S! CCF Family.

I have Tenzo-R lowering springs on my daily driven 2007 Cobalt LS coupe. The drop/ride is nice BUT I am not satisfied. I am all about my vehicle's drop and stance. I considered trying one of the following lowering springs: B&G, H&R or Pedders. I'm not sure what to do. Should I just save up for coilovers? If yes, then which brand? I love the drop and stance of the Cobalt SS in the Stance GR+ ad below. What would I have to do to achieve this drop and stance?

I'd also like to know what tire size you recommend. I am currently on 215/45/17 Bridgestone Potenzas. I've read using a larger tire will fill the wheel gap a little more. Maybe what I need is a larger tire to achieve a better look on my Balt now.

Thank you,

Here is an older picture of my Balt on my current setup - 17x7 inch wheels and 215/45/17 tires (my tail lights will be slightly darker this weekend):

that balt in the pic is about the lowest you can go without snapping axles. and they'll probably break on that one eventually. i've done a lot of research on getting slammed. even experimented with it. it takes a lot more than coilovers. my next project is 25mm spacers with some camber shims and camber plates. should look dope.
