New Official Cadillac "Suspension Modification Kit"

Cadillac has a new performance suspension kit available on their website. I haven't seen this before so it must be a fairly new addition. I'm looking into the changes made for the kit, but it is possible they have adapted some parts from the V-spec car to be used on the normal cars. As far as I can tell the kit includes new springs and stabilizer bars.
