I have a stock suspension 1988 mustang coupe the minitubs, and I was wondering if anyone had any experience with goo or bad. Looks to me you have to turn these upside down so the knob will at the bottom. Also, do these work as well as coilovers mounted behind the rearend housing instead of mounted in the stock location. The car weighs 2835lbs with driver. 54%front /46% rear. Thanks in advance. What length and weight springs do I use?
