Disco1 softer front anti-roll bar?

[KhunMoo]

Ny of you guys know if there is a softer anti-roll bar in the L-R models than the OE bar in the D1? I have slightly firmer king springs fitted which tend to lessen body roll anyway, so I'm looking for a softer bar to impove articulation without losing too much on-road handling.

I do not wish to go to disconnects, just a less stiff bar.

Any ideas?
