Wheelies - Hypothetical Combo

Long, low, ladder bars. Geometry matters. You want the leverage pushing to the front and below the front tires, not lifting the rear like ss springs. See traction tutorials on you tube that explain cg, and lift/squat line, instant center.
Got my first wheelies in an aluminum head small block car with ladders, ENTIRELY different chassis reaction from my iron head big block ss spring car.

One of the best answers ever on a forum. EVER.

Geometry matters and IF you want the chassis to pitch rotate (wheelie) you want a fairly long, fairly low Instant Center.

On my 4 link with a 4 speed I needed my IC (going from my memory because once I learned how stupid the starting point for IC that was used in 1989 was dead wrong and that was half the wheel base out and cam high up…which is great for tire limited, low HP, foot brake stuff as a starting point…maybe…so I had my IC all over the place getting it right) was 107 inches out and 4-5 inches up.

Most cars run the IC way too high and way too high IMO. Then they end up using up the shock adjustment trying to control the axle.
