what parts from the ST suspension would be compatable with the NA MK3? I noticed that some companies are offering springs for the 2014 ST mk3 that will not fit the 2013 ST. I'm wondering if it is for the same reason that the 13 springs will not fit the 14 NA MK3 and then if those springs would fit a 2014 NA MK3? Also, if i were to put ST struts on a NA Mk3, would i then have to use ST lowering springs too? or could i still use the NA lowering springs?
