Anybody ever heard of k2 lowering springs? I am looking at another car saturday and he said he has k2 lowering springs and I was just wondering if this a quality part. i looked it up online and found this Ford Mustang Lowering Springs. Wondering if anyone has used these at all. My other question is how low of a drop is good for everyday driving. The car im looking at isnt lowered and im afraid a 1.5 inch drop is gonna scrape in everyday driving.
