    This has been bothering me for some time.

    I suppose my suspension has started clunking in a way. I guess when any kind of travel on the front it makes noises like its banging around.

    I can lift the front up and the springs have a inch or so of open play up and down on the coilovers, then when i have to lower them i have to re-position them into place every time. Is that supposed to happen? it seems the springs should always be under tension.

    To me the sounds that my car makes are like the springs are moving around and bouncing.

    I currently run the UPR K member kit with 350lb springs with bilsteins.

    Is there a different setup someone else recommends? I just want a street happy comfortable quiet ride. Its humiliating to drive the car because of this.

    When i lower the car back down and position the springs on both sides, the front suspension is quiet but after 15-20 mins of driving starts to sound like a spray paint can, The springs won't stay in place it seems.

    Man I had an issue years back on my 95.. can't remember how but the spring would hit one of the bolts on the CC plates. . It would make a chunk sound at times kind of pop

    What cc plates do you have? Usually the noises are mainly from the cc plates. Also check to make sure your top strut nuts are tight.

    If you want a quite comfortable ride, it would be easiest to go back to a standard spring/strut combo.

    For coilovers, if you look around you'll see that MM makes a very good setup. I run their stuff on my car with billisteen struts and appreciate how their web site explains the tech behind their design. check this out for more info:

    If the spring free length is shorter than the strut at full droop, the spring will become unseated when you drop the suspension. However, this should never happen when driving around, since you would never generate that much droop, unless you are taking that car for some sweet jumps. BTW, just to throw it out there, I may be selling my full MM Koni kit, since I want to go to Bilsteins.

    Oh, I'm not looking for regular Bilsteins, I'd be buying an all new kit from MM, Race 2 series. As far as my kit goes, it's Koni SA shocks and struts, MM coilover kit front and back with 350 lbs front / 250 lbs rear springs. I can also piece together a helping spring kit for the rear, if you'd like. Those are for keeping the rear springs seated, because rear droop is a lot more than free length of spring. MM typically doesn't recommend coilover kit for the rear street use, but I found a way around that.

    Two questions,

    1. Are the coils that you are using? are they MM coils with the coil over kit? if not are they the same diameter as the springs that came with the kit, assuming you might have switched them out?

    2. How long are your current coils? maybe the current ride height is effecting it. could you resting on the shocks? and the coil not be under enough tension

    1. * They are UPR, i ordered a UPR kit and used the supplied stuff. -- http://www.uprproducts.com/mustang-pro-seris-coil-over-kit-springs.html


    2. * They're 12 inches/350lbs. I feel that is the case, which brings me to my theory about the shocks not fitting in the sleeves correctly. Bilsteins require a specific kit evidently and i didn't know this.
