Thanks
And yes, the GMPP kit comes with everything assembled and ready to mount on the car. Minus the anti pogo retainers but they arent needed for the GMPP kit.
GMPP kit consists of...
Adjutable Koni struts
GMPP springs
Strut mounts
All assembled for you from the factory.
If you go the other route then you will have to buy those things on the list i gave above, then rent a spring compressor to assemble the strut and springs to the strut mounts before you can install it into the car. From my experiance it takes almost as long to assemble them it as it does to install it...
If your going to save the cash then the GMPP lowering kit is worth the money at around $900 or so plus it comes assembled and with adjustable konis...
buying seperate parts will run close to $600...then you got to assemble it yourself.
Its all on what you want to do
