Setting to close toe to about zero did not have much effect. I'll try playing with camber next. Also, I'll try changing the wheels to the stock 14" pressed steel ones.

alga, one thought. Maybe it's something with your steering column, maybe some awkward angle causing the steering to stuck?

I must admit from reading this thread it does point to perhaps a more simple issue, you should always try the easy and obvious first.
I've been to 5 SVA's and IVA's we had a self centering problem on 3 this was always sorted with an adjustment of the toe on the day, none had been set up in advance just somewhere close with string and laser levels. On the road the lack of perceived self centering has not become a problem. We have a broad variety of cars most are 7's, Robin Hood, MK, several Locost/Haynes, only one has Cortina hubs and is still in build so can't comment on that however the Sierra hub cars are realy not a problem on the road and on some we have just shimmed the top and or bottom wishbones with washers. |

If somebody could come up with a new design wishbone, I for one would definately be investing in them. I cant understand why this wasnt designed in the first place. Apparently Mk Indys suffer the same. Dan |

Caster angle
Hi ime a little confused on this one too. The offset of the upper wishbone is 23mm giving a positive caster angle of approx 7 degrees which is all you really need. So why do we need offset mushrooms. Am I missing something?

spud69, could you chime in on the topic? You mentioned several times that you recommend the caster angle set so the car just starts to self-centre. How do you adjust the angle? What's the downside of having more caster on the Roadster?

The mushroom is not meant to be used to overcome the lack of caster. The mushroom takes into account the upright doesn't pivot about its centre line in the donor vehicle. Martin Keenan devised the mushroom to overcome this problem. The lack of caster is a design flaw in my view and the design should have been corrected years ago or at least a sticky put in place so new builders would know to build in extra caster as they built their chassis. Rotating the mushroom and adding undersirable toe out to get it to self centre is just bodging round the issue. 5 degrees should be considered a minimum but some people arn't getting anywhere near as much.
