I'm wanting to lower my car soon and would like some suggestions on which one of these lowering options are the best for mt 2K Max with 17in rims. Thanks.

 

GC coilovers suck ****. they'll make your car bounce like a **** if you slam it.
imho,
performance: eibachs.
ride: H&R.

 

Depends on what you plan to do.

Standard lowering springs are good enough.

I've ridden in ChrisV's GC/Koni setup and it handled much better than Eibach/Tokico-- rode OK-- stiff but not jarring-- but his car was not slammed either, since he auto-x's and needs the suspension travel. Cattman coilovers still rule over all though...

So for most people I'd just do lowering springs.
