    Get a hold of Don Lariviere (hmark on the national forum). I know he's just bought a pile of springs for his sn95.

    I don't know nothing about Global West -- never needed to get anything from them.

    But if ytou're looking for stock-style springs in a variety of rates, I'd check the circle track shops -- specifically Speedway Motors. They have both flat-ground and OEM Pigtail springs from various manufacturers plus their own in-house brand. That's where I got my 575# rear springs. Very good, and very cheap.

    Rob,
    Pretty sure Robert is running a Torque-Arm rear, so that's not too unheard of...

    I'm running 350lb rear coil-overs, so the motion ration put them somewhere around 785lb-in conventionals.


    It's all about wheel rates:

    Springs in stock locations on a Mustang.
    Frt, Spring Rate X .25 = Wheel Rate.
    RR, Spring Rate X .49 = Wheel Rate.

    Coil-overs on a Mustang:
    Frt, Spring Rate X .9 = Wheel Rate.
    RR, Spring Rate X 1.1 = Wheel Rate

    Yep, 575# springs in the OEM location, custom torque arm.

    575 works pretty well for TWS. Not so good at ECR! Al can attest to that. :roll:

    You may be right. It's certainly too much spring for ECR and probably Hallet too. 450's may work better at TWS too. I'll have to give it a shot. Rear springs are cheap...
