I have Road Magnet Springs and they are just fine. I daily drive my MS3 40 miles a day all in the city and have zero issues with a bouncy ride quality. I've also autocrossed them 3 times now and even finished 3rd overall out of 81 cars (PAX scoring) I'd recommend the Road Magnets to anyone looking for a sportier feel, an autocrosser not looking to spend money on coilovers at the moment, or someone who wants a nice looking drop.
