Appologies if I'm not being very bright but can you explain over the axle camber. Is it that the camber has altered when on the turn so causing weighting problems./

I'd agree. It almost looks as if the coil is wound the wrong way for the spring cup so is being pushed over. Alternatively it's a cheap spring and badly made.

Is wheel refurbing a service WIM offer? Sorry to be asking here, it's just topical to this thread. They look nicely done.

I'm feeling better already, thanks.. I did notice Tony's welcoming commitee. Not sure we rolled the red carpet out properly there. There are loads of Mercedes with pulling, tyre wear and stability problems, well only about 99% of them so you never know we might be able to find you some 'punters' cars to get your hands dirty on... It would be interesting to see what you can do to a problematic car.

Oh, Ok. I said I was prepared to be wrong. So if they will accentuate a negative acherman principle would the opposite create a positive one? You've got me curious now. I read the whole thread regarding drifting the IS. Helpful to have a ready supply of tyres I guess.. I remember a collegue having IS bad inner shoulder wear. Not alone I see. I am indeedy from MBclub, Tony's posts got me interested in popping over here. Nice avatar scorps. Nice technical site.

Hi Chaps Forgive me butting in and without introducing myself but I've just been reading this thread and it made me think about your problem. I'm not sure whether you've reached a successful solution to this yet but it isn't posted here. If I understand correctly you want a greater amount of turn in on the outside wheel relative to the inside one compared to the standard setup. It's a few years (20+) since I read anything to do with Acherman principle so be prepared for me to be wrong here, but iirc the relationship between the steering control arms fixed to the hub and the centre of steering pivot is that the steering control arms follow a line to the centre of the rear wheels with respect to the steering pivot for straight ahead travel, thus are inboard of the steering pivot if the rack is mounted behind the wheel centre. This causes the inner wheel to transcribe a tighter arc when turning. If you want the wheels to transcribe a similar arc to each other the steering arms must follow a line directly back from the steering pivots. Does that make sense so far.? Therefore if you want the outside wheel to transcribe a tighter path than at present than the inside wheel comparatively you need to create a setup of the steering arms being similar to a longer wheelbase vehicle. This could be achieved either with bespoke hub carrier/steering arms or by mounting the track rod joint end outside the steering arms by use of a special coupling to effectively push the angle outward. If you need the outer wheel to transcribe a tighter arc then either be more extreme with the steering control arms or mount the rack in front of the steering pivot and then mount the arms inboard of the pivots again. There may be clearance issues on tight lock but this could be overcome by moving the steering knuckle forwards or by a bespoke steering control rod.
