    One thing I would like to see along with the drop the manufacturer says is the actual real world numbers. All of these springs I have seen on cars at this point. None of them come even close to advertised. Especially the h&r. Supposedly a 1.4" drop up front yet they leave a half inch of wheel well gap on a car with only an inch to begin with. How do you advertise a 1.4 drop and ship a .5 drop spring. I would be suuuuper pissed if I paid for them and the front drop wasonpy 1/3 what they advertise. What they advertise is good to know, but real world specs are what I want to see from installs. Not just what they do on paper. Like with the h&r springs I tend not to trust what's on paper.

    I would like to see specs on those. The sport lines usually offer a bit more drop then the pro kits do.

    Could you please add spring rates and denote if they are linear or progressive? To many of us (myself included) that is more important than the drop.

    Stock ST:
    Linear

    Front: 171lb/in
    Rear: 183lb/in



    Eibach Pro-Kit:
    Progressive

    Front: 153-193 lbs/in
    Rear: 171-216 lbs/in



    Cobb
    Progressive

    Front: 154-194 lbs/in
    Rear: 171-217 lbs/in



    H&R Sport
    Progressive

    Front: Will not release
    Rear: Will not release

    Very few companies publish spring rates. They are extremely important escpeciappy wheel lowering. To soft and the car will just ride and handle like crap. Personally I prefer to have zero fender gap but spring rates that match that amount of drop height. The lower you go the stiffer they get, or should anyhow. It doesn't bother me if the ride is a bit rough though. Not if it looks and handles that darn good!

    Agreed on the rates. What scares me is the Cobb and Eibach springs are softer at rest than the OEM spring and don't get appreciably stiffer when at full compression considering they are both 1" lower than factory. Once we have a good selection of upgrade dampers (talking to Grayson at mc2racing, Bilstein will be offering some shortly) I would like to see linear springs around 225lb/in front and 250lb/in rear for a street car, 1.2" front/1.5" rear. For something more aggressive, 325lb/in front and 375lb/in rear at 2.0" front and 2.25" rear. Just throwing some numbers out there, but what's available now is too soft IMO to help performance.
