SW20_3sgte
If i remember correctly the st184 series 2 may have actually run the twin pot brakes.
just for clarification.
all ADM st185 (90-93)and series 2 st184/5 (92/93)have the larger rotor/single pot calipers.
series 1 JDM st185 and st165s have a smaller twinpot.
series 1 adm st184 have small single pots
st162 have twinpots, but the disc is 3mm larger dia, but thinner than the st165/S1 st185
