have upgrade kits for ef-au's etc.
also RA alarm is quite good, approved etc.
jaycars alarm is also quite good.
quicktrak is the only other solution.
if you need prices/installation, give me a yell.
(alarm tech) lol.
ps. insurance does NOT care and will NOT give you a discount on your insurance for a car alarm on a falcon because it has smartlock, its not the EASIEST car to steal and their very common so they dont give a rats ass pretty much. Although with quicktrak which is about over $1000 installed is 10% discounted or more by nrma and others.
