I've gone coilovers on my fronts. I had the strut housings shortened so there was less droop using some Koni reds made for a Stag. I've heard the k-mac strut tops weren't real good, from more than one source. I settled on Noltec ones. a bit more sturdy. They should only rattle, or be noisy if the top bearing isn't secured tightly and can rattle in place. I still haven't got my setup installed on the car, but hopefully in a week or so they will be.
