two newbie questions for a 12l4 outdoor asphalt.

1. What is the rear wheelbase dimension. I'm using a 2nd hand car and noticed that the right side is shorter from the center hole on the bottom pod plate to the outside of the right side rear tire than from that same whole to the outer left side. That seems wrong. So I need to add shimms to the left side. But I need to know what my total rear wheelbase should be.

2. Does thicker dampler lube on the disks add or remove steering. I was told it just "flattens the car out, making more stable" I didn't know it did anything to the steering. I need less steering..and i put some old skool Bolink goo on there that pretty thick.

was that wrong?? I thought it would help for dealing with a transition from a banked oval to the flat infield.
