I ran BC coilovers on my 08 MS3 in South Florida which were nice because the roads are good. I have been in St. Louis, MO for a couple of years and had to take them off quick. I ended up getting Yellows and used the stock MS3 springs.
I recently sold the MS3 and bought an 2005 MS3 sedan. I am going to run Koni FSDs and some spring... I'm actually looking for people who are running the FSDs right now to see what spring they are using.
Anyway, I would suggest trying to find someone with MS3 springs for sale and running the Yellows with those. Great setup for a DD.
