Following the SKOSH chart - your experiences?

No.

But if you use that for manual steering you might want to reduce those caster numbers depending on your front tire width and if the manual steering ratio is 20:1 or 16:1.
I have the flaming river 16:1 215/65-15 cooper cobras up front 275 rear. This was my previous alignment when I had them try to do the best they could from the skosh chart. Street and strip, but not bracket racing.
