Cat sx2 NO Eccentric; CNC Alloy ???

[purplenut]

Just been looking closely at the new cat sx2 as iam thinking of getting along with the sv.
But i see altho they have the Eccentric; CNC Alloy in the parts list they dont seem to be on the car on the site?.
Just wondering if anybody know if they will come in the kit or we have to buy as a OPTION part,if so i think that stinksand i bet its to do with cost.
Thanks.
