I’m guessing, but a big change for you is the lack of a rear differential. It’s just mere combination of caster, chassis stiffness and axle. :)
You may have not realized how critical seat placement is. Check you chassis manufacture’s web site for recommendations. If it’s near the recommendations, leave it for now, but keep that in mind if you’re struggling with handling issues.
