My 1999 Racetech is the same. 10 years of steering to the right. But goes down the track fine.

I gave it a little more toe on the right wheel, and it is all straight as an arrow, but let go of the wheel in the pits and to the right it goes. Driver isn't having issues with it. Just seemed odd to me.
Thx!

Did you ever try swapping front tires from left to right?

-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

Left rear tire probably has a larger roll out diameter by a small amount than the right rear tire.

Sometimes you can air the smaller one way up and set it out in the sun for a while to stretch it

We haven’t yet but we did measure all four tires for rollout. It was barely anything. I’ve had much much worse

That would be my first suggestion if it was pulling going down track. But I think he said problem was pushing on flat surface. So I would look at the front wheels first, front bearings and then scale and check the weights on both front wheels. Chassis may be tweaked and putting more weight on one wheel. Jack it up and verify that it moves smooth all the way from one side to other.

Did you ever check to see if they welded one of the king pins on with more castor than the other? Not that it really matters because you can't change it now but it's just one other thing to rule out.
