Adding grip to the kart while keeping it rigid

We are struggling with the kart coming in to late. we have tried going softer on the axle and the cart wont come of the corner That’s why we want to try to keep it rigid.
we have also tried the following:
tyre pressure
long hubs
decrease caster

any suggestions?

What kart, what tire, what engine, what track conditions, what tire pressure?

OTK, vega blues, briggs, 18 degrees Celsius with winds, and 15.5 tyre preasure

vega blues are softer then vega reds and harder then vega yellows

Have you tried raising the rear CoG?

We’ve tried it, I just don’t like the feeling of it, it feels to sensitive. think it’s the only option.

Sound like you need more Ackermann or caster. Might work the kart and tires more. Go harder on the axle try the A or H.

If going softer didn’t help go the other way

Running MXC wheels?

Thanks I’ll try adding Ackerman I’ll let you know

Standard OTK or 4-cycle OTK? Is that conventional rear width rules or the narrow Canadian rear width? 50”??

4 cycle otk with the Canadian 50 rule
