So......I found the answer. Not the same spring rates. More for street driving.

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!
