Road Magnet's Mazda Speed 6 lowering springs are a step above the Mazda Speed suspension. Looks better and handles better and comes with our 100% guarantee. The drop in the front is 1.4 and the rear is 1.6 and balances the car better.
I also have the Road Magnets and love them. The drop is right down to the tires. I don't think I've put more than 400 miles or so on them, but they are great so far.
