better car alarm?

Snakes709

I'll give a short story first. I have a silver 09 370z and my 08 Kawasaki Ninja ZX6R parked in my parking lot outside. They are parked side by side and very close...in some cases i have to slide over to the passenger side to get out of the car. My ninja has a Scorpio alarm on it and the sensitivity is as high as it can go. Last night the remote started going off so i chucked my shoes on and ran out the door. (bike theft is abit high where i live) So i get out there i see 4 teens walking away from the car/bike. I ask them "did you touch my bike?" they replied "didnt mean too, just wanted to look into your piece of **** car" So i said "dont come near my **** again or the cops are going to be called" Personally i would have done worse to them all but im in the army and ill get in trouble at work for getting into a fight. So i reset the alarms go back in and thats it.

This morning i go to futureshop...which is like a best buy and talk to my friend down there about a car alarm. I had a Viper 2 alarm on my Supercharged Cobalt and it was a good alarm. Talked to him about 2 types of alarm but when he brought the drop down menu up on the computer it only said 350z. Didnt have the 370z yet. Is the ignition system and wiring for alarms the same between the 350 and 370? I really wanna get a alarm in but i dont want to mess the wiring up if u need some sort of adaptor for the 370.

If someone could give me some info that would be awesome, thanks.
