1991 C2 ABS Brake upgrade


Vehicle Information: Year: 91; Body Type: Coupe; Total Mileage: 45k;

I would like to upgrade my ABS brakes. In checking with the Porsche parts dept., they found two changes from the 91 C2 to the 92-94 C2 and RS. The electronic control unit for the ABS had a different unit(part # had an 01 vs. 00 Suffix) and the pump was changed from a 964 part # to a 928 part #. Are these the changes I would need to make to have "RS ABS Braking"? Is this an easy/bolt-on upgrade? Would the control unit alone provide significant improvement?Thanks for your assistance.
