1) Stock xi rear bar is solid 15mm.
2) Stock spring rates should use: UUC front bar, H&R M3 rear bar
3) KW V1 Coilovers: e90/92 M3 rear bar
4) Buy the M3 rear bar from HPAutowerks or Tischer. Use the google machine to figure out the best price for the UUC/H&R.
The above is the answer to about 90% of the suspension questions out there. No more excuses that you can't search.
