something that adds significantly in karting, is weight distrubution. Many, and really, many people who go out karting
do not position themselves correctly while cornering. They tend to position themselves in a 'motorcycle' pose;
corner to the righ; lean to the right. corner to the left, lean to the left. this is correct for motorcyclists, not for karting.
The goal is to have the most grip in the outer wheels - if you lean to the inside wheels, you tend to bring the balance
to the left, thus the weight pressure to the inner wheels; causing these to get the most grip, but this has the result that
the inner wheels have the tendency to 'press' or 'steer' the kart into understeering.
When you instead shift your weight to the outer wheels of the corner;
thus; corner to the right, lean to the left, corner to the left, lean to the right, then you shift the weight balance to
the outer wheels causing them to get the most grip and steering the car 'inwards'.
BTW, allthough the experience is fun and good, tire screeching is a killer for laptimes. You'd want to minimize tire
screeching, and minimize track distance. Taking the corners as tight as possible with the most speed possible.
Obviously material depends significantly. I've had blazingly good laptimes at a indoor kart centre here, then took another heat in another kart [despite it being the same model] and i could not come close to my previous laptimes, despite having clear runs.
And btw holy topic-revival batman!
good to see the search function is used though
