I have noticed recently that,at around 40mph,i have been getting a bit of a shudder
through the steering. Took in into a local tyre centre and this was the result.
I really dont understand these results so any help would be great.
They also said that they couldnt get it any better than this and it might still wear the inside of the front tyres still.(there is wear on the inside edge of the tyre}
Tracking solves long term wear, but will not solve immediate shudder.
They should have balanced the wheels and see if they are round and that no pothole bent it slightly oval or curb bent it skew ...
The top picture is the "before" they changed the tracking - your front wheels had toe OUT (positive) 0°01' on left and toe IN (negative) -0°01 on right - that is total toe of zero.
They ONLY changed front toe to -0°05 toe IN - bottom picture. Your rear toe they seemed to have added 1 minute (1/60 °) to 0°10' toe OUT left and 0°14' and toe OUT right. so total toe is 0°24' and the thrust angle is 0°02'
I would recommend a rear toe of zero, thus total toe of zero and thrust angle of zero. At he front -0°05 toe IN is the spec, but combined with the high negative camber, that will wear front tires. I recommend going zero toe front too.
They cannot do much about the high negative camber (-1°18' front and -1°19' / -1°20' rear) that will eat the inside of your wheels. Raising the ride height will make that camber less, but that is generally not cool.
