Mitsubishi Dogbox & Sequential Gearbox

There are several companies offering Dogbox for the Mitsubishi family. Dogbox are transmission which do not have synchros. The have a diffrent type of engagement which allows clutchless shifts. Some manufacturers make them utilizing straight gears while some still retain the helical gears like the OEM. Straight gears can be noisy and would not be suitable for a daily driven car but what the heck, dont we love the whines of the gears.
