So whats the difference? Both have same spring rates 275# front 500 rear?

So..I Found the answer! Not the same spring rates>
Yes! With our GMPP certification you can order our GMPP certified parts through your GM dealership. We've been working with GM on GMPP certification since they contacted us to collaborate with the GMPP/Pratt and Miller special edition SSX car.
Keep in mind there is a difference between the GMPP coilovers and our normal Camaro coilovers. After talking to GM about their goals with the SSX project, we decided to use a slightly lower spring rate which allowed for a more complaint ride on the street and to allow for more ride height adjustability.
Both coilover packages will give you an excellent base for a street/track Camaro, but the GMPP coilovers were designed with a little more street use in mind.
If you've got any questions please feel free to ask. Thanks!

Thanks for the question chuckclanton. There are a few differences, the most important being that they don't share the same spring rates. Besides the spring rate difference, Pfadt GMPP coilovers give you an additional 1/4"-3/8" lowering capability which will give you a lower center of gravity for enhanced cornering, as well as better aerodynamics which will improve your mpg in ideal conditions. Hope that helps, give me a call if you have any more questions and we can talk you through it!
