Why my Durga does not have enough onpower steering?

[edvin]

Well, off road car can't never be good on road car. But still, it seems like my durga does not have on asphalt onpower steering at all. Seems like front tires do not have enough grip. But when moving slowly, with minimum power, it steers enough well. When there is very loos surface, then it has enough onpower steering (sometimes maybe even more than enough).
Has anybody noticed same problem or is my setup absolutely wrong?

I found 2 ways to improve onpower steering on asphalt 1) I glued bowtie tires on front dishes (I mean it seriously!!!) 2) Very stiff rear springs.

But I think both ways are abnormal
