Those values are toe open for track and zero toe for street. Problem solved: none is toe in so tramline is still present.First of all change tyres to Michelin Pilot Super sports. You’re running the18/19” wheel stagger so no problem there. The Pirellis seem to exacerbate the tramlining effect. I’ve used Rudi Gales’ Street Specs. No idea of the castor specs but have added a bit more negative camber (now -1.7 deg each side) at the front to counter understeer while going to zero toe instead of toe-out. Less tramlining but not eliminated. I’m currently on Hankook R-S4 rubber 215/45x17 front, 235/40x18 rear. My front tyres seem to be wearing more evenly now too.
It’s very important that specs both sides are exactly the same. Some here seem to have accepted alignment specs that differ slightly left and right. Not good. Our cars are very sensitive to spec changes. I’ve also got uniball bushes that tighten up the rear so standard rear toe-in (40’ each side) might be better for stability without these.
