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
