I believe that circuitworx used to offer 5-lug hub replacements. Don't know if that product is still available.

also the RSX type s rear calipers are the same as Type R as well so you can put it all together for alot less than the conversion you just need to research and be patient.

rsx/ep3 rears mount the ebrake on the bottom of the assembly, so you have have to swap the calipers from left to right to address the e-brake which makes your bleeder valve points down, so more work to bleed. Otherwise you lose your e-brake. Simpler to just get ITR rear calipers. Bolts right up to the regular 4-lug rta.
