Alfaholics Power Steering Conversion for 105/115 Series

£4,050.00 GBP (ex vat)


We have recently developed this superb electric power steering system which fits into the original steering column and is concealed from view under the dashboard.

The system is speed sensitive (by taking a pulse from the speedo cable) and is therefore able to provide increased assistance at low speeds when parking and manoeuvring. As the road speed increases, the assistance gradually reduces until it reaches a minimal level by 30mph/50kmh, so as to retain the lovely Alfa steering feel. Torque sensors in the steering column continually feed data to the electronic control unit in order to apply the optimum level of assistance, according to the road speed and steering input from the driver. There is also a safeguard built into the system whereby assistance is limited if the road wheel encounters a solid object, such as being parked up against a high kerb, thereby preventing damage to the steering box.

We originally developed this system for the Spider-R V6 project and were so impressed with the results that we have fitted it to several other builds including our new GTA-R 290 project, ensuring it is as comfortable cruising the streets of Monaco as it is competent at lapping the Nordschleife in 8mins!

The conversion is carried out using your core steering box and in conjunction with a full steering box rebuild using our CNC machined billet casing for additional strength. This is particularly important, given the well known cracking issues that affect the original cast aluminium casings. We also require the aluminium column switch mounting shroud in order to complete the conversion. When refitting, a small modification is required to be made to the box section under the dash to clear the motor, so the installation should be carried out by a competent engineer. We offer a full installation service here at Alfaholics.
