Our K series adapter plates are the highest quality adapter plates available anywhere. This adapter bolts a K series to any BMW E36/E46 transmission (Getrag 5, ZF6, ZF6), or to a Getrag 260 transmission from the E30. 

Unlike other adapter plates made of aluminum, ours are machined out of precision-ground 0.500” steel plate. By using steel instead of aluminum, our adapters are as thin as possible without compromising rigidity or thread strength.

Our plate design ensures that no additional flywheel mass is needed due to an overly thick plate, and the steel threads can withstand a lifetime of engine and transmission service. 

All plates are machined in-house and individually test fitted and deburred before being zinc plated. All of the required high-grade hardware is included, as well as new OEM BMW dowel pins. Our K to E36/E46 plate also includes a special machined K series engine side dowel.

Offset Degree Guide

• The offset Honda uses from the factory on Civics/RSX/TSX/etc: 15°
• 13° offset required for:
  • KPower K-swap 1990–2005 Mazda Miata
  • KPower K-swap 1982–1994 BMW E30
• All other KPower and universal applications: Use 15° offset

Notes:

• Use Honda flywheel bolt 90011-RDB-000 only.
• Use our Kpower flywheel with this adapter plate
• Some Getrag 240 transmissions use the ZF5 adapter plate and flywheel (community verified)
• If you want to replace the friction plate, we offer that part here.
