Not sure what you are doing on this thread. I've come and read it several times.
Lowering the car is easy as there are several vendors on here that will help you buy the right springs. Mine was lowered using components that are no longer available so I can't send you to them.
Now how do these adapters make the wheels stick in less? I think a good alignment should make the wheels sit in better as this needs to be done once lowering springs are added anyways.
There's a thread on here recently with the different alignment specs you would want to use with a lowered Camaro based on the different styles of driving.
