DSSRs are pretty fantastic, I have one with my m52. I hadn't driven the car without the dssr, but fiddling around with the shifter (making driving noises) before and after, I did notice a difference. And this was with all new bushings too.
Also, where were you going to get your DSSR from, I paid $150+shipping for 2 of em (e30 and e36). I think I got them from turner
