Here is my Corolla/Corsa electric power steering column after it was finished. The first pic sucks since it was with a phone. The rest are the column installed. From the hub to the tilt is Corolla. From there to the spline is a Vaxhaull Corsa C electric power steering column. The upper part of the u-joint is Corsa and the lower part is Corolla which attaches to the manual rack with a Quaife QSR quick steering rack and pinion. Most of the two columns were disassembled and put together. It was crazy how close most of the tolerances were between the two different columns. Most of the inner shaft is Corsa except the the Corolla spline that was welded on so It would accept the Toyota steering wheel. It has a control module to adjust the weight of the steering from one finger parallel parking to pull out the big guns no assist track days.
Finished Corolla/Corsa electric steering column.
The electric motor makes for a tight fit. The vent housing under the column had to be modified with a hammer.
The Corolla ignition, signal arm and trim all keep the interior looking OEM.
The Corsa spline that slides into the Corsa u-joint
Supra intermediate shaft leading up to the modified Corsa u-joint.
My Corolla/Corsa electric power steering column turned out really nice. I can use the OEM steering wheel, column cover and signal plus a Supra intermediate shaft on the opposite end. There's no draw on the engine and I can still run a manual quick rack. I have not track tested it to see how it holds up but a lot of guys use this Corsa columna for rally. All in all it's the second best mod in my Corolla, f22 still takes first.
