So, the springs i bought from ecp were for the non st mondeo, had massive wheel arch gap and the car was creaking like mad.
After getting part numbers from ford dealer, contacted ecp and they said "yeah its wrong springs and we dont do st220 springs".... Eugh.
Jacked the car yesterday and put the old springs back on and got a refund for those other springs.
Thinking to save hassle ill just buy oem springs from ford, pfft they wanted nearly £200 trade price for 2 springs. Sod that!.
So atm i have new shocks on the back but my standard springs.
I didnt want to go this route but it looks like i'm going to stick either eibach or h&r springs on.
I'm leaning more towards h&r's as they are apparently slightly better on track and since i track my st, might as well go with them, but on the other hand, everyone who has stuck eibach on have praised them.
Also, for anyone who has went this route, did you need to put spacers on?, if so what size?.
