Not too sure what a 'lowering module' is but as for lowering kits, keep an eye out for the 5thGen offerings coming out of SEMA.
54 corners?To lower the Camaro will be just like lowering a G8. both are Zeta platforms
All 54 corners have struts and the springs will have to be replaced.
There are some interesting suspension items on the ZETA if anyone is interested
