Nothing works as good as a stock door handles. If this is a daily driver I highly recommend not doing this. Always, have a backup way to get in if the battery dies, remote stops working or the door pop quits on you (usually quit from a poor ground). Most people install a button that will pop it when the remote stop working, which you can connect a battery to if the battery dies. But, not really any type of backup if the popper stops working other than a key to the trunk/back door.
IF an older Burden use a trunk pop if you build your own kit. Most door pops don't have enough pull for older cars. If you have a current car alarm with remote trunk/door capability you can use it and just pay $75 for the actuators, wiring, and relays. Do your homework (easy money unless your confused by relays) and go for shit.
