I have the Ls cobalt and I'm in the process of lowering my car. I finally got my subs put. The only thing about the subs it dims my lights now. two 10's Pheonix gold octanes, with 1000 watt Ma audio amp Mono. My problem now is lowering my car. I took the stock 15" off and put 17" on. Running with 225/45/17 Kumho 711, with a MB Drift wheel Black with a polished lip.with 4-100 with a 30+ off set. All and all cost me about $630 at my cost threw work. My problem is I put the 17" on hopeing it would lower it but raised it 3/4 inch. I'm debating on how much of a drop I should do. I can get Eibach Sportlines for $205 at my cost for a 1.5f 2.0 rear. Should this be enough so I dont have to roll my fenders. Heres a picture.
Yes on the side windows is the cobalt sticker.

 

I wish I knew more about lowering, I'd give you a hand. I wanna get mine lowered too. DallasCobalt lowered his and it looks nice. I think Japeatr did it for him. Might wanna ask them.

 

i lowered my car myself with sportlines man, if you have any questions pm me. its really not that hard

 

You should be ok man. People on here have 20's with Sportlines and subs without rubbing issues, I'm pretty sure you won't have to roll the fenders.

 

ksport-search em. there real cheap and a great drop. here is the link to my before and after-here it is!

 

I can get the springs real cheap. I wont have to pay for them down front. My warehouse stocks them and It can be taken out of my pay check weekly to pay them off. I'm thinking about dropping it about 2' with the sportlines. The springs will cost me about $200. I'm just woundering if 2" is going to be enough.

 

you'll be ok. Im runnin the same sizes and Im still good. I put the sportlines on and no rubbing or anything.

as long as the plano you live in is plano Texas, when u get ur springs lemme know and ill help ya or if you wanna take a look at my car and see the gaps and all just say so.

 

How much off a drop did you do on yours.

 

Our sportlines dropped our 2.2s quite a bit, around 2.5" all around

 

I order my springs today threw work. I'm getting the sprtlines for my car. 2" in the front 2.5" rear. The cost me $216 straight from my warehouse with shipping.

 

my drop was the same^^^

i got em for 135 shipped.

 

How did you manage that. I'm talking about the Eibach sport lines.

 

how do you like the two 10s, they hit hard??

 

mine were 260 and Id pay that much again for them!! Like I said, if ya need some help puttin them on, call me. My number is on the DFW phone roster. I love workin on cars

 

the ones i have a basically the sportlines(same exact drop) for a way cheaper price.
