Since there has been so many requests for pics and info of specific springs (ie H&R , Eibach, Progress, etc...) I thought we should have one thread we can post pics in to see for ourselves and follow one template for info on the springs.

You know that is going to screw up your speedometer right? You are going to read faster than what you are actually going. If you are actually travelling 60.0 mph then your speedometer will tell you that you are travelling 64.2 mph. This is also causing your odometer to roll over faster than necessary, thus reducing your resale value since the car will display more miles than actual.
For instance, if you use this tire size for 30,000 miles of actual driving, your car's odometer will display a reading of 32,292.8 miles. This is of course not an issue if you recalibrate your speedometer with HP Tuners.
Not to mention the lack of ride quality, less sidewall = greater chance of denting wheels on potholes. You are also going to be more prone to uncontrollable wheelspin in first gear, thus probably having worse 60' times if you ever race.

You would want to run a 215/45/17, this would put you closest to your stock size of 195/60/15.
Overall tire diameters:
195/60/15 = ((0.60 x 195mm) + (15in x 25.4mm/in)) = 24.2 inches
215/45/17 = ((0.60 x 195mm) + (17in x 25.4mm/in)) = 24.6 inches
225/50/17 = ((0.60 x 195mm) + (17in x 25.4mm/in)) = 25.9 inches
Incase you have noticed a trend here..the outer diameter of the tire is what matters, this determines your tire revolutions per mile. Your LS is configured for 24.2 inches stock.
Since all Cobalt wheel wells probably provide the same amount of clearance, I would probably venture to guess your tire size limitations would not be any different than say an SS/TC. So...
Tire size max on SS/TC (with 17 inch wheel~safely): 235/45/17 OR 225/50/17
However, if you choose one of these sizes, you will want to have your speedo recalibrated.

First- my car actually rides better,because my old tires had no more miles left on them, and i still have the same set-up as before.
Second- I have gotten a new best 60ft ever a few weeks ago at a 2.09, before my best being a 2.22...it just suck because the weather wasnt good. okay

^I'm hoping my car will look that nice...gap wise I mean...can't wait to get my MSR 045's on next year...will be buying 225/40 18 Bridgestone Potenza RE760 Sport tires for them. And of course I'll have SS/TC struts on my Sportlines by then as well.

depends what your looking for as far as how far it drops, what the road conditions are like in your area etc. theres no real BEST spring, just better springs for better applications
