**** eibach O_o the prokit is the exact same stiffness of the STOCK IROC/Z28 springs O_O only its 1" lower...so I would buy other springs. Such as global west or ground control. Me personally am going to buy coil overs. Where you can choose the stiffness of your springs. I'll probably getl ike 800lbs springs. Bye bye body roll

I like my Hotchkis springs. A bit stiffer then stock. 
And with all the pothole filled roads around here, I'm not sure i'd want to go much stiffer.

I've got the moroso trick front springs and they're great!They'll take a little while to settle and you might even need to cut them a bit for desired right height.But if you're after weight transfer, these are the way to go.
