Cus I've never heard of it until yesterday. I got my car back from getting subframe connectors installed, and one of the mechanics asked if I had been to the track lately. He told me that it's dangerous to be running out there without a driveshaft loop. Wha? He told about a Cobra that was running and broke his driveshaft and it tore the mess out of the car cus it flipped it. Somebody fill me in on what they are and what they do. Thanks
