4000 Series Plain Rear Rotor for the First-Generation WRX

For the 2006-2007 WRX, this 4000 Series Plain rotor brings DBA’s core metallurgy and manufacturing process to a smooth, OE-style rear rotor, without any drilling or slotting.

Built on the Same Foundation as the Rest of the 4000 Series

Even in its plain-faced form, this rotor is cast from the same high-carbon alloyed iron and put through the same Thermal Stability Profiling as DBA’s drilled and slotted variants, so the underlying quality doesn’t change just because the surface finish is simpler.
