    Question Any interest in urethane rear spring isolators?

    One of the aftermarket companies has just released a urethane spring isolator kit for the 99+ IRS Mustang Cobra.

    Why do we care? Because the lower isolator for the Cobra is the same part number as both the upper and lower isolators on the MN-12 platform.

    I told them this, and they're sending me a set to try. I'm confident that they'll work, and eliminate one of the problems in the rear suspension as the stock isolators don't last very long.

    I'd like to be able to tell them that there's a market for this kit, priced below $40, so post if you'd be interested.

    Thanks

    I would be interested IF they are dimensionly the same as new stock pieces. Once you get them PLEASE measure the dimensions and post them so I can compaire them. My rear suspension is totaly disassembled right now so I have parts ready to compaire things to. (in case yours is not apart yet)

    I want to talk to you. [email protected] (that's lower case QTM.NET)

    I believe that the source of Wheel Hop in Ford IRS cars is: The Large Squishy, rear sub frame isolators. Is this what you are talking about?

    LETS TALK!!!!!!!!!!!!!

    No, I'm talking about the coil spring isolators.

    BTW, I don't have wheel hop. A 1 3/8" sway bar, air bags, H&R springs, Tokico shocks, MN-12 knuckle bushings, and DR's cured it for me.

    Well, All of us 5-spd guys know what Doesn't Work! Hopefully I'll find something that DOES work!

    I apologize! Most people who respond are AOD guys. I responded before I saw who you were!

    My 1 3/8" F&R sway bars helped through the corners, but DO NOT help at the strip. Please do not quote solid axle dynamics, because they simply do not apply to IRS!

    IRC: Two schools of thought here.

    Theory (1) With the suspension in soft, disconnect the rear shocks. Then put the front in FIRM. Theory: The rear will squat & the front will raise!

    Theory (2): Put the suspension in HARD, then disconnect the Front shocks. Theory: The front shocks will stay soft, while the back shocks are hard. Result is that the rear is stiffer & doesn't hop, & the front responds to the weight transferr.

    Which thinks you?

    With my SC, 2 is the answer.

    I really don't want an argument with you. I know what works for my cars, and I've got the numbers to prove it.

    And, this wasn't the reason for this thread in the first place.....
