REAR GRIP

[Alex]

By moving the axle up you increase grip or you loose grip?With my CR31ST I am having too much rear grip with the axle up, axle B, birel seating measurements, Tyres MG yellow, 0.55bar pressure and short freeline hubs. Somebody told me to move the axle down to reduce rear grip. is this true. What can i do avoid too much rear end grip.

Alex,

When you move the axle up and lower the chassis, that will give you less side bit, but will give you more traction in a straight line. When you move the axle down and the chassis up that will give you more side bit, but less traction in a straight line. The person you were talking to might of mistaken the axle for the chassis when he was talking ride height.
To reduce rear grip, if you already have the axle up (chassis down), with a B axle with short hubs. You could Try giving the front of the kart more grip.
-Open the front track with (We usually run it as 5 lines wide to start with, but have gone to 7 lines in some cases)
-More caster
-Raise front ride height
-If non of these work, then you need to move the seat forward, and tilt it back.

On a side note, if the track you are racing on has no rubber and is a very green track, Sometimes going softer will give you the grip cause the track doesn't have the rubber that the kart needs to work the way it should, so the way you get the kart to work is to make the chassis softer.
Hope this helps
