yeh we know. but by puting 5 different locknuts on a rim isnt safe as locknuts arnt as strong as ur ordinary nut(so i heard).
i reckon tilt sensors are the way to go. at least u will hear it go off if they try and take them.
I work in Sunnybank sometimes doing nightfill shifts and I've had my VL broken into in the car park there, tried to take the car but i have an immobiliser (which paid for itself that night). And I've also lost some chrome valve caps. I'd hate to lose my 18s there, so I always park in the disabled bay right near the front door of my work. And of course there's no security or surveillence, and we can't park in the locked undercover area. A mate of mine had his VK stolen and burnt out from that car park too.
Even an alarm with just shock sensors will stop them from jackin it up. Doesn't cost much for an alarm with shock sensing. Bout 300 installed. Mine even went off when a guy tried to get my valve caps for his push bike.
