K1 rear end stepping out

[paulainscow]

Hi all

Im running a K1 Aero, on gym hall surface, and struggling to keep back end under control

Are there any basic steps to follow to keep back end of the car more stable going in and out of corners?

Ive tried varying ride heights last night and found 21/22 ml helped, but going above or below that increased the problem

Running blue and red springs, varying oils between 25 and 35 throughout trying to get this under control. Find that 32.5 & 35 wt gives me best grip

Any advice would be great, thanks

What's your cambers, toe-ins and anti-squat all round as well as tyre choice?

Hi Dan

Camber is -1 all round, toe-in I need to check, thats something Im yet to try (only back racing for two year) and anti-squat about 3mm

what tires are you running? i run mini pin 1 all round but if you need more rear grip then mini pin 2 would help. or if there is some carpet then darts would be good.

ball diffs or gear diffs?

That's quite a lot of anti-squat, and anti-squat tends to make the car rotate more in a corner. Perhaps try less of this to this to keep the rear more planted :)

Thank you Dan, I will try reducing this to one mil and work from there

Really appreciate your advice :)

This will help as well. Less Moments. Longer lever, more swing.

Sorry to sound dumb, but whats that mean?
