Wheels-in-motion. I guess this is your "thing". What do you make of the kit they use and the deal I got?

The machine gathers sufficient information so no problems there. The problem you can get is with the operator, why didn't they adjust or mention the castor and did they investigate why the rear cambers are to far toward positive?

What did it cost you for front/rear toe adjustment?
 
i know what you mean guys but everything was out before now it's better setup than before and honestly it feels better, it was start to whip back a bit when turning left but it doesnt anymore.

£57 all in. Nitrogen free:)
 
Another vote here for Wheels-in-motion - the alignment you get done is only as good as the guy doing the alignment. A nice fancy machine helps (WIM have one too), but the guy doing the alignment really needs to understand the effect of the minute changes he's making on the way your car drives.

Not saying STS aren't good - but being a chain, I wonder if they're as committed to getting it right as WIM are. Most alignment places just 'get it in the green zone'. The problem with that approach is that the green zone itself is actually quite big, and the C class in particular is very particular about its alignment settings.
 
Castor WILL effect tyre wear. Any incorrect geometry will. More importantly it will effect the "pull" to the left and right.

Im not saying the car will not "feel" good. Maybe a placebo effect? lol

Castor will NOT affect tyre wear.

Think of it like those motorebikes which have steeply sloping forks and the front wheel is way out in front. That is an extreme castor angle.

Whether those forks are steeply angled or less steeply angled makes no difference to the wear on that front tyre. ( except if he/she was perhaps using a roundabout constantly).

Yes and no...... Longitudinal the castor cannot make the tyre wear but as the steering is turned the castor position aids the camber migration (inner wheel toward positive, outer toward negative) if the castor is wrong then the migration will allow the cars weight to become outside of the steer axis and wear the tyre.
 
Only in the sense of it was OK. He said when you are talking tolerances of a third of a mm it would be OK. Have I got it wrong:confused:

They are wrong..... From the static target you have 50' +- tolerance, you currently have 77' or 3/4 of a degree depending on your language.

Castor cannot be expressed in mm because it's position is gained from the camber change taken at 10 or 20 degrees of lock and measured in degrees or decimal degrees. The castor "error" can be triangulated by setback which can be measured in mm.
 
LOL. They way I think about it is my suspension leans.7 of a degree more than it should but it feels really good so I'm happy:)

It's 77' or 3/4 of a degree less but at the end of the day it's how she drives that really matters.

If the castor were to be an issue the car would pull left and be slow to return the steering on a left turn, if this is not the case then happy days.
 
I,ll pay great attention tomorrow! What's the keenness for nitrogen all about. I just said yes!

Argumentative topic in many forums..... Basically dry Nitrogen is an inert gas not influenced by heat or cold like compressed air. The molecule is larger than air so less likely to seep through the tyre membrane thus maintaining better pressure.

In addition since the gas is inert (+- one atmosphere) the handling will be more predictable as will the tyre wear.... The argumentative part in my opinion is belayed if the inflation is free... In this case even if the benefit is 1% it's a free 1%.
 
Am I alone in wanting 'wheels-inmotion' to check over my car ?

I sense rather useful experience being passed on .......
 
There was quite a hot thread on the subject a while ago but I cant seem to find it.

From recollection, the general consensus was that it was a bit of a gimmick and offered very very little benefit if at all - but as said above... if it is free then who cares.

No you're not alone... I'm just a litle wary of turning up with my old W124 with the wrong size wheels and offsets and the wrong spring heights on the rear only to be told the geometry is all screwed and it cant be sorted. :D

I'm pretty local too.
 
Careful, you'll get me thrown out of here :doh: Obviously my intentions are only to help and educate as best i can.
