    Question HELP please ....... Steering Question

    I know it`s technical, but not run of the mill astra

    On a steering rack, can you run different length trackrod ends, i.e. one 20mm longer that the other, or will it effect the steering ?

    Is the rack gonna be central to the car, or offset (to make it fit )?

    if its offset then i would imagine that running different lenght track rod ends will just compensate for the offset position

    It shouldn't make that much difference as the track rod ends will screw in/out to adjust the toe. All you might get is a difference in full lock from one side to the other, but it's hardly gonna be noticable.

    So get to it

    That`s what I thought, but a guy at work reckons it`ll effect the handling under cornering conditions, where the trackrods pivot in the knuckle on the rack, because of their different lengths.

    I can't see that happening TBH as hopefully you'll have the suspension all firmly fixed, so it can only pivot about the axis it's meant to, so all the steering rack will be doing is causing it to rotate about that fixed centre.

    And it's the geometry (camber, castor and toe) that affect the handling, not the push/pull of the rack

    if the steering rack is offset tho, in theory all your doing is compensating the difference in length to the knuckle, would not imagine that it'll even make a difference to the handling in the corners, suppose its only like a kit car.

    That's a geometry thing too, and more to do with the set up of the front end as a whole, rather than the steering rack per se
