The e-brake for an “S” will not bolt to the carrier hub assembly on a base model, the bolt pattern and brake shoe diameter are different. To do what you are trying, you need to swap out the suspension carrier assemblies and hubs for those of an “S” model (different because of the 6 speed), which is going to be a lot of work and very expensive unless you get parts out of a wreck.

A couple of companies used to make conversion kits to do this, but they are no longer available as most ended up causing more problems than they solved. At one time, Brembo actually produced an “S” rotor that was internally machined to accept the base model brakes, so all you needed was a shim to go under the rear “S” caliper mount on the hub and everything fit. While this setup worked perfectly, it is also no longer available either.
