2004-2007 Cadillac CTS-V Appearance Mods Discussion, Lowering springs in Cadillac CTS-V Series Forum - 2004 - 2007; For not much more expense (+$200) you can avoid the H&R springs, spacers etc. an go to a full coilover ...
How do I know or how can i find out what oem shocks I have. Site asks me what shock I have.

- H&R spring part # is 50781 - google for it - cheapest price will come down to the spring and shipping cost (redline360.com has them for $258ish)
- MM spacer kit for the rear
- McMaster Carr Rubber spacers and Z06 endlinks are recommended, iirc
