Hi all, this is a pic of my sisters golf. I'm wondering how much it has been lowered by

.
I've had a look at the springs and dampers, the springs are red and the shocks are yellow, anyone any ideas what make they could be?
The second problem i have is with the wiring. The last owner has put a wire from the back of the fuse box and linked it to the back of the rear heated window switch. The problem is that when this wire is disconnected the wipers, heater fan, rear heated screen, rear fog light and stereo go off and work again when its re-attached. This wire becomes very warm when everything is turned on and i am a bit worried about a fire. Anyone any ideas?
