Road Magnet Lexus IS 300 lowering springs will really improve the cornering for more of that Team Lexus race car feel. These springs are also used on Team Lexus race cars in Puerto Rico.
If you are looking to put anything other then stock springs on your car, for the price I do not think you will find a better value then the Road Magnets. These springs were researched, tested, and have recieved great reviews.
