    Hi Marc,

    I've heard that you have some wiring diagrams for a 1990-1993 Ford sierra.

    Would it be possible to e-mail me them over?

    Many Thanks

    Hi Marc,

    I trust this message finds you well.

    Sorry for the direct message but I was interested in what suspension settings you have and the way you have complemented the handling of your car. As a starting point, do you know what the stock/standard front and rear ride heights are on a 3 door Cosworth and where are these measurements taken from. I suspect that the front ride height is taken from underneath the front cross member and i also suspect the rear is from the underside of the diff? Any help would be grateful.

    My Best - Steve

    Hi Marc

    I was searching for tips on better brakes for my Escort cosworth, so found this thread that you had answered in

    https://passionford.com/forum/genera...e-upgrade.html

    I wonder if you would like to share you spec with which brembo calipers and which Mercedes model of front disc you use on your Sierra 4x4 cosworth?
