    First off cool user name haven't played that in a long time. Never seen the adjustable ride height, i'll ask if your more concerned about the drop or the ride quality? If you want a good drop the eibach pro-kit gives you a nice drop but not necessarily a performance spring. If you want handling then people recommend going to at least bilstein shocks and then your out spending at least another $400. It gets expensive.

    I am looking for good looks but I dont like to have some problems like wheel hop and so on. I think I will go for the pro kit and relocation brakets for LCA and hope for the best

    Ride height & Performance with SS stock suspension

    These look interesting to me since I am satisfied with my 2002 Camaro SS ride and handling, but I think it would look better and also handle better if it was a little lower. I love the fact that they are adjustable.

    I understand that these would replace the springs in back, but how would they work with the already there combo springs/shocks in front. From reading the comments, it looks like they might just replace the existing springs?

    Ah, if it was only that simple..... When you change heights you have to change spring rates to support the mass in a shorter amount of travel. When you change rates, the damping requirements change. In short, you can't (well, you can, just shouldn't) just slap coil-overs on and roll any more than you can do it with regular lowering springs (in fact it's more involved).

    GC kits remove the stock spring and perch in front (and dust boot) and give you a coil-over sleeve, perch and 2.5" race spring and adapter to replace it with. Similar thing in the rear, and the rears use bare springs (which rust immediately) and come loose when the axle droops fwiw.

    Thanks Sam, ....

    what would you suggest, keeping in mind that price is important, and I was hoping to stay under $400 to lower the car, and still have it street/track worthy. Can that be done?

    When you lower you really SHOULD do shocks too so when you factor that in no....

    Around $700 for SLP Bilsteins and springs or a little less if you go KYB AGX I believe. I may be off a little because I haven't priced this in about 2 years since my Koni/Strano setup went on...

    AGX's are $399 shipped, any decent spring will be around $250-275/set shipped.

    Sorry to say, you get what you pay for, and $400 to get a decent suspension isn't that feasible. Decent shocks alone cost that, let alone great ones, let alone springs...

    I use them with Koni 4/4's and sway bars from Strano. 550lbs./in front and 175lbs./in rear spring rates. They're a p.i.t.a. to get on Koni's 'cos the top of the Koni's is larger than the threaded sleeve, so you have to unbolt the cylinder rod end cap to get it on; not sure if Koni will warranty it after that, I'm assuming they will 'cos I didn't modify anything but I guess we'll see when it comes time for a rebuild. The only issue is that since the rear spring is so stiff, it is short, and if you lift the car by the body, you'll have to make sure the top of the spring gets back into the spring perch when you lower the car. Minor annoyance, but I think it's worth it 'cos I can never be unsatisfied with the way my car sits.

    Eugenio, you have any pictures on your car?

    I have an SS, just wondered what yours looked like with that combo.

    Thanks, but...

    I clicked on the picture on your signature and your user name, but only could find the enlarged photo of the one on your posts....the one with your car sitting in the woods on dead grass, front shot of car, with the wheels turned 45 degrees to driver's right.

    No big deal, I already did the hose mod, and am satisfied with that.
