I seem to remember that ali bearing carriers where intended for NASA Autograss specials (think adult bike powered caged go kart) that weigh around 350-400kg and the rear brakes don't do much work on a dirt track. There are good versions of them out there made from proper spec material and there's the ones made from common HE30 which will be not so good. As for being able to bend them did this car have slick tyres?

I have been altering the Corsa epas today.

I attacked the steering column today. The motor on the epas needs flipping 180 degrees because it will stick through the scuttle if you centralise the unit.



I cut the bracket holding the motor set up to the column , you cant just cut the rivets out because they are offset.

I spun up a bung to centralise the bracket while welding.




And mig welded the bracket back on.

I decided from the beginning to run the column over the scuttle rather than through the pedals to make it less congested. The adjuster on the column gives 550mm floor to wheel center to 650mm floor to center , that will make it easier to get in and out





It also makes for an easy route for the steering shaft with no nasty angles, it all clears the headders by about three inches and the uj`s will have an easy time. The sharpest angle is 30 degrees. just need a bearing block mounted off the top chassis rail to carry the steering shaft.

Epas control units have turned up. matching plugs as well

Blurb on them

Corsa Steering Controller - NO KNOBS!

Microprocessor based EasiPAS - Electric power steering assistance, EPAS controller for Corsa B or Corsa C steering columns, fitted or being fitted to any car.

This product is ready to install. All you need to do is to connect an ignition switched +12V and install your own momentary push button on or near the dash. Colour installation and user instructions available in English, French, Portuguese and Spanish. Comes complete with microprocessor based controller, connection wires, plug to connect the Corsa ECU, installation manual. You will need a (momentary) push button to match your dash style.

Electric power steering uses an electric motor to assist the driver’s steering effort. The Electronic Control Unit or ECU receives information from sensors and decides which level of assistance the electric motor should deliver to the steering you desire. Systems give more assistance at slow speeds and less assistance are higher speeds, as less steering effort is required to steer when the speed is higher.

When you install a Corsa B or C electric power steering in your vehicle it won´t work correctly because the ECU won’t have or receive information from vehicle speed and engine sensors. EasiPAS solves this problem, by giving you the lowest assistance level at all times which is sufficient for most kit cars and/or rally cars. However should you wish to park, simply press the button and you get a minute of high assistance, after which time the system will automatically revert to the normal low level of assistance.

HOW IT WORKS

When the engine is started the circuit waits 10 seconds for the Corsa EPAS to initialise, other products do not do this! During this period it sends no pulses to the EPAS. After 10 secs the circuit outputs an engine rev pulse to let the EPAS know the engine is running, if the EPAS does not get this signal it turns off to conserve power. After the 10 sec start-up delay the EasiPAS outputs for 1 minute a slow speed signal this will give you 1 minute of high assistance to manoeuvre, after which time EasiPAS will revert to the default state of high speed which puts the EPAS into the low assistance state (as if you are driving at 45+ mph). So you always have this low level of assistance.

Rather than an rotary knob our system uses a momentary contact push button, like a horn switch/button. If you press this button the circuit output goes to the low speed/high assistance state for 1 minute allowing you to park. After 1 minute it automatically reverts to the high speed/low assistance state. Should you need more time simply press again for another minute.

Power steering columns are retrofitted to many vehicles. Corsa steering is particularly popular as the columns are small and can be easily obtained at a breakers yard and online.

Typical applications: Rally cars, classic cars, AE86, Escort Mk1 Mk2, 7 Clones, Opel Manta Ascona Kadett, Westfield, Nova, Minis and many others.

Note this controller only fits Corsa B and Corsa C electric power steering columns.

Clever stuff. What made you go for PAS in the first place ? Although the steering is quite heavy at low speeds I've never felt the need for it. I wonder what the difference will be in steering feel ?

I went with the epas because of the 2.4 rack and the shorter arms on the modified mazda FDS3 uprights. It would be roughly as hard to turn as a 2.0 ratio rack because of the arms but at least it will have a very quick lock to lock response. It should still have the feel because with this box of tricks it only goes into low assist. They are very popular with the rally boys so the steering must still communicate with the driver. If this control box does not work out there is another thats available that works off an adjuster knob on the dash in which you have the control over the amount of assistance.
