Changing M2 springs for daily driver duty?

The OEM suspension seems great for the track but leaves something to be desired on the everyday crap roads in NY. Has anyone toyed with the idea of changing out the springs for daily driver duty?

The springs are fine. The OEM dampers aren't the greatest and don't have the proper damping.

You will find coilovers out there with higher spring rates than OE but still rides better.

Are you feeling lots of impacts from the road/bumps and wish there is more control or less floatiness?

I'm feeling incredible harshness and crashing suspension pieces when I drive to work on the interstate when I bounce over ridiculous frost heaves in the pavement

There is way too much compression damping built into the OEM dampers, that is why you are feeling all the harshness.

Changing the springs will likely not help unless your springs are binding or you are hitting the bump stops.

Ok so what aftermarket setup do you recommend to improve ride quality on harsh roads while maintaining track performance?

One of the best kits out there for that would be the Ohlins R&T with the optional spring rates.
