there is a guy in my local car club that just bagged his civic (bolt on kit). the kit was designed poorly, and the bag rubbed against the knuckle, and he sprung a leak . bags can be reliable........as long as they are done right. fastbag setups are fun to watch. I have a friend that is going to do air cylinders (can-overs) in his honda, and he is doing isolator valves for the cylinders, and a few other tricks. they say it shoudl be pretty stiff with teh isolator valves in place, so we shall see. I am sticking with my good ol' springs
