i just droped it 4 inches from stock height
i did not use the jdm bumper i just made the body kit fit it not that far off no cutting and no mods to the rear
the solinoid pulls the latch the same way as if you were lift the handle the p5 latch alow you to have a direst pull making it so that not alot of force is needed anything over 15 pounds is getting to big to fit in the doors i tried the 35lbs one but the wouldn't fit if you wanted to roll down...
i did everything other then the welding it was fairly easy and all you need is the 5 channel door popper kit from autoloc AND 4 door poppers you can get it all from www.autoloc.com
