These King coils are for a lowered height application. They should sit your commodore 25 to 30mm lower then a standard commodore when it was new. If your coils are sagged then your commodore won't sit much lower with these coils.
You may want to consider shorter shocks to eliminate the risk of your coils falling out.
These coils are a bit heavier duty then standard so you won't experience as much body roll and will feel a bit firmer.
However, body roll is generally caused by stuffed shocks, it can sometimes be a good idea to change your shocks at the same time anyway because you do have to pull your shocks off to fit the coils and shocks don't last forever.
King coils are made on the sunny Gold Coast in Queensland and come with a lifetime warranty covering breakage, faulty manufacture and sagging (Free height of coil dropping more then 10mm). In the past couple of years Kings have improved the quality of the steel they use. It is about 20% higher tensile.
