I got the chance of a freebie Geometry from my OPC and wanted to try going back to a slight toe out on the front for trackday use in my GT3 Mk1.
the datasheet shows 0deg10' per side but I would have expected a neg value if its toe out or am I wrong.
Also the little lines in the picture off a wheel are towards the centre of the car and I thought they would be towards the outside of the wheel pic or at least outside of centre.
The car feels ok but not super twichy like it used to when I had some toe out a couple of years ago.
Does this sound like there has been a misunderstanding and its set to toe in? I don't want to rush back and complain as it was foc but if I'm sure it is set toe in I will have to go back.
Am I right in saying that visualy you wont really see 10' per side ( 1/6th of a degree) so no point in squinting down the side of the car like I was doing last night !!
Interested if anyone has a similar printout for comparison.

Not sure about the actual amounts, but I'm pretty sure it's +ve values for toe out.

No, 10 minutes total, not 10 mins each side. One sixth of one degree at the wheel rim.

Yep, sideways................................

10' total = 5' per side = 1/12 degree at each wheel

But it's still the opposite of what you'd asked for!
