Yeh there is some debate as to whether its 20mm or 30-35mm with the Eibachs but ppl say its 20mm because the ST is already lower than a standard Fiesta. I have had my car lowered by around 45mm on coilovers and had no problems with scrubbing etc.

You MUST get your tracking done about a week or two after the springs have been fitted, because by then they have settled. Any tinkering with the wheels and suspension will knock it out. This will save you from uneven tyre wear.

Although our member who has lowered his by a whopping 60mm looks cool, I wouldnt like to see how quickly his wheel bearings etc wear out!
