I know that EK9 Hubs are the same wheel fitment and brake rotor as the 98/uk spec DC2 with 5x114.3 stud pattern.
Ek4 is 4x100 fitment and 96 4 stud DC2's are 4x114.3, which is the same as the mb civic that comes with b-series engines. Heard of a few guys using the brake setup off the mb civic as it is 282mm compared to 262mm.
Hope this helps.
