How much tire gap (the space between the tire and the body of the car) do you have? If you have 1.5 inches or less you can raise it safely, by buying the stock suspension that is, if the suspension that is on the car now is aftermarket. Aftermarket kits are usually a different color than stock coils. If you can, look under there and see what they look like. If they are aftermarket coils, it should say the brand on the coils.
