Put a full Suncore spring conversion kit on my 94 Mark 8 Changed out the rears first as the back had dropped and it needed fixed first The series 2 kit is going to be modified soon In my opinion the rubber isolators are the wrong size for the springs they sent and only cover half of the surface contact area of the spring If they shift at all you'll have steel spring on aluminum lower control arm I contacted them and they explained they were the correct items ooookkkkkk Same for the top only steel on steel if it shifts No lower cup as in the series 1 kit so the spring can get out of center and float all around in the recess and I don't like that either. No difference in noise when the swap was made with the rears Changed out the fronts and it drives and handles just fine The bad side is now the road noise is extremely annoying Three months after the swap one of the new rear shocks is leaking and I get to deal with that The Instructions could have been a lot more detailed all the way around Were it not for the forum to find where the control module is located to find the wire you have to clip to eliminate the air suspension warning I would still be driving around with the car telling me to fix the air suspension Changed out the 2 front tires from the shot Uniroyal Tiger Paws to a pair of Sears Road Handlers and aligned the car Looked around for any reports of excessive noise from these tires and have found none I am assuming the noise is from the new spring struts
