Innovative Mounts 96-00 Civic K-Swap Rear Bracket EG Subframe - Part #90031-SB
If your EK K-swap is built on an EG subframe and rear crossmember, the rear bracket has to match that setup rather than the stock Civic one. This is that bracket, sold on its own for replacements and for swaps being put together a piece at a time.
What It Is and Why It Works
Rear sub bracket for a 96-00 Civic running a K-series on an EG subframe, with all hardware included. It fits every K-series engine, so K20 or K24 makes no difference here. The rear position is where a swapped drivetrain tries to rotate under power, and a bracket built for the wrong subframe puts the rear mount at an angle it was never designed to work at.
Single part, no bushing choice. The decision that matters is which subframe is under the car.

This bracket is for cars running an EG subframe. If your EK still has its stock subframe, the rear sub bracket is 90030-SB and the mount kits are 90050 and B90050. The EG subframe mount kits are 90051 and B90051.
What to Know Before You Buy
Know which subframe is under your car before ordering. EG subframe and stock EK subframe K-swaps use different brackets, different mount kits and different rear crossmembers, and the parts are not interchangeable. This is the single most common source of wrong orders on EK K-swaps.
Check the bracket that is on the car if you bought the swap already done. Used K-swaps often carry brackets that were drilled, cut or borrowed from a different kit, and the rear position is the one where that shows up as movement under load.
If you are buying parts for a fresh swap, get the mount kit and brackets together rather than one at a time. Parts cannot be returned once they have been bolted in.
