Just a bit of an update to this....after a year of driving around on the Tein springs I finally decided that they were way too harsh for my local roads, these old bones have protested enough
So I have swapped the Tein S-Tech -35mm springs for Eibach Pro-Kit -25mm springs, all I can say is that the comfort level has increased massively, the Eibachs seem to be able to soak up the annoying ripples and bumps in the road surface but still feel nice and firm when throwing it into the corners (maybe because of their progressive nature). The only downside is that the car sits slightly higher and looks a little less agressive, but I suppose you cannot have everything.
