So true he said it twice!!! 
One left
One right
He's still trying to centre - but when he does

If you believe you're not crazy, whilst everybody is telling you, you are - then they are definitely wrong!

I have a Viento
Had very little self center and altered the caster fully, set the toe to neutral and it made a big difference.
The car will almost return to centre point on grass from full lock at 20 mph.
No need to over inflate the tyres
so maybe just messs about with the settings if you have somewhere to test it

I would like to know if the ones who have problems with self-centering measured their castor.
Did they really have 5.5 degr castor or more.
Or did the problem occur by the lack of castor?
I def. don't want to drive with springs, hard of soft tires, bad toe-settings or what ever.
So if 5,5 degr isn't enough what would be enough? Productioncars are not higher in castor than the locost.

I think is is mainly sierra hubbed car that have the problem, but stand to be corrected.
I am glad to see the symptom masking is being frowned upon, the SVA testers are fully aware of the bodging and probably investigate further
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Apparently they are aware, as it has been said esewhere that some go so far as to feel/squeeze the gaiters and can fail you for dodgy extra bits. But
technically as they can't see them they can't fail you for it. Part of why I want a complete floor.

MK should have sorted this by now
I can drive the car fast enough no probs without self centering so Im not too bothered.
Ive also passed it at the SVA which is all that matters
Ive done it simply for the test and it works so thats that

I measured the caster at my Indy, and it seems to be something like 7 degrees (not so easy to measure, but can't be too far off). That on its
own should be enough. So as far as I understand, the caster on the Indy isn't the big problem. But what is?
By the way, I asked a friend with a Rush (Sierra uprights) to measure up his caster, and he told me it is about 12 degrees. That seems a bit steep,
doesn't it?
Does anyone have comparable data from similar cars (sierra uprights) which do self-center? I know that the Striker does (but don't have the
data). What about Tigers, Westfield SDV, GTS, Luego, MNR?!?!?
I definately agree that it requires a good solution. I hope to pass SVA with the tricks described here, but be honest; you want a good driving car in
the end, and to 99% that means decent self-centering (amongst other things). So after SVA I want it sorted out, no compromises.
Maybe someone with the right capabilities should jump in and fabricate a correct working front suspension system which fits the Indy. I'd be
interested...

The amount of self-centering you get is a result of the amount of weight on the front of the car and the amount of castor. A heavy car needs little
castor; a light car like the Locost needs quite a lot.

mmmmmmmmmmm.........my car is lighter than a 7 as it is rear engined.
At 3 degrees castor it attempts to center. At 7 degrees it centers easily. So a 7 should center between 5-6 degrees.
