Sport Category allows any factory spring from your car, option package for street use from the same generation and factory accessory catalog springs meant for street use - along with commonly available lowering kits.

As with shocks, we have limited you to lowering kits you can find at the Tire Rack which meet those descriptions. You don't have to buy it from there, but if it's there and is a simple lowering kit, chances are you're good to go.

If there is a lowering kit you really want that isn't available there, and meets the intent of the rules - you can check our "Alternate Approved Springs" list, or use the "contact us" page to request a lowering kit get approved.
