Electric power steering

[Stradale493]

Following this thread with interest. I've picked up a Corsa B EPS column "just in case" I decide to go down that route at some point in the future - certainly prices were steadily rising and reasonably priced items seem to get snapped up pretty quick. No hurry for my though as I don't currently mind the weight of the "shoulder powered" steering

Hi Dave,
I'm very interested in your EPAS thread as it clearly opens up suspension and steering geometry options to improve stability. My concern/question however is how does this affect the steering feed back as my only long term experience of EPAS is several years ago with a Honda S2000 which was incredibly vague and had little to no feel of the limit, especially in the wet. I did a lot of research last night and this is a common criticism unless you go to the very latest generation of technology (apparently a Porsche system is one of the leaders) which is clearly not an option for the majority of us. Most engineering solutions have some inbuilt compromise, which I'd be prepared to accept as long as it doesn't replace one issue with another. I have a long wait for my chassis so want to use the time to review and plan the various build options and collect and prepare all the parts. I know steering 'feel' will be subjective but am interested to understand your experience/thoughts.

regards
Steve

I think it depends on what you're doing with the car. I have no PAS and a quick rack - 2.5 turns lock to lock - on a Hawk with usually 205 front tyres on 6" rims. Really not great for parking/3-point turns etc., but once off and moving no problem at all; great feel at speed. If I lived in town and used it around town a lot I would be thinking of it. Castor/camber settings have an effect too.

Plus one Chris! And I run 8 inch on the front with 225*50*15's! You soon learn not to attempt to turn the steering wheel until the wheels are rotating! And yes, it improves with speed and has great feedback.

For those interested in the install and electronics required, found this site with loads of great info................

http://www.super7thheaven.co.uk/blog...steering-epas/

You can navigate around the various pages, well worth a read. It warns of the dangers of using some of the cheap units that are available to give false speed signals into the Corsa Control unit and some have drifted badly with temperature.

Interesting site - he sounds knowledgeable.

Corsa C EPAS - Modified a lot to fit MK1 Rally Escort..............all the original collapsible shaft to the steering wheel has been removed and escort steering column grafted on.
