Front suspension changes

Can't find where I first started this thread, so.. At nationals someone suggested my front was too stiff on my 90 Van Diemen if I was not getting some rear wheel spin. I tried disconnecting the front bar at an event 2 wks ago on asphalt and was impressed by the increased turn in and less push, but the rear behaved so badly including bouncing oversteer that I was not thrilled. Today I tried it on concrete and again better turn in and less push, but pretty high on the rear wheel spin and oversteer even after I softened the rear bar. So, it seems I could use a less stiff front bar for a compromise between improved front and messed up rear. Anyone know what is ava for front bars on Van Diemens or know where to look?

I will post link to video soon.
