocks or coilovers I want to go with, should I upgrade anything else as well or would doing just them be ok to do?

I Have an 09 cobalt ss btw

 

steering rack spacers will help.

 

Endlinks

 

So, just the endlinks and spacers and I should be ok?

 

Yeah, probably. Spacer thickness will depend on how low you go and endlinks you can buy are Moog/Powergrid

 

Which would be better to get? Powerlinks are adjustable, but would I really need that?

 

Not necessarily. They're really expensive, but they'll probably last the life of the car. Adjustable and doesn't need to be serviced.

Moog endlinks have greasable zerks that should be serviced every so often, but they're really cheap to replace if you do break them. Like ~$40 for a set.

Go with Moog.

 

Moog makes a good product, those should be just fine.
